Question

Balance this compound

Answer 1

This should be what you need to have it balanced

Answer 2

Answer: The balanced chemical equation is given by,

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

Explanation:

$C_2H_6+O_2\rightarrow CO_2+H_2O$

Law of conservation of mass 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 mass on the reactant side must be equal to the total mass on the product side.

So, the balanced chemical equation is given by, will writing stoichiometric coefficient 2 in front of ethane , 7 in front of oxygen , 4 in front of carbon dioxide gas and 6 in front of water.

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

According to reaction, 2 moles of ethane reacts with 7 moles of oxygen to give 4 moles f carbon dioxide gas and 6 moles of water.
