What are reactants in a chemical reaction?
Answer and explanation
Correct answer: The starting substances that take part in a reaction to form products
Reactants are the starting substances that undergo chemical change and form products. In a chemical equation, they are conventionally written on the left side of the arrow; for example, in 2H₂ + O₂ → 2H₂O, hydrogen and oxygen are reactants. The new substances on the right are products, while a substance that changes reaction rate is a catalyst.
