Question

Составьте уравнения химической реакции:
1) Fe + CuSO4=
2)H2SO4 + Ba(OH)2=
3)CaO+ HCl=
4)Fe(OH)3=

Answer 1

1) $Fe$ + $CuSO_{4}$ ⇒ $FeSO_{4}$ + $Cu$
2) $H_{2}SO_{4}$ + $Ba(OH)_{2}$ ⇒ $BaSO_{4}$ + $2H_{2}O$
3) $CaO$ + $2HCl$ ⇒ $CaCl_{2}$ + $H_{2}O$
4) $2Fe(OH)_{3}$ ⇒ $Fe_{2}O_{3}$ + $3H_{2}O$
