Wyjaśnienie:
Zad.1
1. CsOH + HNO₃ = CsNO₃ + H₂O
2. Cs₂O + 2HNO₃ = 2CsNO₃ + H₂O
3. 2Cs + 2HNO₃ = 2CsNO₃ + H₂↑
4. 2CsOH + N₂O₅ = 2CsNO₃ + H₂O
5. Cs₂O + N₂O₅ = 2CsNO₃
Zad.2 chlorek berylu
1. Be(OH)₂ + 2HCl = BeCl₂ + 2H₂O
2. BeO + 2HCl = BeCl₂ + H₂O
3. Be + 2HCl = BeCl₂ + H₂↑
4. Be + Cl₂ = BeCl₂
Zad.3
1. 2RbOH + H₂S = Rb₂S + 2H₂O
2. Rb₂O + H₂S = Rb₂S + H₂O
3. 2Rb + H₂S = Rb₂S + H₂↑
4. 2Rb + S = Rb₂S
