Giải thích các bước giải:
CÂU 1,
a,CH3COOH+NA→CH3COONA+H2
c, Ca(OH)2 + 2CH3COOH → (CH3COO)2Ca + 2H2O
b,2CH3COOH + Na2CO3 → 2CH3COONa + H2O + CO2
d,2CH3COOH + Mg → H2 + (CH3COO)2Mg
CÂU 4
1.
C + O2 → CO2
2.
CaO + CO2 → CaCO3
3.
CaCO3 → CaO + CO2
4
CaO + H2O → Ca(OH)2
5
Ca(OH)2 + 2CO2 → Ca(HCO3)2
b,
1.
C2H4 + H2O → C2H5OH
2
C2H5OH + O2 → CH3COOH + H2O
3,
2CH3COOH + Na2CO3 → 2CH3COONa + H2O + CO2
4.
CaO + CO2 → CaCO3
câu 9.a,
NaHCO3+ HCl -> NaCl+ CO2+ H2O
Ca(OH)2+ 2HCl -> CaCl2+ 2H2O
CaCO3+ 2HCl -> CaCl2+ CO2+ H2O
b,
Ca(OH)2+ Na2CO3 -> CaCO3+ 2NaOH
CaCl2+ Na2CO3 -> CaCO3+ 2NaCl
c,
NaHCO3+ NaOH -> Na2CO3+ H2O
câu 5
Mg + 2 CH3COOH → (CH3COO)2Mg + H2
2CH3COOH + MgO → H2O + (CH3COO)2Mg
Ca(OH)2 + 2CH3COOH → (CH3COO)2Ca + 2H2O
