Balancing Chemical Equations

Let's balance the chemical equations provided:

1. Fe2O3 + H2 = H2O + Fe To balance this equation, we start by counting the atoms of each element on both sides of the equation. Then, we adjust the coefficients to make the number of atoms of each element equal on both sides.

The balanced equation is: ``` Fe2O3 + 3H2 = 3H2O + 2Fe ```

2. RbO + Al = Al2O3 + Rb The balanced equation is: ``` 2RbO + 4Al = 2Al2O3 + 4Rb ```

3. CrO3 + Mg = MgO + Cr The balanced equation is: ``` CrO3 + 3Mg = 3MgO + Cr ```

4. Al + H2O = Al(OH)3 + H2 The balanced equation is: ``` 2Al + 6H2O = 2Al(OH)3 + 3H2 ```

5. AgCl = Ag + Cl2 The balanced equation is: ``` 2AgCl = 2Ag + Cl2 ```

6. Zn + Br2 = ZnBr2 The balanced equation is: ``` Zn + Br2 = ZnBr2 ```

7. Al + Cl2 = AlCl3 The balanced equation is: ``` 2Al + 3Cl2 = 2AlCl3 ```

8. Al + O2 = Al2O3 The balanced equation is: ``` 4Al + 3O2 = 2Al2O3 ```

9. Fe + Cl2 = Fe3O4 The balanced equation is: ``` 3Fe + 4Cl2 = Fe3O4 ```

10. HgO = Hg + O2 The balanced equation is: ``` 2HgO = 2Hg + O2 ```

11. Ag2O = Ag + O2 The balanced equation is: ``` 2Ag2O = 4Ag + O2 ```

12. Au2O3 = Au + O2 The balanced equation is: ``` 2Au2O3 = 4Au + 3O2 ```

These balanced chemical equations represent the conservation of mass and atoms in chemical reactions.
