Fill in the blank with the correct number to balance the equation: 4cr + 3o2 → cr2o3. (enter only a whole number. ).

4Cr + 3O2 > 2Cr2O3

Explanation:

We need to balance both the sides of the equation, that is, number of moles of reactants should be equal to the number of moles of products. So,

4Cr + 3O2 > 2Cr2O3

Comparing the moles of elements, we see that the equation is now completely balanced.

Hope it helps :)
