Q
Q: What is the total number of moles of gas produced when 1 mole of CaCO3 decomposes?
Solution:
The decomposition of CaCO3 produces CaO and CO2: CaCO3 → CaO + CO2. This results in 1 mole of gas (CO2) being produced.
Steps: 5
Show Steps
Step 1: Identify the chemical reaction for the decomposition of calcium carbonate (CaCO3).
Step 2: Write the balanced equation: CaCO3 → CaO + CO2.
Step 3: Look at the products of the reaction. We have CaO (solid) and CO2 (gas).
Step 4: Count the number of moles of gas produced. In this case, there is 1 mole of CO2.
Step 5: Conclude that the total number of moles of gas produced is 1 mole.
