Phosphorus trichloride gas is obtained by the reaction of chlorine gas and solid phosphorus . write a balanced chemical equation for this reaction.

The answer is:

2P + 3Cl2 +Heat °c→ 2PCl3

The explanation:

when the chemical formula of the phosphorus is (P) and the chemical formula of the chlorine (Cl) and the phosphorus trichloride chemical formula is PbCl3

So, the chemical equation is:

P + Cl2 +Heat °c→ PCl3

but this is not a balanced chemical equation so, we will start to balance it:

we have 3 atoms of Cl on the right side and 2 atoms on the left side so, we need to make them equal on both sides.

so we will but 3 on the left side it will become 3Cl2 instead of Cl2

then will put 2 on the right side, it will become 2pCl3

now the atoms number of Cl are equal on both sides, but we need to make p atoms equal too. so, we will put 2 on the left side so, it will be :

2P + 3Cl2 +Heat °c → 2PCl3

and this is the final balanced equation for the reaction.

yes yes yes yes yes yes yes yes yes yes yes yes yes yes yes

explanation:

- 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
