Question

помогите с химией!!!! Zn+HCl = NaOHф+HCl= K2CO3+HCl= K2SO4+HCl= NaOH+H2SO4= NaOH+FeCl3= CuSO4+NaOH= CuSO4+BaCl2=

Answer 1

Zn+2HCl = ZnCl2 +H2

NaOHф+HCl=NaCl +H2O

 K2CO3+2HCl=KCl2 + CO2 + H2O 

K2SO4+2HCl=KCl2 + H2SO4 

2NaOH+H2SO4=Na2SO4 + 2H2O

3NaOH+FeCl3=3NaCl + Fe(OH)3 

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

CuSO4+BaCl2=BaSO4+CuCl2

Answer 2

Zn + 2HCl= ZnCl2 + H2

 K2CO3 + 2HCl = 2KCl + H2CO3

K2SO4 + 2HCl = 2KCl + H2SO4

2NaOH+H2SO4= Na2SO4 + 2H2O

 3NaOH+FeCl3= 3NaCl + Fe(OH)3

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

CuSO4+BaCl2= CuCl2 + BaSO4
