If the threshold energy of the reaction 2016O(n, γ) 170 is 15.6 MeV, then the atomic mass of 170Ol can be calculated.

Given:Atomic mass of Ol (15.996415 amu)Atomic mass of neutron (1.008665 amu)M (Ol) = 15.996415 amuM (neutron) = 1.008665 amu Threshold energy of the reaction, E = 15.6 MeV The threshold energy (E) is the minimum amount of energy that an incoming neutron must have to trigger the nuclear reaction or the amount of energy that is needed to supply for the reaction to proceed.

The atomic mass of 170Ol can be calculated as follows:E = [M (n) + M (2016O) - M (170O)] x c²Where c = speed of light, M (n) = mass of neutron, M (2016O) = mass of oxygen-16M (170O) = mass of the oxygen-17, the product of the reaction.Rearranging the above equation:  M (170O) = [M (n) + M (2016O) - E/c²]Thus, M (170O) = [1.008665 + 15.994915 - (15.6 x 10⁶ eV/ (3.0 x 10⁸ m/s)²)] amuM (170O) = 16.98803 amuTherefore, the atomic mass of 170Ol is 16.98803 amu.

The ionic bond between Na and P has formula unit Na3P.

What is the formula unit?

Formula units is the chemical formula which gives all the ions present in the lowest ratio possible to make it neutral charge of an ionic compound. For example, the formula unit for sodium chloride can be written as NaCl where charge on Na is +1 and charge on Cl is -1. So to make it neutral they can be cancelled and written as NaCl.

In sodium phosphide, the charge on Na (sodium) ion is +1 and the charge on the P (phosphorous) ion is -3. Therefore, make the charges neutral, 3 Na ions need to be added to 1 P ion. Formula units can be used to describe or represent the molecules or the elements which make up a substance.

Claim: The jump in ionization energy from I2 to I3 is the largest.

Evidence: You would have to search some up but the jump is from 1450.7 kj/mole to 7732.7 kj/mole. You could also say that magnesium has an electron configuration of [Ne] 3s2 and after removing the two outer valance electrons the next electrons being removed would be core electrons.

Reasoning: Core electrons need lots of energy to remove from the atom, while valance electrons are easy to remove. The 2nd electron removed is a valance electron, while the 3rd electron removed is a core electron. Thus, we should expect that the energy needed to remove a hard to remove electron (the 3rd electron) would be much more than the energy needed to remove the easy to remove electron (2nd) and we should expect a large jump of ionization energy from I2 to I3.

The value of for a mixture of polymer is 0.715 if the and the solvent b assume vs/rt = 1/6 and a fudge factor of 0.34 .

Option C is correct.

A polymer is any of a class of normal or engineered substances made out of exceptionally huge particles, called macromolecules, which are products of more straightforward compound units called monomers. Numerous minerals and man-made materials are based on polymers, which are the basis of many living materials.

The following formula can be used to determine the value for a mixture of solvent b and polymer a:

                          = [(1-)/(1-)](1/2)

where p and s are the particular volumes of the polymer and dissolvable, individually, and vs/rt is the volume part of the dissolvable.

             p = 9.0 (cal/cm³)0.5 s

              = 7.5 (cal/cm³)0.5 vs/rt

                           = 1/6

fudge factor = 0.34

Substituting these values , we get:

             = [(1-0.375)/(1-0.375+0.34x0.375)](1/2)

                 = [(0.625)/(0.8745)](1/2)

Answer:

A 1.732 g sample of iron is heated in air. It oxidizes to form a product with a mass of 2.205 g. What is the empirical formula of the product? FeO 4. Caffeine is made of 49.48% carbon, 5.19% hydrogen, 28.85% nitrogen, and 16.48% oxygen by mass.

Explanation:

The empirical formula of the product formed by the reaction of iron and oxygen is FeO.

Let's consider the following generic chemical equation:

Fe + O₂ ⇄ FexOy

According to the law of conservation of mass, the sum of the masses of the reactants is equal to the sum of the masses of the products. The mass of O₂ that reacted, and remains in the oxide is:

\(mFe + mO_2 = mFexOy\\mO_2 = mFexOy - mFe = 2.205 g - 1.732 g = 0.473 g\)

The oxide has 1.732 g of Fe and 0.473 g of oxygen and a total mass of 2.205 g. To determine the empirical formula, we need to calculate the percent composition.

\(\%Fe = \frac{mFe}{mFexOy} \times 100 \% = \frac{1.732 g}{2.205 g} \times 100 \% = 78.55\%\)

\(\%O = \frac{mO}{mFexOy} \times 100 \% = \frac{0.473 g}{2.205 g} \times 100 \% = 21.45\%\)

Now, we will divide each percentage by the atomic mass of the element.

\(Fe: 78.55/55.85 = 1.406\\O: 21.45/16.00 = 1.340\)

Finally, we divide both numbers by the smallest one.

\(Fe: 1.406/1.340 \approx 1 \\O: 1.340/1.340 = 1\)

The empirical formula of the product is FeO.

Two approaches to calculate the number of carbon monoxide molecules in 45 pg are using Avogadro's number or molar mass.

1) Approach using Avogadro's number:

Determine the molar mass of carbon monoxide (CO). The molar mass of carbon is approximately 12.01 g/mol, and the molar mass of oxygen is approximately 16.00 g/mol. Therefore, the molar mass of carbon monoxide (CO) is: 12.01 g/mol (carbon) + 16.00 g/mol (oxygen) = 28.01 g/mol

Convert the given mass of carbon monoxide to moles. 45 pg = 45 x 10⁻¹² g (since 1 pg = 10⁻¹²  g) moles = mass / molar mass moles = 45 x 10⁻¹²  g / 28.01 g/mol

Calculate the number of molecules using Avogadro's number. Avogadro's number states that there are 6.022 x 10²³ molecules in one mole of a substance. Number of molecules = moles x Avogadro's number of molecules = (45 x 10⁻¹²  g / 28.01 g/mol) x (6.022 x 10²³ molecules/mol)

Approach using molar mass

Determine the molar mass of carbon monoxide (CO). The molar mass of carbon monoxide (CO) is calculated as 28.01 g/mol (as explained in Approach 1).

Convert the given mass of carbon monoxide to moles. 45 pg = 45 x 10⁻¹² g (since 1 pg = 10⁻¹²  g) moles = mass / molar mass moles = 45 x 10⁻¹²  g / 28.01 g/mol

Use stoichiometry to calculate the number of molecules. The balanced chemical equation for carbon monoxide (CO) is: 1 mole of CO = 6.022 x 10²³molecules of CO

Since the stoichiometry is 1:1, the number of molecules is equal to the number of moles. Number of molecules = 45 x 10⁻¹²  g / 28.01 g/mol

Both approaches involve using the molar mass of carbon monoxide and Avogadro's number to convert mass to moles and then to molecules.
