Question

Na2O+2HO=____
Na OH+Cu CL2=___
CaO+H2 O=____
K+H2O=____
Ca (OH)2+CO2=_____​

Answer 1

Răspuns:

Explicație:

Na2 O + H2O=2NaOH

2NaOH + CuCl2= 2NaCl + Cu(OH)2

CaO + H2O= Ca(OH)2

2K +2 H2O=2KOH +H2

Ca(OH)2 +CO2= CaCO3 +H2O

Baze solubile : NaOH , KOH

Baze insolubile : Cu(OH)2 , Ca(OH)2
