There are approximately 6.02 × 10²³ atoms of phosphorus in one mole of 30.974 grams of phosphorus (option A).

<h3>How to calculate number of atoms?</h3>

The number of atoms of a substance can be calculated by multiplying the number of moles of the substance by Avogadro's number. That is;

no of atoms = no of moles × 6.02 × 10²³

According to this question, there are 30.974 grams of phosphorus in one mole of phosphorus. The number of atoms can be calculated as follows:

no of moles of P = 30.974g ÷ 31g/mol = 0.99mol

number of atoms = 0.99 mol × 6.02 × 10²³

number of atoms = 6.02 × 10²³ atoms

Therefore, there are approximately 6.02 × 10²³ atoms of phosphorus in one mole of 30.974 grams of phosphorus.

5. Some areas of the nation have limestone in the soil and lake bottoms. Explain how the presence of this mineral acts as a natu
mixer [17]

Limestone is calcium carbonate Ca(Co3) it's dissociation equation is as follows: Ca(CO3) <----> Ca+2 + CO3-2 

but the solubility is very small in the presence of acid by LeChatlier's Principle you can shift to the right by adding acid 

H+ + CO3-2 <-----> H+CO3- (the bicarbonate ion which is really soluble) 

The system will pull more and more limestone out into solution as acid is added and neutralize the acid coming from the rain.

What can be used to measure the ph of a substance
castortr0y [4]
The pH value can be measured using electrochemical measuring systems, litmus paper, or indicators and colorimeters. The easiest way to take a pH measurement is to use litmus paper or a colorimeter. The advantage of this type of pH measurement is that the pH range is well known and they are easy to apply.

<span>What are some examples of monomers and oligomers?
</span>Organic molecules, such as proteins, carbohydrates, lipids and nucleic acids, are made of simple subunits called monomers. <span>Plasticizers are </span>oligomeric esters widely used to soften thermoplastics such as PVC and <span>urethane acrylate </span>. 
<span>
</span><span>If a chemical compound accelerates and regulates metabolic reactions, which type of role does it play - structural or physiological? 
</span>I believe the function that it plays would be physiological since it focuses more on the regulation of the reactions inside the body.
