Question

Which one of these is a proper complete combustion reaction?

a) C2H4(g) + O2(g) → CO2(g) + 2H2(g) + A

b) C2O4(g) + H2(g) → CH2(g) + 2CO2(g) + A

c) C2H4(g) + O2(g) → CO2(g) + 2H2O(g) + A

d) C2H4(g) + O2(g) → CO2(g) + 2H2O(l) + A

Answer 1

The proper complete combustion reaction is represented by the equation C2H4(g) + O2(g) → CO2(g) + 2H2O(g).

Step-by-step explanation:

In this question, we are given four chemical equations and we need to determine which one represents a proper complete combustion reaction. A complete combustion reaction occurs when a fuel reacts with an oxidant (usually oxygen) to produce carbon dioxide and water as the only products. When we examine each equation, we find that option c) C2H4(g) + O2(g) → CO2(g) + 2H2O(g) is the only one that represents a complete combustion reaction because it produces carbon dioxide and water as the only products.
