2) BaCl2 + Na2SO4 =

3) Al + Fe2O3 =

4) 2C4H6 + 11O2 =

5) Ag + Pb3(PO4)2 =

6) HBr =

7) K2CO3 + Cal2

Answer 1

Solution:

1) NO₂(g) + H₂O(l) → 2HNO₃(aq) + NO(g)

NO₂(g) + H₂O(l) → 2H⁺ + 2NO₃^-(aq) + NO(g)

2) BaCl₂(aq) + Na₂SO₄(aq) → BaSO₄(s) + 2NaCl(aq)

Ba²⁺(aq) + 2Cl^-(aq) + 2Na⁺(aq) + SO₄^2-(aq) → BaSO₄(s) + 2Na⁺(aq) + 2C^l-(aq)

Ba²⁺(aq) + SO₄^2-(aq) → BaSO₄(s)

3) Al(s) + Fe₂O₃(s) → 2Fe(s) + Al₂O₃(s)

4) 2C₄H₆(g) + 11O₂(g) → 8CO₂(g) + 6H₂O(l)

5) Ag(s) + Pb₃(PO₄)₂(s) → no reaction occurs

6) HBr(aq) → H⁺(aq) + Br^-(aq) (dissociation equation)

7) K₂CO₃(aq) + Cal₂(aq) → CaCO₃(s) + 2KI(aq)

2K⁺(aq) + CO₃^2-(aq) + Ca²⁺(aq) + 2I^-(aq) → CaCO₃(s) + 2K⁺(aq) + 2I^-(aq)

CO₃^2-(aq) + Ca²⁺(aq) → CaCO₃(s)
