Question

............. EQUATIONS CAN BE USED TO REPRESENT CHEMICAL REACTIONS.

Answer 1

Answer:

In mathematic equations we use an equal sign (=) for example 2 + 2 = 4, but in scientific chemical equations, we use an arrow (→), for example C + O2→ CO2. To the left of the arrow, we have the 'before' situation. This side represents the substances we have beforethe reaction takes place. They are called the reactants.
