Разложите на ионы.1)Сu(OH)2+H2SO4= 2)Na2SiO3+HNO3= 3)Fe(OH)3+Hcl= 4)NaOH+Zn(NO3)2. Решите пожалуйста надо очень срочно!
Сu(OH)2+H2SO4=CuSO4 + 2H2O
Cu+2OH+H+SO4=Cu+SO4+2H+2O
Cu+ SO4 =CuSO4
Na2SiO3+2HNO3= 2NaNO3 + H2SiO3
2Na + SiO3+ 2H+ 2NO3= 2Na + 2NO3 + H2SiO3
SiO3 + 2H = H2SiO3
Fe(OH)3 + 3HCl → FeCl3 + 3H2O
Fe(OH)3+3H+3Cl=Fe+3Cl+3H2O
Fe(OH)3+3H=Fe+3H2O
Zn(NO3)2+2NaOH=Zn(OH)2+2NaNO3
Zn+ NO3 + 2Na + 2OH =Zn(OH)2 + 2Na+ 2NO3Zn+ 2OH=Zn(OH)2
