balance:
Al2(CO3)3 --> Al2O3 + CO2

i don't know how to do the reactant side so i can figure out the product side...

• chemistry -

first, note that there are 2 Al on each side. So, we need to balance the

CO3 and the O3CO2

as written, we have
3C and 9O on the left, and
1C and 5O on the right.
But, 3O are bound to the balanced Al, leaving
1C and 3O to play with. Looks like we just need to triple the CO2:

Al2(CO3)3 --> Al2O3 + 3CO2

Left: 3C,9O
Right: 3C,9O
