Enter a balanced equation for the combustion of gaseous ethane (c2h6), a minority component of natural gas, in which it combines with gaseous oxygen to form gaseous carbon dioxide and gaseous water. express you answer as a chemical equation including phases.

The balanced chemical equation for the combustion of gaseous ethane (C2H6) is given by;  

2C2H6(g) + 7O2(g) --> 4CO2(g) + 6H2O(g)

C2H6 and O2 are the reactants while CO2 and H2O are the products.

2C2H6(g) + 7O2(g) --> 4CO2(g) + 6H2O(g)

It is balanced with; 4 carbon atoms, 14 oxygen atoms, and 12 hydrogen atoms .Ethane, oxygen, carbon dioxide and water, all are in gaseous state.

as given the equation is

2al + 6 hcl > 2 alcl3 + 3 h2(g)

as per equation two moles of aluminum reacts with six moles of hcl to give two moles of alcl3 and three moles of hydrogen gas

given: three moles of al are present and 7 moles of hcl

for three moles of aluminum nine moles of hcl will be required

however as 7 moles of hcl are present so the limiting reagent is hcl

hcl is going to decide the number of moles of product formed

when six moles of hcl are present = 3 moles of h2 are formed

when one mole of hcl is present == 3/6 mole sof h2 will be formed

when 7 moles of hcl are present = 3 x 7/ 6 moles of h2 will be formed = 3.5 moles of h2
