What is a balanced equation for the combustion of gaseous ethane (#C_2H_6#), a minority component of natural gas, in which it combines with gaseous oxygen to form gaseous carbon dioxide and gaseous water?

Answer 1

The balanced equation for the combustion of gaseous ethane (C2H6) combining with gaseous oxygen to form gaseous carbon dioxide and gaseous water is:

[ 2C_2H_6(g) + 7O_2(g) \rightarrow 4CO_2(g) + 6H_2O(g) ]

#C_2H_6(g) + 7/2O_2(g) rarr 2CO_2(g) +3H_2O(g)#

One equivalent of ethane reacts with seven and a half equivalents of dioxygen gas to produce two equivalents of carbon dioxide and three equivalents of water. You can double the equation if you'd like.

What is the reaction's energy transfer mechanism? Is it endothermic or exothermic?

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
