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.
