Question

Is the law of conservative mass observed in this equation CaCO3 + 2HCI -->CaCI2 +H2O + CO2

Answer 1

Answer:

The law is observed in the given equation.

Explanation:

CaCO₃ + 2HCI → CaCI₂ +H₂O + CO₂

In order to find out if the law of conservative mass is followed, we need to count how many atoms of each element are there in both sides of the equation:

• Ca ⇒ 1 on the left, 1 on the right.

• C ⇒ 1 on the left, 1 on the right.

• O ⇒ 3 on the left, 3 on the right.

• H ⇒ 2 on the left, 2 on the right.

• Cl ⇒ 2 on the left, 2 on the right.

As the numbers for all elements involved are the same, the law is observed in the given equation.
