Question

C2H4 + O2 → 2C + 2H2O Mg + H2O → MgO + H2 N2 + 2O2 → 2NO2 S + O2 → S + H2O

Which of the following is a valid combustion reaction?

Answer 1

N₂ + 2O₂ → 2NO₂

Step-by-step explanation:

it's an inorganic compound

Answer 2

N₂ + 2O₂ → 2NO₂

Step-by-step explanation:

• A combustion reaction in which substances burn completely or partially in presence of oxygen gas.
• In this case the valid combustion reaction is;

N₂(g) + 2O₂(g) → 2NO₂(g)

• The reaction shows the combustion of nitrogen gas in air to produce nitrogen (IV) oxide.
• Other type of chemical reactions include precipitation reactions, decomposition reactions, synthesis reactions, single and double replacement reactions among others.
