Q: What is the total number of moles of gas produced when 1 mole of CaCO3 decomposes to form CaO and CO2?
Solution:
The decomposition reaction is CaCO3 → CaO + CO2. This produces 1 mole of CaO and 1 mole of CO2, totaling 2 moles of gas.
Steps: 4
Show Steps
Step 1: Write down the decomposition reaction: CaCO3 → CaO + CO2.
Step 2: Identify the products of the reaction. Here, we have CaO and CO2.
Step 3: Count the moles of each product. We get 1 mole of CaO and 1 mole of CO2.
Step 4: Add the moles of gas produced. 1 mole of CaO + 1 mole of CO2 = 2 moles of gas.
