Explanation:

Biomass combustion is referred to as a process in which organic materials are burnt and their remains are used to produce energy.

The process of combustion is very simple it refers to the burning of biomass which include wood, farm waste, and crops which are further used to produce or generate energy in the form of electricity and also heat, it can be termed as renewable energy that utilized the energy of biomass to produce another form of energy.

The Grate furnace method is one of the common methods used for biomass combustion and comprises several steps for the recovery of energy.    

The first step consists of drying up the biomass by removing all the moisture using heat. The next step includes the production of flames and heat by combusting hydrogen present in it. After that, the remaining solid waste will undergo combustion in the presence of oxygen.

The last step includes the disposal of ash which gets accumulated due to incombustible materials like sand.

Answer:

An intermolecular force is the force of attraction or repulsion which act between neighboring particles (atoms, molecules, or ions). Whereas the covalent bonds are the interatomic linkage that results from the sharing of an electron pair between two atoms.

Intermolecular forces hold molecules together in a liquid or solid. Intermolecular forces are generally much weaker than covalent bonds.

the molar concentration of \(AsF_5\) (g) at equilibrium is 0.0226.

We  consider the percent decomposition and the initial molar concentration of  \(ASF_5\)(g).

The percent decomposition of 27.7% means that 27.7% of the original moles of \(ASF_5\)(g) have decomposed. Therefore, the remaining moles of \(ASF_5\)(g) at equilibrium would be 100% - 27.7% = 72.3% of the original moles.

[ASF5] equilibrium = (72.3/100) * [ASF5]₀

= 0.723 × 0.0313 M = 0.0226 M

This equation gives us the molar concentration of \(ASF_5\)(g) at equilibrium.

The theoretical yield of MgO is 0.84 g. The limiting reactant or limiting reagent is a reactant in a chemical reaction.

The limiting reactant or limiting reagent is a reactant in a chemical reaction that determines the amount of product that is formed. Identification of the limiting reactant makes it possible to calculate the theoretical yield of a reaction.

The reason there is a limiting reactant is that elements and compounds react according to the mole ratio between them in a balanced chemical equation.

Mg is limiting reagent so amount of MgO depends on the amount of Mg.

Mg  +  O₂ \(\rightarrow\) 2 MgO

1 mol                        2 mol

Molar mass of Mg = 24 g/mol

Molar mass of MgO = 24 + 16 = 40 g/mol

24 g of Mg gives 80 g of MgO

mass of Mg for trial 1

Mass of Mg = mass of Mg metal, crucible and lid - mass of empty crucible and lid

Mass of Mg = 26.931 g - 26.679 g

Mass of Mg = 0.252 g

24 g of Mg ≅ 80 g of MgO

0.252 g of Mg ≅ X g of MgO

X g of MgO = 0.84 g

theoretical yield of MgO=0.84 g

The answer is C.

The reactants are charcoal that is unlit + oxygen and the products are the burnt charcoal + energy.

So for every combustion reaction like this one, CxHy is the wood. So before you light the wood, it is actally a reactant together with oxygen, because without oxygen the wood will not burn. So under the influence of heat, wood produces substances like carbon dioxide and heat, the moment you see wood burning it it already producing products, CO2 and heat (which is the fire). This is a combustion reaction.

Answer:

Though the word atom originally denoted a particle that cannot be cut into smaller particles, in modern scientific usage the atom is composed of various subatomic particles. The constituent particles of an atom are the electron, the proton and the neutron.

The electron is by far the least massive of these particles at 9.11×10−31 kg, with a negative electrical charge and a size that is too small to be measured using available techniques.[39] It was the lightest particle with a positive rest mass measured, until the discovery of neutrino mass. Under ordinary conditions, electrons are bound to the positively charged nucleus by the attraction created from opposite electric charges. If an atom has more or fewer electrons than its atomic number, then it becomes respectively negatively or positively charged as a whole; a charged atom is called an ion. Electrons have been known since the late 19th century, mostly thanks to J.J. Thomson; see history of subatomic physics for details.

