What is a chemical reactant in a chemical reaction?

Answer 1

A reactant is the starting material of a reaction.

For example, in the reaction 2H(+) + O(2-) --> H2O, both H(+) ions and the O(-) ion are the reactants, whereas H2O is the product of the reaction.

A reactant is something that REACTS.

Answer 2

A chemical reaction occurs because the reactant(s), that is the elements or compounds that are reacting, undergo a change in the way the atoms are joined together.

A reactant is the product(s) that you started with before a chemical change took place.

(ie. they are reacting together, hence why they are called reactants.)

(Ex.) The chemical reactants are in bold, in the following skeleton equation:

Pb(NO3)2+ KI

-------------->KNO3 + PbI2

Anotherexample, as such:

HgO

-------------------

à

Hg + O2

**Notice in this chemical reaction, there is only one reactant.

Just remember:

Reactant(s) -----------> Products

Answer 3

A chemical reactant is a substance that undergoes transformation into one or more new substances during a chemical reaction. It is typically found on the left side of a chemical equation.

Answer 4

In any chemical reaction you start out with certain chemicals which are called the reactants, and they then react and turn into other chemicals which are called the products.
