Answer:
The formulas of the reactants are C3H8 and O2. The formulas of the products are CO2 and H2O.
Step-by-step explanation:
Propane is the third member of the alkane group with the general formula CnH2n+2. According to this question, propane burns in oxygen to produce carbon dioxide and water. This means that propane and oxygen are the reactants of this reaction while carbon dioxide and water are the products.
The chemical formulas of the respective reactants and products are as follows:
REACTANTS:
Propane = C3H8 i.e C3H(2×3)+2
Oxygen = O2
PRODUCTS:
Carbon dioxide = CO2
Water = H2O
The balanced chemical reaction is as follows:
C3H8 + 5O2 ----> 3CO2 + 4H2O
