Transcribed Image Text:**Activity 4: Balance Equations**
1. Write balanced reaction equations, including symbols describing the physical state of the chemicals, for the following reactions:
1.1. Ca + H₂O → Ca(OH)₂ + H₂
1.2. MnO₂ + HCl → MnCl₂ + Cl₂ + H₂O
1.3. NO₂ + H₂O → HNO₃ + NO
1.4. Fe + H₂O → Fe₃O₄ + H₂
1.5. CO₂ + C → CO
1.6. Mg + CO₂ → MgO + C
1.7. NaOH + H₂SO₄ → Na₂SO₄ + H₂O
1.8. H₂S + SO₂ → S + H₂O
1.9. NaHCO₃ + H₂SO₄ → Na₂SO₄ + 2H₂O + 2CO₂
2. Balance the following equations, using chemical symbols in place of words:
2.1. Copper(II) oxide + hydrogen → copper metal + water
2.2. Sodium metal + water → sodium hydroxide + hydrogen
2.3. Iron + chlorine → iron(III) chloride
2.4. Carbon + bromine → carbon tetrabromide
**Experiment 5: Compare the amount of product with the amount of reactant**
(Note: This section likely involves setting up and performing experiments to understand stoichiometry ratios and relationships between products and reactants in chemical reactions.)
