When an electrical utility charges higher prices during the day than at night, it is practicing:______.
Answers
When an electrical utility charges higher prices during the day than at night, it is practicing is peak load pricing.
What is peak load pricing?The demand for the many goods is larger during certain times of the day or week. For example, the roads are congested during rush hours during the morning and evening commutes. Electricity has larger demand during day than at night. Ski resorts have large (peak) demands during weekends, and smaller demand during the week.
Economic efficiency is greatly improved by charging the higher prices during peak times. If utility were required to charge a single price at all times, it would lose ability to charge consumers an appropriate price during peak demand periods. Charging higher price during peak hours provides an incentive for consumers to switch consumption to off-peak hours. This saves the society resources, since costs are lower during those times.
An example is an electricity consumption. If consumers are charged higher prices during the peak hours, they are able to shift some electricity demand to night, the off-peak hours. Dishwashers, laundry, and the bathing can be shifted to off-peak hours, saving the consumer money and saving society resources. Electricity companies also promote the “smart grid” technology that automatically turns thermostats down when individuals and families are not at home… saving the consumer and society money.

PLEASEEEE HELP DUE IN 2 HOURSS PLEASE!! 15 POINTS!!!!Someone decides to swap out nitric acid (HNO3) for hydrogen
chloride (HCI), given that it will be much stronger due to opposing dipole
forces. Explain if they are correct or incorrect and why.
*
Answers
Explanation:
The claim that hydrogen chloride (HCl) would be much stronger than nitric acid (HNO3) due to opposing dipole forces is incorrect.
Both HCl and HNO3 are strong acids, meaning that they dissociate completely in water to produce H+ ions. The strength of an acid is determined by the degree to which it dissociates in water. In other words, the stronger the acid, the more H+ ions it produces in water.
The dissociation of HCl and HNO3 in water can be represented as follows:
HCl + H2O → H+ + Cl-
HNO3 + H2O → H+ + NO3-
As we can see, both HCl and HNO3 produce H+ ions in water. Therefore, the strength of an acid cannot be solely determined by its dipole forces.
In addition, it's important to note that HCl is a much more volatile and corrosive acid than HNO3. It can cause severe respiratory and skin irritation when it is inhaled or comes into contact with skin. Therefore, switching HNO3 for HCl could be dangerous and should not be done without proper precautions and expert knowledge

Answers
The correct sequence of events in cholesterol synthesis is HMG –CoA > phosphomevalonate > isopentenyl pyrophosphate > dimethylallyl pyrophosphate > geranyl pyrophosphate > farnesyl pyrophosphate > squalene > lanosterol > cholesterol.
HMG-CoA: The precursor of cholesterol is HMG-CoA (3-hydroxy-3-methylglutaryl-coenzyme A). The synthesis of HMG-CoA occurs in the cytoplasm of cells.
Isopentenyl pyrophosphate: HMG-CoA undergoes a series of reactions to form mevalonate. Isopentenyl pyrophosphate is formed from mevalonate by the conversion of mevalonate to mevalonate-5-phosphate.
Dimethylallyl pyrophosphate: Isopentenyl pyrophosphate condenses with dimethylallyl pyrophosphate to produce geranyl pyrophosphate.
Geranyl pyrophosphate: Geranyl pyrophosphate is transformed into farnesyl pyrophosphate by the addition of another molecule of isopentenyl pyrophosphate.
Farnesyl pyrophosphate: Farnesyl pyrophosphate is transformed into squalene by the removal of two phosphate groups.
Squalene: Two squalene molecules join together to form the first cyclic intermediate, lanosterol.
Lanosterol: Lanosterol is then transformed into cholesterol through a series of reactions.

Calculate the amount of pure CaCO3 that could theoretically neutralize the H+ in one-year acid rain if a 1-hectare site received 1400 mm of rain per year and the average pH of the rain was 5.5
Answers
The approximately 2.212 kg of pure CaCO3 would be needed to neutralize the H+ in one year of acid rain on a 1-hectare site that received 1400 mm of rain per year with an average pH of 5.5.
How we can approximately CaCO3 neutralize H+ of rain per year with an average pH of 5.5.?To calculate the amount of pure CaCO3 needed to neutralize the H+ in one year of acid rain, we can use the following steps:
Calculate the total volume of water that falls on 1 hectare site in one year.1 hectare = 10,000 square metersTotal volume of rain = area x rainfallTotal volume of rain on 1 hectare = 10,000 m² x 1400 mmTotal volume of rain on 1 hectare = 14,000,000 liters or 14,000 m³Calculate the number of moles of H+ ions in the acid rain.pH is a logarithmic scale, so pH 5.5 means [H+] = 3.16 x 10⁻⁶ MNumber of moles of H+ ions in 14,000 m³ of rain = volume x concentrationNumber of moles of H+ ions in 14,000 m³ of rain = 14,000,000 L x 3.16 x 10⁻⁶ mol/LNumber of moles of H+ ions in 14,000 m³ of rain = 44.24 molesCalculate the amount of CaCO3 needed to neutralize the H+ ions.The balanced chemical equation for the reaction between CaCO3 and H+ is:CaCO3 + 2H+ → Ca2+ + CO2 + H2O
One mole of CaCO3 can neutralize 2 moles of H+ ions.Therefore, the amount of CaCO3 needed to neutralize 44.24 moles of H+ ions is:44.24 moles H+ x 1 mole CaCO3/2 moles H+ = 22.12 moles CaCO3Calculate the mass of CaCO3 needed to neutralize the H+ ions.The molar mass of CaCO3 is 100.09 g/mol.Therefore, the mass of CaCO3 needed to neutralize 22.12 moles of H+ ions is:22.12 moles CaCO3 x 100.09 g/mol = 2,212 g or 2.212 kgTherefore, approximately 2.212 kg of pure CaCO3 would be needed to neutralize the H+ in one year of acid rain on a 1-hectare site that received 1400 mm of rain per year with an average pH of 5.5.

