8.4 g of sodium bicarbonate on reaction ...

8.4 g of sodium bicarbonate on reaction with 20 g of acetic acid liberated 4.4 g of carbon dioxide gas into the atmosphere. What is the mass of the residue left?

Text Solution

AI Generated Solution

To solve the problem, we will use the principle of conservation of mass, which states that the mass of the reactants is equal to the mass of the products. ### Step-by-Step Solution: 1. **Identify the Mass of Reactants**: - Sodium bicarbonate (NaHCO₃) = 8.4 g - Acetic acid (CH₃COOH) = 20 g - Total mass of reactants = 8.4 g + 20 g = 28.4 g ...
