1. Na2S +HCl -> NaCl+H2S
2. Na2SO3+HCl -> NaCl+H2O+SO2
3. CaO+P2O5 -> Ca3(PO4)2
Mohon bantuannya 🙂
Bentuk persamaan reaksi kimia:
1. 2Na₂S + 2HCl -> 2NaCl + H₂S₂
2. Na₂SO₃ + 2HCl -> 2NaCl + H₂O + SO₂
1. Na2S + 2 HCl —> 2 NaCl + H2S
2. Na2SO3 + 2 HCl —> 2 NaCl + H2O + SO2
3. 3 CaO + P2O5 —> Ca3(PO4)2