Hydrogen and oxygen react to form water as shown in the reaction below. A mass of 7.2 grams of hydrogen is allowed to react completely with excess oxygen. However, the percent yield for this reaction is calculated to be only 90%, possibility due to an unknown experimental error. How many grams of water were actually formed in this reaction? (Please give your answer to 1 decimal place.)
H2 + O2 --> H2O
Answers
Taking into account definition of percent yield, 58.32 grams of water were actually formed.
Reaction stoichiometryIn first place, the balanced reaction is:
2 H₂ + O₂ → 2 H₂O
By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of moles of each compound participate in the reaction:
H₂: 2 moleO₂: 1 moleH₂O: 2 moleThe molar mass of the compounds is:
H₂: 2 g/moleO₂: 32 g/moleH₂O: 18 g/moleThen, by reaction stoichiometry, the following mass quantities of each compound participate in the reaction:
H₂: 2 moles ×2 g/mole= 4 gramsO₂: 1 mole ×32 g/mole= 32 gramsH₂O: 2 moles ×18 g/mole= 36 gramsPercent yieldThe percent yield is the ratio of the actual return to the theoretical return expressed as a percentage.
The percent yield is calculated as the experimental yield divided by the theoretical yield multiplied by 100%:
percent yield= (actual yield÷ theoretical yield)× 100%
where the theoretical yield is the amount of product acquired through the complete conversion of all reagents in the final product, that is, it is the maximum amount of product that could be formed from the given amounts of reagents.
Theoretical yield of H₂OThe following rule of three can be applied: if by reaction stoichiometry 4 grams of H₂ form 36 grams of H₂O, 7.2 grams of H₂ form how much mass of H₂O?
mass of H₂O= (7.2 grams of H₂× 36 grams of H₂O)÷ 4 grams of H₂
mass of H₂O= 64.8 grams
The theoretical yield of H₂O is 64.8 grams.
Actual yield of H₂O in this caseIn this case, you know:
percent yield= 90%actual yield= ?theorical yield= 64.8 gramsReplacing in the definition of percent yield:
90%= (actual yield÷ 64.8 grams)× 100%
Solving:
90%÷ 100%= actual yield÷ 64.8 grams
0.9= actual yield÷ 64.8 grams
0.9× 64.8 grams= actual yield
58.32 grams= actual yield
Finally, the actual yield of H₂O is 58.32 grams.

a) Determine the limiting reactant when 5.78 g of H2, and 6.28 g N2 are reacted to make NH3 you expect to get out of the chemical reaction.
Answers
Answer: nitrogen
Explanation:
Converting 5.78 g of hydrogen to moles, we know that the formula mass of hydrogen is about 2(1.00794)=2.01588 g/mol, so 5.78 grams is about 5.78/2.01588=2.867 mol.Converting 6.28 g of nitrogen to moles, we know that the formula mass of nitrogen is about 2(14.0067)=28.0134 g/mol, so 6.28 grams is about 6.28/28.0134 = 0.22417 mol.From the equation, we know that for every 3 moles of hydrogen consumed, 1 mole of nitrogen is consumed.
Considering the hydrogen, the reaction can occur 2.867/3=0.955 times.Considering the nitrogen, the reaction can occur 0.22417 times.Therefore, nitrogen is the limiting reactant.

How many grams of nitrogen gas are in a balloon with a volume of 35. 7 L at STP?
Answers
There are 44.62 grams of nitrogen gas in the balloon with a volume of 35.7 L at STP.
The volume of a balloon is 35.7 L at STP.
STP is the abbreviation for Standard Temperature and Pressure, which means a temperature of 273.15 K and a pressure of 101.325 kPa.
The number of grams of nitrogen gas in a balloon of this volume is requested.
A mole of any element has 6.02 × 1023 atoms, and the atomic mass of nitrogen is 14.01 grams.
One mole of a gas is equal to its molar volume, which is 22.4 L at STP. 1 mole of N2 gas = 28.02 g of N2 gas
STP's molar volume is 22.4 L, and the balloon's volume is 35.7 L.
That is, there are 35.7/22.4 moles of N2 gas in the balloon.= 1.59 moles of N2 gas
Since one mole of N2 gas weighs 28.02 g, 1.59 moles of N2 gas will weigh:
28.02 g/mol × 1.59 mol = 44.62 g
Therefore, there are 44.62 grams of nitrogen gas in the balloon with a volume of 35.7 L at STP.

Explanation:
Can you find if a substance is either pure k_2o or pure k_2o_2 when all you have is the mass of k?
Answers
Yes, the chemist can identify the substance in the sample.
When describing a compound's mass per mole, the term "molar mass" is employed. The molar mass is determined by multiplying the individual masses of all the atoms that make up a compound.
K₂O has a molar mass of 94.2 g/mol.
has a molar mass of 110.196 g/mol.
By multiplying the masses of each individual atom—one K atom weighs 39.0983 g/mol, whereas one O atom weighs 15.999 g/mol—the molar masses are obtained.
When the mass of a pure compound is known, the mass of oxygen (O) can be calculated by subtracting the mass of potassium (K) from the total mass. Since each of the mentioned compounds contain two K atoms, the difference in oxygen mass can be utilised to identify the pure chemical.
For instance, after deducting the mass of the K from the unknown molecule, the residual mass will be approximately 16 g if the compound is K₂O and approximately 32 g if the compound is K2O2.
