初三化学方程式

Fe+H2SO4=
CuO+H2SO4=
Fe2O3+HCl=
Cu（OH)3+HCl=
Fe(OH)3+HCl=
BaCl2+H2SO4=
是等号哦 科学达人应该懂得

Answer 1

Fe+H2SO4=FeSo4+H2!
CuO+H2SO4=CuSO4+H2O
Fe2O3+6HCl=2FeCl3+3H2O
Cu（OH)2+2HCl=CuCl2+2H2O
Fe(OH)3+3HCl=FeCl3+3H2O
BaCl2+H2SO4=BaSO4:+2HCl

!是气标符号 ：是沉淀符号

Answer 2

Fe+H2SO4==FeSO4+H2↑
CuO+H2SO4=cuso4+h20
Fe2O3+HCl=FeCl2+H2O
4是 Cu（OH)2+HCl=CUSO4+2H2O 铜是+2价 和-1价 但写在前面的是正价所以是+2
BaCl2+H2SO4= BaSO4（沉淀）+ 2HCI

Answer 3

FeSo4+H2↑
CuSo4+H2o
2FeCl2+2H2O
2CuCl3+3H2O
BaSo4↓+2HCl

Answer 4

Fe+H2SO4==FeSO4+H2↑

CuO+H2SO4=cuso4+H2O

Fe2O3+6HCl=2FeCl3+3H2O

Cu（OH)2+2HCl=CuCl2+2H2O

Fe(OH)3+3HCl=FeCl3+3H2O

Bacl2+H2So4===BaSo4(沉淀)+2HCl

Answer 5

Fe+H2SO4=FeSO4+H2↑
CuO+H2SO4=CuSO4+H20
Fe2O3+HCl=2FeCl3+3H2O
Cu（OH)2+2HCl=CuCl2+2H2O
Fe(OH)3+3HCl=FeCl3+3H2O
BaCl2+H2SO4=BaSO4↓+2HCl

Answer 6

Fe + H2SO4 = FeSO4 + H2↑
CuO + H2SO4 = CuSO4 + H2O
Fe2O3 + 6HCl = 2FeCl3 +3 H2O
Cu（OH)2 + 2HCl= CuCl2 +2 H2O
Fe(OH)3+3HCl= FeCI3 +3 H2O
BaCl2+H2SO4= BaSO4↓+ 2HCI
