Classify the following chemical reactions and Identify if the chemical equation is balance or not
Answer (1)
A. Classify the chemical reactions: 1. Zn(s) + N₂(g) → Zn₃N₂(s) ● Combination Reaction: Two or more reactants combine to form a single product. 2. BaCO₃(s) → BaO(s) + CO₂(g) ● Decomposition Reaction: A single reactant breaks down into two or more products. 3. Cl₂(g) + 2NaI(aq) → 2NaCl + I₂ ● Single Replacement Reaction: One element replaces another in a compound. 4. Ba(OH)₂ + Na₂SO₄ → BaSO₄ + 2NaOH ● Double Replacement Reaction: Two reactants exchange ions. 5. KClO₃(s) → KCl(s) + O₂(g) ● Decomposition Reaction: A single reactant breaks down into two or more products.B. Balance the chemical equations: 1. Mg(s) + Cl₂(g) → MgCl₂(s) ● Balanced: The equation is already balanced. 2. N₂ + 3H₂ → 2NH₃ ● Not Balanced: ● We need 2 nitrogen atoms on the right side (multiply NH₃ by 2). ● We need 6 hydrogen atoms on the left side (multiply H₂ by 3). 3. Cl₂ + 2KI → 2KCl + I₂ ● Balanced: The equation is already balanced. 4. 2NaOH + H₂SO₄ → Na₂SO₄ + 2H₂O ● Not Balanced: ● We need 2 sodium atoms on the left side (multiply NaOH by 2). ● We need 2 hydrogen atoms on the right side (multiply H₂O by 2). 5. 2NaClO₃ → 2NaCl + 3O₂ ● Balanced: The equation is already balanced.
