Determine the type of reaction for the following equation:<br> C2H6 + O2à H2O + CO2

valkas [14]

Answer:

The type of reaction for the following equation is combustion equation.

Explanation:

Combustion reaction is defined as the chemical reaction in which a hydrocarbon reacts with oxygen gas to produce carbon dioxide gas and water molecule.

$\text{hydrocarbon}+O_2\rightarrow CO_2+H_2O$

The reaction given to us:

$C_2H_6 + \frac{7}{2}O_2\rightarrow 3H_2O + 2CO_2$

When 1 mole of ethane reacts with 7/2 moles of oxygen gas it gives 3 moles of water and 2 moles of carbon dioxide gas.

The type of reaction for the following equation is combustion equation.
