c. reactants
d. energy

Answer 1

The original substances in a chemical equation are:

c. Reactant

Step-by-step explanation:

Reactants : The substance that are initially present in a chemical reaction and produce new compound (called products ).

Products : The substances produced after the reaction completes . here new bonds and species are formed

`A + B \rightarrow C +D`

A and B are originally present and called reactants

C and D are newly formed and called reactants

So original substance = Reactant

New Substance = Products
