Question

AL2O3+H2=ZnO+H2=CrO3+2=

Answer 1

1) Al2O3 + 3H2 = 2Al + 3H2O

2) ZnO+H2=Zn+H2O

3) CrO3+H2=Cr+H2O

Answer 2

It appears that there is a confusion in the chemical equation you provided. The chemical equation should be properly formatted with reactants and products on each side of the arrow. Additionally, there should be coefficients in front of the chemical formulas to balance the equation correctly.

If you intended to write three separate equations, they would look like this:

1. Aluminum oxide (Al2O3) + Hydrogen gas (H2) → ??? (Incomplete equation)

2. ??? (Incomplete equation) + Hydrogen gas (H2) → Zinc oxide (ZnO)

3. ??? (Incomplete equation) + ??? (Incomplete equation) → Chromium trioxide (CrO3) + ??? (Incomplete equation)

Please provide the missing information, and I'll be happy to help you balance the equations or clarify any other questions you may have.
