What is the oxidation number in Carbonate?

The oxidation number of carbon in carbonate (CO3^2-) is +4. Oxygen has an oxidation number of -2, so the three oxygen atoms contribute a total of -6. To balance the charge of -2 for the entire carbonate ion, the carbon atom must have an oxidation number of +4.

What is the change in oxidation number of aluminum in the reaction of aluminum with oxygen gas to make aluminum oxide?

From '0' to '3'. Elemental aluminium is in oxidation state zero (0). When it combines with oxygen to form aluminium oxide , it 'looses' its three outermost electrons to oxygen. Hence aluminium metal becomes the aluminium cation (Al^3+), which is oxidation state '3'.

What is the oxidation number of carbon in carbonate?

The oxidation number of carbon in carbonate (CO3^2-) is +4. In the carbonate ion, each oxygen atom has an oxidation number of -2, so the overall charge of the ion is -2. This means the oxidation number of carbon must be +4 to balance the charges in the compound.
