Question

закончить возможные уравнения реакций H2SO4+CuO=Fe+O2=BaO+H2O=Al(OH)3+HNO3=

Answer 1

2Fe + O2 = 2FeO 
H2SO4+CuO=CuSO4+Н2О 
ВаО+Н2О=Ва (ОН)2
Al(OH)3 + 3HNO3 = Al(NO3)3 + 3H2O 
Пожалуйста.

Answer 2

1) H2SO4 + CuO = CuSO4 + H2O H2SO4 reacts with CuO to form CuSO4 (copper sulfate) and H2O (water).

2) Fe + O2 = Fe2O3 Iron (Fe) reacts with oxygen (O2) to form iron (III) oxide (Fe2O3).

3) BaO + H2O = Ba(OH)2 Barium oxide (BaO) reacts with water (H2O) to form barium hydroxide (Ba(OH)2).

4) Al(OH)3 + HNO3 = Al(NO3)3 + H2O Aluminum hydroxide (Al(OH)3) reacts with nitric acid (HNO3) to form aluminum nitrate (Al(NO3)3) and water (H2O).
