Answer 1

1. 2Al(s) + 3Cl2(g) → 2AlCl3(s)2. Zn(s) + 2AgNO3(aq) → 2Ag(s) + Zn(NO3)2(aq)3. Cu(NO3)2(aq) + 2NaOH(aq) → Cu(OH)2(s) + 2NaNO3(aq)4. H2SO4(aq) + 2KOH(aq) → 2H2O(l) + K2SO4(aq)5. 2C2H6(g) + 7O2(g) → 4CO2(g) + 6H2O(g)6. Equation 1: Synthesis reaction7. Equation 2: Single replacement reaction8. Equation 3: Double replacement reaction9. Equation 4: Neutralization reaction10. Equation 5: Combustion reactionNet ionic equations:3. Cu2+(aq) + 2OH-(aq) → Cu(OH)2(s)4. H+(aq) + OH-(aq) → H2O(l)
