Accepted Answer

∻Solution∻ ‖ 1 ⋮ **Identify the reactants**: The reaction involves ammonium chloride ($NH_4Cl$) and sodium hydroxide ($NaOH$). ‖ ‖ 2 ⋮ **Write the chemical equation**: The reaction between $NH_4Cl$ and $NaOH$ can be represented by the equation: $NH_4Cl_{(aq)} + NaOH_{(aq)} \rightarrow NaCl_{(aq)} + H_2O_{(l)} + NH_3_{(g)}$. ‖ ‖ 3 ⋮ **Predict the evidence of reaction**: From the equation, we can predict that there will be a change in odor due to the formation of ammonia gas ($NH_3$), which has a distinct smell. ‖ ‖ 4 ⋮ **Eliminate other options**: There is no inherent reason for a temperature decrease, color change, or precipitate formation in this reaction. ‖ ∻Answer∻ ⚹ c) Change in odor ⚹ ∻Key Concept∻ ⚹ Evidence of a chemical reaction ⚹ ∻Explanation∻ ⚹ The formation of ammonia gas, which has a characteristic odor, is evidence of the reaction between $NH_4Cl$ and $NaOH$. ⚹◊What is the chemical equation for the reaction between NH$_4$Cl and NaOH that results in the formation of a precipitate?⍭ Generate me a similar question◊
