When the equation #C_2H_4+O_2 -> CO_2+H_2O# is balanced using smallest whole numbers, what is the coefficient of the #O_2#?

Answer 1

#C_2H_4(g) + 3O_2(g) rarr 2CO_2(g) + 2H_2O(l)#

The answer is #3#. Is this balanced? For every reactant particle, is there a corresponding product particle? There are #2C# reactant particles, and #2C# product particles. You have to count up the number of remaining hydrogen and oxygen reactant particles, and see if these correspond to the number of hydrogen and oxygen product particles.

In the event that these figures diverge, you can be certain that the response is out of balance and hence not in line with reality.

The coefficient of O2 in the balanced equation C2H4 + O2 -> CO2 + H2O is 3.

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.
