When calcium carbonate (CaCO₃) decomposes, it produces calcium oxide (CaO) and carbon dioxide (CO₂) according to the following balanced chemical equation:
\[ \text{CaCO}_3 (s) \rightarrow \text{CaO} (s) + \text{CO}_2 (g) \]
From the equation, you can see that 1 mole of calcium carbonate produces 1 mole of carbon dioxide.
Therefore, if you start with 2.5 moles of calcium carbonate (CaCO₃), it will produce an equal number of moles of carbon dioxide (CO₂):
\[
\text{Moles of CO}_2 = 2.5 \text{ moles of CaCO}_3 \times \frac{1 \text{ mole of CO}_2}{1 \text{ mole of CaCO}_3} = 2.5 \text{ moles of CO}_2
\]
So, 2.5 moles of calcium carbonate will produce **2.5 moles of carbon dioxide (CO₂)**.
\[ \text{CaCO}_3 (s) \rightarrow \text{CaO} (s) + \text{CO}_2 (g) \]
From the equation, you can see that 1 mole of calcium carbonate produces 1 mole of carbon dioxide.
Therefore, if you start with 2.5 moles of calcium carbonate (CaCO₃), it will produce an equal number of moles of carbon dioxide (CO₂):
\[
\text{Moles of CO}_2 = 2.5 \text{ moles of CaCO}_3 \times \frac{1 \text{ mole of CO}_2}{1 \text{ mole of CaCO}_3} = 2.5 \text{ moles of CO}_2
\]
So, 2.5 moles of calcium carbonate will produce **2.5 moles of carbon dioxide (CO₂)**.
