here are the complete solutions for deciphering the equations: a) Step 1: Identify reactants and products from the model using the key. Reactants: One black circle (Carbon, C) and two molecules of two white circles (Hydrogen, 2H₂). Products: One molecule of one black circle bonded to four white circles (Methane, CH₄). i) Word equation: Carbon + Hydrogen → Methane ii) Chemical equation: C + 2H₂ → CH₄ b) Step 1: Identify reactants and products from the model using the key. Reactants: One green circle (Chlorine, Cl) and one molecule of one purple circle bonded to four white circles (Potassium tetrahydride, KH₄). Products: One molecule of one green circle bonded to two white circles (Dihydrogen chloride, ClH₂), one molecule of one purple circle bonded to two white circles (Potassium dihydride, KH₂), and two separate white circles (Hydrogen atoms, 2H). i) Word equation: Chlorine + Potassium tetrahydride → Dihydrogen chloride + Potassium dihydride + Hydrogen atoms ii) Chemical equation: Cl + KH₄ → ClH₂ + KH₂ + 2H c) Step 1: Identify reactants and products from the model using the key. Reactants: One molecule of one black circle bonded to four white circles (Methane, CH₄) and two molecules of two red circles bonded together (Oxygen, 2O₂). Products: One molecule of one black circle bonded to two red circles (Carbon dioxide, CO₂) and two molecules of one red circle bonded to two white circles (Water, 2H₂O). i) Word equation: Methane + Oxygen → Carbon dioxide + Water ii) Chemical equation: CH₄ + 2O₂ → CO₂ + 2H₂O d) Step 1: Identify reactants and products from the model using the key. Reactants: Two molecules of two red circles bonded together (Oxygen, 2O₂) and two molecules of two green circles bonded together (Chlorine, 2Cl₂). Products: Four molecules of one green circle bonded to one red circle (Chlorine monoxide, 4ClO). i) Word equation: Oxygen + Chlorine → Chlorine monoxide ii) Chemical equation: 2O₂ + 2Cl₂ → 4ClO
