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

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.

Answer: The balanced chemical equation is given below.

Explanation:

A balanced chemical equation is defined as the equation in which total mass of the reactants is equal to the total mass of the products. The number of individual atoms on the reactant side is equal to the number of individual atoms on the product side. These equations follow Law of conservation of mass.

The balanced chemical equation for the reaction of phosphorous and chlorine gas follows:

[tex]P_4(s)+6Cl_2(g)\rightarrow 4PCl_3(g)[/tex]

By Stoichiometry of the reaction:

1 mole of solid phosphorus reacts with 6 moles of chlorine gas to produce 4 moles of phosphorus trichloride gas.
