Question

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

60 grams

30 grams

Explanation:

Step1: Apply the law of conservation of mass

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

Step2: Analyze the given reaction

In the reaction \(CaCO_{3}\to CO_{2}+CaO\), the reactant is \(CaCO_{3}\) with a mass of \(30\) grams.

Answer:

30 grams