Protons have a positive charge and a mass 1,836 times that of the electron, at 1.6726×10−27 kg. The number of protons in an atom is called its atomic number. Ernest Rutherford (1919) observed that nitrogen under alpha-particle bombardment ejects what appeared to be hydrogen nuclei. By 1920 he had accepted that the hydrogen nucleus is a distinct particle within the atom and named it proton.

Neutrons have no electrical charge and have a free mass of 1,839 times the mass of the electron, or 1.6749×10−27 kg.[40][41] Neutrons are the heaviest of the three constituent particles, but their mass can be reduced by the nuclear binding energy. Neutrons and protons (collectively known as nucleons) have comparable dimensions—on the order of 2.5×10−15 m—although the 'surface' of these particles is not sharply defined.[42] The neutron was discovered in 1932 by the English physicist James Chadwick.

In the Standard Model of physics, electrons are truly elementary particles with no internal structure, whereas protons and neutrons are composite particles composed of elementary particles called quarks. There are two types of quarks in atoms, each having a fractional electric charge. Protons are composed of two up quarks (each with charge + ) and one down quark (with a charge of −  ). Neutrons consist of one up quark and two down quarks. This distinction accounts for the difference in mass and charge between the two particles.

The quarks are held together by the strong interaction (or strong force), which is mediated by gluons. The protons and neutrons, in turn, are held to each other in the nucleus by the nuclear force, which is a residuum of the strong force that has somewhat different range-properties (see the article on the nuclear force for more). The gluon is a member of the family of gauge bosons, which are elementary particles that mediate physical forces.

All the bound protons and neutrons in an atom make up a tiny atomic nucleus, and are collectively called nucleons. The radius of a nucleus is approximately equal to {\displaystyle 1.07{\sqrt[{3}]{A}}}{\displaystyle 1.07{\sqrt[{3}]{A}}} femtometres, where {\displaystyle A}A is the total number of nucleons.[45] This is much smaller than the radius of the atom, which is on the order of 105 fm. The nucleons are bound together by a short-ranged attractive potential called the residual strong force. At distances smaller than 2.5 fm this force is much more powerful than the electrostatic force that causes positively charged protons to repel each other.

Atoms of the same element have the same number of protons, called the atomic number. Within a single element, the number of neutrons may vary, determining the isotope of that element. The total number of protons and neutrons determine the nuclide. The number of neutrons relative to the protons determines the stability of the nucleus, with certain isotopes undergoing radioactive decay.

The proton, the electron, and the neutron are classified as fermions. Fermions obey the Pauli exclusion principle which prohibits identical fermions, such as multiple protons, from occupying the same quantum state at the same time. Thus, every proton in the nucleus must occupy a quantum state different from all other protons, and the same applies to all neutrons of the nucleus and to all electrons of the electron cloud.

A nucleus that has a different number of protons than neutrons can potentially drop to a lower energy state through a radioactive decay that causes the number of protons and neutrons to more closely match. As a result, atoms with matching numbers of protons and neutrons are more stable against decay, but with increasing atomic number, the mutual repulsion of the protons requires an increasing proportion of neutrons to maintain the stability of the nucleus

The separation of the components of a mixture is based upon the fact that each component has different physical properties. The components of a mixture are separated based on their physical properties.

Most of the things we see around us are mixtures, but what is a mixture? A mixture is the physical combination of two or more pure substances that can be separated using physical means. Air, milk, soil, ocean, juice, blood are all mixtures.

Mixtures are not chemically bound together, unlike compounds, that is why they can easily be separated using physical means. For example, if we pour salt into a glass of water and dissolve it, the ions in the salt do not chemically bind to the water molecules, hence, do not need to be separated chemically. The salt crystals can be gotten back by evaporation or crystallization.

Nuclear fusion is the process which forms all elements up to and including iron, except light elements such as hydrogen and helium.

Nuclear Fusion reactions power the solar and different stars. In a fusion response, two mild nuclei merge to shape a single heavier nucleus.

