Question

Is Ca + O --> CaO a balanced chemical equation? Is it obeying the law of conservation of matter? Question 5 options: Yes it is balanced. It has the same number of Ca and O on both the reactant side and the product side. No it is not balanced. It has more Ca on the product side than the reactant side. No it is not balanced it has more O on the reactant side than the product side.

Answer 1

Answer is: Yes it is balanced. It has the same number of Ca and O on both the reactant side and the product side.

According to principle of mass conservation, number of atoms must be equal on both side of chemical reaction.

There is one calcium atom atom and one oxygen atom on both side of reaction, so chemical reaction is balanced.
