Question

Egalati formulele:

$H_{2}SO_{4}$ + CuO
$HNO_{3}$ + NaOH
HCl + $CaCO_{3}$
$H_{2}SO_{4}$ + $Cu(OH)_{2}$
$Ca(OH)_{2}$ + $CO_{2}$
NaOH + HCl
NaOH + $CuSO_{4}$

Answer 1

H2SO4+CuO=CuSO4+H2O
HNO3+NaOH=NaNO3=H2O
2HCl+CaCO3=CaCl2+H2CO3
H2SO4+Cu(OH)2=CuSO4+2H2O
Ca(OH)2+CO2=CaCO3+H2O
NaOH+HCl=NaCl+H2O
2NaOH+CuSO4=Na2SO4+Cu(OH)2

Answer 2

H2SO4+CuO=CuSO4+H2O

HNO3+NaOH=NaNO3+H2O

2HCl+CaCO3=CaCl2+CO2(gaz)+H2O

H2SO4+Cu(OH)2=CuSO4+2H2O

Ca(OH)2+CO2=CaCO3+H2O

NaOH+HCl=NaCl+H2O

2NaOH+CuSO4=Na2SO4+Cu(OH)2
