The following demonstration takes place in a two-step process: First, solid calcium carbide $\left(\mathrm{CaC}_{2}\right)$ reacts with liquid water to produce acetylene gas $\left(\mathrm{C}_{2} \mathrm{H}_{2}\right)$ and aqueous calcium hydroxide. Second, the acetylene gas produced is then ignited with a match, causing the combustion reaction of acetylene with oxygen gas to produce gaseous carbon dioxide and gaseous water. Write the balanced equation for each reaction that is occurring.

Key Concepts

Hydrolysis Reaction

A hydrolysis reaction involves the chemical breakdown of a compound due to its interaction with water. In many cases, water acts as both a reactant and a medium that facilitates the breaking of chemical bonds, resulting in products that differ significantly in structure and composition from the original compound.

Reaction Balancing

Reaction balancing is the process of ensuring that the number of atoms for each element is equal on both the reactant and product sides of a chemical equation. This fundamental principle adheres to the conservation of mass, requiring careful adjustment of stoichiometric coefficients while accounting for all atoms, charge, and sometimes phase changes in the reaction.

Combustion Reaction

A combustion reaction is an exothermic chemical process in which a substance reacts rapidly with oxygen to produce oxidized products, typically including carbon dioxide and water when a carbon-based fuel is involved. This type of reaction is characterized by the release of energy in the form of heat and light and is fundamental in various practical applications, such as energy production and propulsion.
