Balance the equation

Answer: Balanced chemical equation will be :
[tex]5SiO_2+2CaC_2\rightarrow 5Si+2CaO+4CO_2[/tex]
Explanation:
[tex]SiO_2+CaC_2\rightarrow Si+CaO+CO_2[/tex](Unbalanced)
A balanced chemical reaction follows the Law of Conservation of Mass. which states in a chemical reaction mass can neither be created nor be destroyed. In other words total mass of the products is equal to the total mass of reactants.
Balanced chemical equation will be :
[tex]5SiO_2+2CaC_2\rightarrow 5Si+2CaO+4CO_2[/tex]
