Answer:
The total mass of the products (10 g) is indeed equal to the total mass of the reactant (100 g). This demonstrates that mass is conserved in the chemical reaction. The law of conservation of mass is upheld, indicating that the total mass of the substances involved remains constant before and after the chemical change. Therefore, the observations are in agreement with this fundamental scientific principle.
To show that these observations are in agreement with the law of conservation of mass, we need to calculate the total mass of the products and compare it to the total mass of the reactant. According to the law of conservation of mass, the total mass of the products should be equal to the total mass of the reactant.
Here's how to demonstrate this:
Calculate the total mass of the products:
Mass of carbon dioxide (CO₂) produced = 4.4 g
Mass of calcium oxide (CaO) produced = 5.6 g
Total mass of products = Mass of CO₂ + Mass of CaO
Total mass of products = 4.4 g + 5.6 g = 10 g
Calculate the total mass of the reactant:
Mass of calcium carbonate (CaCO₃) = 100 g
Compare the total mass of the products to the total mass of the reactant:
Total mass of products (10 g) = Total mass of reactant (100 g)
