Your unbalanced equation is _Al + _Cr2O3 ----> _Cr + _Al2O3. Multiply aluminum (Al) and chromium (Cr) ratio by 2, so each side has the same amount of each element. As a result, the equation 2Al + Cr2O3 -----> 2Cr + Al2O3 is balanced. This is a single replacement reaction.
4 Cr + 3 O2 = 2 Cr2O3
Fe2+CO2

2C3H4O7 + O2 -> 6CO2 + 4H2O
C(s) + O2(g) -> CO2(g)
The balanced equation is: CH4 + 2 O2 → CO2 + 2 H2O
CO2 is not an equation, so it cannot be balanced. It is a chemical formula.

The balanced equation is: CH4 + 2 O2 → CO2 + 2 H2O
Yes. Except that the word is equals, not eqauls.
The combustion of methane can be balanced in the following manner. One molecule of CH4 plus two molecules of O2 produces one molecule of CO2 plus one molecule of H2O.
6CO2 + 6H20 +energy yields C6H12O6 + 6O2. This is the equation for photosynthesis.
CO2 is not an equation, so it cannot be balanced. It is a chemical formula.
No, the balanced equation is 6Ca + 3O2 ---> 6CaO. The product, calcium oxide, is CaO and not CaO2.
co2 + c = 2co I'm guessing you meant to say 'equals' after the c, because if there wasn't a yield/equal sign, you can't balance it.
CO2 + C → 2CO Carbon dioxide combines with carbon to form carbon monoxide (in the laboratory) by passing CO2 over heated charcoal. In the environment, it is formed by incomplete oxidation of hydrocarbons.
