Question

Balance these equations:Sc2O3(s) + SO3(l) ⟶ Sc2(SO4)3(s)Ca3(PO4)2(aq) + H3PO4(aq) ⟶ Ca(H2PO4)2(aq)Al(s) + H2SO4(aq) ⟶ Al2(SO4)3(s) + H2TiCl4(s )+ H2O(g) ⟶ TiO2(s) + HCl(g)

Answer 1

1. Sc2O3(S) + 3SO3 → Sc2(SO4)3(S)

2. Ca3(PO4)2 + 4H3PO4 → 3Ca(H2PO4)2

3. 2Al + 3H2SO4 → Al2(SO4)3 + 3H2

4. TiCl4 + 2H2O → TiO2 + 4HCl

Step-by-step explanation:

1. Sc2O3(S) + 3SO3 → Sc2(SO4)3(S)

2. Ca3(PO4)2 + 4H3PO4 → 3Ca(H2PO4)2

3. 2Al + 3H2SO4 → Al2(SO4)3 + 3H2

4. TiCl4 + 2H2O → TiO2 + 4HCl
