🤓 Based on our data, we think this question is relevant for Professor Cook's class at OKSTATE.
In this problem, we are asked to define a gas-evolution reaction.
A gas evolution reaction is a chemical process that produces a gas, such as oxygen or carbon dioxide.
For example, an acid i.e. nitric acid (HNO3) reacts with a carbonate i.e sodium carbonate (Na2CO3), producing salt, carbon dioxide, and water.
