Question

What are the resulting coefficients when you balance the chemical equation for the combustion of ethane, C2H6? In this reaction, ethane is burned in the presence of oxygen (O2) to form carbon dioxide (CO2) and water (H2O). ____C2H6(g)+____O2(g)→____CO2(g)+____H2O(g)

Answer 1

Answer: The coefficients for balancing the given chemical equation are 2, 7, 4 and 6

Step-by-step explanation:

Every balanced chemical equation follows law of conservation of mass.

This law states that mass can neither be created nor be destroyed, but it can only be transformed from one form to another form. This also means that total number of individual atoms on the reactant side must be equal to the total number of individual atoms on the product side.

The given balanced chemical equation follows:

`2C_2H_6+7O_2\rightarrow 4CO_2+6H_2O`

On reactant side:

Number of carbon atoms = 4

Number of hydrogen atoms = 12

Number of oxygen atoms = 14

On product side:

Number of carbon atoms = 4

Number of hydrogen atoms = 12

Number of oxygen atoms = 14

Hence, the coefficients for balancing the given chemical equation are 2, 7, 4 and 6
