Question

What is the mass of the missing material in the following equation? _____ g carbonic acid → 22.0 g CO₂ + 9.0 g H₂O A)13.0 g B)29.0 g C)31.0 g D)62.0 g

Quizplus · Accepted Answer

The law of conservation of mass states that mass is neither created nor destroyed in a chemical reaction. Therefore, the mass of the reactants must equal the mass of the products. The total mass of the products is 22.0 g + 9.0 g = 31.0 g. Thus, the mass of the missing carbonic acid must be 31.0 g.
