Answer: D. Complete Combustion & Balanced
Step-by-step explanation:
D. Complete Combustion & Balanced
Complete combustion is a type of combustion reaction that occurs when a fuel reacts with oxygen to produce carbon dioxide and water as products. In a complete combustion reaction, the fuel is burned completely and all of the reactants in the reaction are used up.
A balanced reaction means that the number of atoms of each element on the reactant side of the equation is equal to the number of atoms of each element on the product side of the equation. The reaction shown above is balanced, meaning that there are 4 atoms of carbon and 8 atoms of oxygen on the reactant side, and 1 atom of carbon and 2 atoms of oxygen on the product side.
