This is the equation for the combustion of propane.
c3h8 + 5o2 → 3co2 + 4h2o + heat
which are the reactants and the products in this reaction?
a.
the reactants are c3h8 (propane) and h2o (water). the products are o2 (oxygen) and co2 (carbon dioxide).
b.
the reactants are c3h8 (propane) and o2 ( oxygen). the products are co2 (carbon dioxide) and h2o (water).
c.
the reactants are co2 (carbon dioxide) and h2o (water). the products are c3h8 (propane) and o2 ( oxygen).
d.
the reactants are o2 (oxygen) and co2 (carbon dioxide). the products are c3h8 (propane) and h2o (water).

B

Explanation:

Reactants are the compounds which reaction produce the products. In general terms this can be expressed symbolically as follows:

reactants -> products

Other phenomena like heat are omitted because are not always present, that is, only compounds are included. Therefore, in this reaction the reactants are C3H8 (propane) and O2 ( oxygen) and the products are CO2 (carbon dioxide) and H2O (water)

Explanation:

Balancing Carbon atoms on the right side,

Balancing Hydrogen atoms on the right side,

Balancing Oxygen atoms on the left side,

The reactants are on the left side of the reaction:

Propane and oxygen are the reactants.

The products are on the right side of the reaction:

Carbon dioxide and water are the products.

it is b that is the answer.