The method releases power due to the fact the total mass of the ensuing single nucleus is less than the mass of the 2 unique nuclei. The leftover mass turns into electricity.

If ATP is hydrolyzed under standard conditions except that pH is less than the standard pH, the free energy released will be less than -30.5 kJ/mol. This is because the concentration of H+ ions is greater than the standard pH, and this can affect the ionization of the phosphate groups in ATP.

ATP is hydrolyzed under standard conditions except that pH is less than the standard pH:If ATP is hydrolyzed under standard conditions except at pH less than the standard pH, it means the pH of the solution is more acidic than the standard pH. In this case, the concentration of H+ is greater than the standard pH, and this can affect the ionization of the phosphate groups in ATP. Because the phosphate groups have pKa values of around 6 and 7, the concentration of H+ ions can affect the protonation of the phosphate groups in ATP.

In this scenario, the free energy released by the hydrolysis of ATP will be less than -30.5 kJ/mol because the reaction is not taking place under standard conditions. Therefore, if ATP is hydrolyzed under standard conditions except that pH is less than the standard pH, less free energy will be released. This is because the reaction is not occurring under standard conditions and therefore the standard free energy change does not apply.

Explanation:

the rate of appearance of O2 at that particular moment would be 0.280 mol/min for  no2 is equal to 0.560 mol/min at a particular moment.

The balanced chemical equation for the reaction that produces NO2 and O2 would be helpful to answer this question. Assuming the reaction is:

2 NO → 2 NO2 + O2

The stoichiometry of the reaction tells us that for every 2 moles of NO that disappear, 2 moles of NO2 and 1 mole of O2 are produced. Therefore, the rate of appearance of O2 would be half the rate of appearance of NO2, or:

Rate of appearance of O2 = (0.560 mol/min) / 2 = 0.280 mol/min

So the rate of appearance of O2 at that particular moment would be 0.280 mol/min.

The molarity of the KOH solution is 0.0707 M.

In a neutralization reaction between H2SO4 and KOH, the number of moles of H2SO4 equals the number of moles of KOH.

First, let's calculate the number of moles of H2SO4:

moles of H2SO4 = volume of H2SO4 (in L) x molarity of H2SO4

moles of H2SO4 = 10.0 mL x (1 L/1000 mL) x 0.121 mol/L

moles of H2SO4 = 0.00121 mol

Since KOH and H2SO4 react in a 1:1 molar ratio, the number of moles of KOH is also 0.00121 mol.

Next, let's calculate the molarity of the KOH solution:

molarity of KOH = moles of KOH / volume of KOH (in L)

molarity of KOH = 0.00121 mol / (17.1 mL x 1 L/1000 mL)

molarity of KOH = 0.0707 mol/L or 0.0707 M

Therefore, the molarity of the KOH solution is 0.0707 M.

The information that this particular element has seven electrons in its outer energy level tells you that this element is highly reactive and is likely to form compounds with other elements. This is because the outermost energy level of an atom is called the valence shell, and it is the most important factor in determining an element's chemical reactivity.

The electrons in the valence shell are involved in chemical bonding, and elements tend to react in ways that fill or empty their valence shells.An element with seven electrons in its outer energy level will be in Group 17, also known as the halogens. Halogens are highly reactive nonmetals that are able to form compounds with many other elements. This is because they only need to gain one electron to fill their valence shell, making them very reactive.

Chlorine, for example, is a halogen with seven electrons in its outer energy level, and it readily reacts with other elements such as sodium to form compounds like sodium chloride (table salt).In contrast, elements with full valence shells (like the noble gases) are much less reactive because they do not need to gain or lose any electrons to fill their outermost energy level. Therefore, the information that this particular element has seven electrons in its outer energy level tells you that it is highly reactive and is likely to form compounds with other elements.

For the reason stated above, NO2 deviates more from ideal gas behaviour compared to CO2.

CO2 has dipoles that cancel out so the molecule is not really polar because it has no dipole moment. NO2 has a dipole moment and greater intermolecular interaction. NO2 deviates more from ideal gas behavior compared to CO2.
