Carlos is making phosphorus trichloride using the equation below. He uses 15.5 g of phosphorus and collects 50.9 g of phosphorus chloride.

2P +3Cl2 → 2PCl3

How much chlorine reacted with the phosphorus?

Answer : The mass of chlorine reacted with the phosphorus is, 53.25 grams.

Explanation :

First we have to calculate the moles of phosphorus.

Now we have to calculate the moles of

The balanced chemical reaction is:

From the balanced chemical reaction, we conclude that

As, 2 moles of phosphorous react with 3 moles of

So, 0.5 moles of phosphorous react with moles of

Now we have to calculate the mass of

Molar mass of = 71 g/mol

Therefore, the mass of chlorine reacted with the phosphorus is, 53.25 grams.

- calcium has greater affinity to bond with electron receptors than hydrogen does and hence, it has the ability to replace hydrogen in most of its compounds.

- lithium has 2 valence electrons in the product because it can make only 1 bond with hydrogen. beryllium has 4 valence electrons in the product because it can only make 2 bonds. it has fewer electrons than neon and can react with electron donors. each hydrogen has 2 valence electrons, the same as helium.

- the covalent bond formed between carbon and hydrogen is polar because carbon is more electronegative than hydrogen and it attracts the bonded electron pair closer to itself, thus giving hydrogen a partial positive charge.

- a hydrogen bond is a relatively weak bond that hydrogen atoms make with the electronegative atoms nitrogen, oxygen or fluorine.

so the best choice is a.) 2 calcium (ca) atoms
