Question

Уравнения хим. реакций , расставить коэф.Na2O+H20--->Na2O+HNO3--->Na2O+SO3--->---------------------------------------------------------------------------------------------NaOH+CO2--->NaOH+CuSO4--->NaOH+ZnO--->

Answer 1

Na2O+H2O=2NaOH

Na2O+2HNO3=2NaNO3+H2O

Na2O+SO3=Na2SO4

2NaOH+CO2=Na2CO3+H2O

2NaOH+CuSO4=Na2SO4+Cu(OH)2↓

2NaOH+ZnO=Na2ZnO2+H2O

Answer 2

Na2O+H20--->2Na(OH)

Na2O+2HNO3--->2NaNO3 + H20

Na2O+SO3---> Na2SO3

2NaOH+CO2--->Na2CO3 + H20

2NaOH+CuSO4--->Na2SO4 + Cu(OH)2

NaOH+ZnO---> Na2ZnO2 + H2O
