Balance the following reaction. 2Ca3(PO4)2 + C + 6SiO2 → CaSiO3 + P4 + CO
miskamm [114]

Answer:

2Ca₃(PO₄)₂ + 10C + 6SiO₂ → 6CaSiO₃ + P₄ + 10CO.

Explanation:

  • To balance a chemical reaction, we should apply the law of conservation of mass.

  • Law of conversation of mass states that the no. of atoms is equal in both sides of the chemical reaction.

  • So, the balanced chemical reaction is:

<em>2Ca₃(PO₄)₂ + 10C + 6SiO₂ → 6CaSiO₃ + P₄ + 10CO.</em>

that 2 mol of Ca₃(PO₄)₂ react with 10 mol of C and  6 mol of SiO₂ to produce 6 mol of CaSiO₃, 1 mol of P₄ and 10 mol of CO.
