Question

question 2 10 pts in the reaction 2 ba(no₃)₂(s)→δ 2 bao(s)+4 no₂(g)+o₂(g), barium nitrate is a: catalyst reactant reducing agent product

Explanation:

In a chemical - reaction equation, the substances on the left - hand side are reactants, and those on the right - hand side are products. A catalyst is not consumed in the reaction and is not part of the main reaction equation. A reducing agent donates electrons in a redox reaction. Here, barium nitrate ($Ba(NO_3)_2$) is on the left - hand side of the reaction equation, so it is a reactant.

Answer:

B. reactant
