Final answer:
When 50 grams of calcium carbonate is heated, 28 grams of calcium oxide is produced. This is determined using the ratio from a given example where 10 grams of calcium carbonate yields 5.6 grams of calcium oxide.
Step-by-step explanation:
The question revolves around a chemical reaction where calcium carbonate (CaCO3) is heated to produce calcium oxide (CaO) and carbon dioxide (CO2). The decomposition of calcium carbonate is represented by the equation:
CaCO3 → CaO + CO2
From the provided examples, we know that heating 10 grams of CaCO3 produces 5.6 grams of CaO. Thus, the ratio of the mass of CaCO3 to the mass of CaO produced is 10:5.6. Using this ratio, we can calculate the amount of CaO produced from 50 grams of CaCO3.
Calculation:
- 50 grams CaCO3 x (5.6 grams CaO / 10 grams CaCO3) = 28 grams CaO
Therefore, the correct answer to the question of how much calcium oxide is produced when 50 grams of calcium carbonate is heated is 28 grams (Option B).
