To solve this problem, we need to use stoichiometry. First, we need to balance the chemical equation:Fe + 6HCl --> FeCl3 + 3H2Now that the equation is balanced, we can proceed with the stoichiometry calculations.1. Determine the molar mass of Fe and H2.Fe: 55.85 g/molH2: 2.02 g/mol 1.01 g/mol for each H atom 2. Convert the mass of Fe to moles.10 g Fe * 1 mol Fe / 55.85 g Fe = 0.179 moles Fe3. Use the stoichiometry from the balanced equation to determine the moles of H2 produced.0.179 moles Fe * 3 moles H2 / 1 mole Fe = 0.536 moles H24. Convert the moles of H2 to grams.0.536 moles H2 * 2.02 g H2 / 1 mole H2 = 1.08 g H2So, 1.08 grams of H2 will be produced.
