Question

Bantulah saya...
1. Ba(OH)2 + NH4Cl -->
2. K2O (s) + H2SO4 (aq) -->
3. Fe(s) + H2SO4 (pekat) -->
4. Sn(s) + H3PO4(aq) -->
5. Ag(s) + HCl + HNO3 -->

Answer 1

1) Ba(OH)2 + 2NH4Cl -> BaCl2 + 2NH4OH

2) K2O(s) + H2SO4(aq) -> K2SO4 + H2O

3) Fe(s) + H2SO4(l) -> FeSO4(l) + H2(g)

4) Sn(s) + H3PO4(aq) -> SnPO3(l) + 3/2H2(g)

5) Ag (s) + HCl -> AgCl + 1/2H2(g)
