Question

Quizplus · Accepted Answer

The decomposition of carbonic acid (H2CO3) into water (H2O) and carbon dioxide (CO2) can be represented by the balanced chemical equation: H2CO3 → H2O + CO2. To find how much CO2 is formed from 1.55 g of H2CO3, we first calculate the molar mass of H2CO3 (2*1.01 + 12.01 + 3*16.00 = 62.03 g/mol) and CO2 (12.01 + 2*16.00 = 44.01 g/mol). Using the stoichiometry of the reaction, 1 mole of H2CO3 produces 1 mole of CO2. Therefore, (1.55 g H2CO3 / 62.03 g/mol H2CO3) * 44.01 g/mol CO2 = 1.10 g CO2.
