- 实验室制取下列物质的反映方程式是什么NH3H2HClNaOHO2
- NH3 H2 Hl NaOH O2 CH4 H2S K2S
N2
- 2NH4Cl+Ca(OH)2=加热=CaCl2+2H2O↑+2NH3↑
Zn+H2SO4==ZnSO4+H2↑
NaCl+H2SO4(浓)=加热=NaHSO4+HCl↑
Ca(OH)2+Na2CO3==CaCO3↓+2NaOH
2KClO3=加热[MnO2催化]=2KCl+3O2↑
CH3COONa+NaOH=加热=Na2CO3+CH4↑
Na2S+H2SO4==Na2SO4+H2S↑
2KOH+H2S==K2S+2H2O
2NH3+3CuO=加热=N2↑+3Cu+3H2O↑
