1) This equation describes the synthesis of ammonia: PRACTICE PROBLEMS 00 N2(g) + 3H2(g) → 2NH3(8) a) Prove the law of conservation of mass using the particle model for the chemical change represented above. Legend: Nitrogen 00 N₂+ 3H₂→ 2NH3 => Balanced 2) If 56g of nitrogen (N₂) is combined with hydrogen (H₂) and 68g of ammonia (NH3 ) is produced, what mass of hydrogen was used? N₂ + 3H₂ → 2NH3 68g 569 N: 2 N: 2 ✓ H: 6✓ H:6 V Mass of hydrogen = 68-56 =129 o= Hydrogen 0= ✓
