You are performing a chemical reaction. The mass of reactant 1 is 24 grams. The mass of reactant 2 is 39 grams. The reaction forms a solid and a gas. The mass of the solid is 44 grams. What is the mass of the gas? Answer choices: 19, 33, 0, 5.

Answer 1

To find the mass of the gas produced in the reaction, we can use the principle of conservation of mass. According to this principle, the total mass of the reactants must equal the total mass of the products.

1. Calculate the total mass of the reactants:

   • Mass of reactant 1 = 24 grams
   • Mass of reactant 2 = 39 grams
   • Total mass of reactants = 24 + 39 = 63 grams

2. The products of the reaction include a solid and a gas:

   • Mass of the solid = 44 grams
   • Let the mass of the gas be \( x \) grams.

3. According to the conservation of mass: \[ \text{Total mass of reactants} = \text{Mass of solid} + \text{Mass of gas} \] \[ 63 = 44 + x \]

4. Solving for \( x \): \[ x = 63 - 44 \] \[ x = 19 \]

Thus, the mass of the gas produced is 19 grams.

Therefore, the answer is 19.
