kramer

Answer:

5SiO2 + 2CaC2 ➡ 5Si + 2CaO + 4CO2

Explanation:

This question involves balancing the above equation. An equation is said to be BALANCED when all the atoms of each element in the reactant side equates that in the product side.

According to this question, a chemical reaction is given as follows: SiO2 + CaC2 = Si + CaO + CO2. Based on observation, the atoms of elements are Silicon, oxygen, calcium and carbon are not the same on the reactants and products side. Based on this, the balanced equation is:

5SiO2 + 2CaC2 ➡ 5Si + 2CaO + 4CO2
