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 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.

answer:

the reaction is type of combination reaction.

explanation:

on the product side, there are 2 molecules of bonded to fe   which means one atom of fe are combined two molecules of . so, balanced chemical equation becomes :

this reaction follows the reaction type of combination reaction. a combination reaction is defined as chemical reaction in which reactants combines together to form a single product.
