Hey Engr, good to see you again. Let's solve this chemistry problem. Step 1: Write the balanced chemical equation. The reaction between hydrogen and oxygen produces water. 2H₂(g) + O₂(g) → 2H₂O(l) Step 2: Calculate the moles of hydrogen (H₂). We'll use the molar masses: H = 1 g/mol, O = 16 g/mol. Molar mass of H₂ = 2 × 1 g/mol = 2 g/mol Moles of H₂ = Mass / Molar mass Moles of H₂ = 8.0 g / 2 g/mol Moles of H₂ = 4.0 mol Step 3: Use the mole ratio from the balanced equation to find moles of water. From the balanced equation, 2 moles of H₂ produce 2 moles of H₂O. This is a 1:1 mole ratio. Moles of H₂O = Moles of H₂ Moles of H₂O = 4.0 mol Step 4: Calculate the mass of water (H₂O) produced. Molar mass of H₂O = (2 × 1 g/mol) + 16 g/mol = 18 g/mol Mass of H₂O = Moles × Molar mass Mass of H₂O = 4.0 mol × 18 g/mol Mass of H₂O = 72 g The mass of water produced is 72 g. Send me the next one 📸
