Question

chemical reactions quick check
use the chemical reaction to answer the question.
caco₃ → co₂ + cao
a scientist heats 30 grams of calcium carbonate (caco₃) in the chemical reaction shown. what is the total mass of the products?
(1 point)
15 grams
10 grams
30 grams
60 grams

Explanation:

Step1: Apply the law of conservation of mass

The law of conservation of mass states that in a chemical reaction, the mass of the reactants is equal to the mass of the products.

Step2: Identify reactant and products

Here, the reactant is \(CaCO_3\) with a mass of \(30\) grams. The products are \(CO_2\) and \(CaO\).

Answer:

30 grams
