The correct Answer is:
To solve the question regarding the gas evolved when ammonium dichromate \((NH_4)_2Cr_2O_7\) is heated, we can follow these steps: ### Step 1: Identify the Compound The compound given is ammonium dichromate, which has the formula \((NH_4)_2Cr_2O_7\). ### Step 2: Understand the Reaction When ammonium dichromate is heated, it undergoes a decomposition reaction. This means that the compound breaks down into simpler substances. ### Step 3: Write the Decomposition Reaction The decomposition of ammonium dichromate can be represented by the following chemical equation: \[ (NH_4)_2Cr_2O_7 \rightarrow Cr_2O_3 + N_2 + H_2O \] In this reaction, ammonium dichromate decomposes to form chromium(III) oxide (\(Cr_2O_3\)), nitrogen gas (\(N_2\)), and water vapor (\(H_2O\)). ### Step 4: Identify the Gases Produced From the balanced equation, we can see that nitrogen gas (\(N_2\)) and water vapor (\(H_2O\)) are produced. However, since the question specifically asks for the gas evolved, we focus on nitrogen gas. ### Step 5: Conclude the Answer Thus, the gas evolved when ammonium dichromate is heated is nitrogen gas (\(N_2\)). ### Final Answer The gas evolved is nitrogen gas (\(N_2\)). ---
