Identify the reactants: Ammonium iodide \((\text{NH}_4\text{I})\) and sodium hydroxide \((\text{NaOH})\).
Recognize that \(\text{NH}_4^+\) from \(\text{NH}_4\text{I}\) will react with \(\text{OH}^-\) from \(\text{NaOH}\) to form ammonia gas \((\text{NH}_3)\) and water \((\text{H}_2\text{O})\).
Write the unbalanced equation: \(\text{NH}_4\text{I} + \text{NaOH} \rightarrow \text{NH}_3 + \text{H}_2\text{O} + \text{NaI}\).
Balance the equation by ensuring the number of each type of atom is the same on both sides of the equation.
Verify that the equation is balanced by checking that the total charge and the number of each type of atom are equal on both sides.

Ecco i concetti essenziali che devi comprendere per rispondere correttamente alla domanda.
Gas-Evolution Reactions
Gas-evolution reactions are chemical reactions that produce a gas as one of the products. These reactions often involve the combination of an acid and a base, leading to the formation of a gas, water, and a salt. Understanding the types of gases produced, such as carbon dioxide or ammonia, is crucial for predicting the outcome of the reaction.

Balancing Chemical Equations
Balancing chemical equations is the process of ensuring that the number of atoms for each element is the same on both sides of the equation. This is based on the law of conservation of mass, which states that matter cannot be created or destroyed in a chemical reaction. Proper balancing is essential for accurately representing the stoichiometry of the reaction.
