Question

Решите пожалуйста 1 и 3
Буду благодарна очень!!

Answer 1

1)CaCl2 + K2CO3 = CaCO3 + 2KCl
AlBr3 + 3NaOH = Al(OH)3 + 3NaBr
KNO3 + NaCl = KCl + NaNO3
KOH + HNO3 = KNO3 + H2O

3) FeS + 2HCl = FeCl2 + H2S
CaCO3 + 2HCl = CaCl2 + CO2 + H2O

Answer 2

1) CaCl₂ + K₂CO₃ = 2KCl + CaCO₃
AlBr₃ + 3NaOH = Al(OH)₃ + 3NaBr
KNO₃ + NaCl = KCl + NaNO₃
KOH + HNO₃ = KNO₃ + H₂O
3) CaCO₃ + 2HCl = CaCl₂ + CO₂ + H₂O
FeS + 2HCl = FeCl₂ + H₂S
