Answer:

I hope it helps u

Explanation:

The advantages of using natural gas rather than coal are the following,

  • Natural gas is present in large amount than coal.
  • Natural gas is less costly than other fossil fuel sources of energy.
  • It increases security by decreasing dependence.
  • Natural gas is more environmentally friendly.
  • Natural gas is much safer to store.
  • It is reliable.
  • Natural gas is a fossil fuel, though the global warming emissions from its combustion are much lower than those from coal or oil.
  • Natural gas emits 50 to 60 percent less carbon dioxide (CO2) when combusted in a new, efficient natural gas-power plant compared with emissions from a typical new coal plant.

60g ethane requires 7x32= 224g oxygen

here ethane is in excess.oxygen will be fully consumed

hence

300g oxygen will consume  

60

⋅

300

224

=

80.36

g

ethane

leaving (270-80.36)= 189.64 g ethane.

By the Balanced eqn

60g ethane produces 4x44 g CO2

hence amount of CO2 produced =

⋅

44

⋅

80.36

and its no. of moles will be

=5.36 where 44 is the molar mass of Carbon dioxide

hope this helps
