Ethane burning in oxygen to give carbon dioxide and steam. The volume ratio of reactants to products is ______________.

Q. Assuming all volumes measured at the same temperature and pressure, state the volume ratio of the reactants and products when ethane burning in oxygen to give carbon dioxide and steam.

Q. Assuming all volumes measured at the same temperature and pressure, state the volume ratio of the reactants and products when acetylene (ethyne) burning in oxygen to give carbon dioxide and steam.

Q. A welding fuel gas contains carbon and hydrogen only. Burning a small sample of it in oxygen gives 3.38 g carbon dioxide, 0.690 g of water and no other products. A volume of 10.0 L (measured at STP) of this welding gas is found to weigh 11.6 g. Choose the correct molecular formula of the gas.

Q. Ethane$\left(C_2{H}_6\right)$ reacts with oxygen gas to produce carbon dioxide and water. Initially,
5 mol of ethane is burned with 16 mol of oxygen, find the amount of carbon dioxide produced when the yield of the reaction is 60 %.
$2C_2{H}_6+7O_2\to 4C{O}_2+6H_{2}O$

Q. A welding fuel gas contains carbon and hydrogen only. Burning a small sample of it in oxygen gives 3.38 g carbon dioxide, 0.690 g of water and no other products. A volume of 10.0 litre (measured at STP) of this welding gas is found to weigh 11.6 g. Calculate molecular formula of gas.
