How to write this kind of chemical reaction equation? Barium hydroxide of equal volume and concentration is mixed with ammonium bicarbonate solution It's the amount of such substances
Ba(OH)2+NH4HCO3==BaCO3↓+NH3↑+2H2O
nBa(OH)2:nNH4HCO3=1:1
Write the following chemical reaction equation,
Impurities: (impurities in brackets)
CO(CO2) ,NaCl(HCl) ,Na2SO4(NaOH) ,NaOH(Na2CO3) ,FeSO4(CuSO4) ,N2(O2) ,CaO(CaCO3) ,Na2CO3(NaOH)
CO2 + 2naoh = = = = Na2CO3 + H2O (co does not react with NaOH) Na2CO3 + 2HCl = 2nacl + H2O + CO2 ↑ (excess HCl can be removed by heating) 2naoh + CuSO4 = Na2SO4 + Cu (OH) 2 ↓ (precipitation can be removed by filtration) Na2CO3 + Ca (OH) 2 = 2naoh + CaCO3 ↓
