how would you sent up aluminum carbonate --> aluminum oxide + carbon dioxide.

im guessing AlCo3 --> AlO3+Co2 but i don't think that's right

Al is +3. Carbonate is -2. Formula is Al2(CO3)3

Aluminum oxide is Al2O3.
carbon dioxide is CO2.

To balance the chemical equation for the decomposition of aluminum carbonate (AlCO3) into aluminum oxide (Al2O3) and carbon dioxide (CO2), you need to follow these steps:

Step 1: Write down the unbalanced equation.

AlCO3 → Al2O3 + CO2

Step 2: Count the number of atoms for each element on both sides of the equation.

Left Side: 1 Al, 1 C, 3 O
Right Side: 2 Al, 3 C, 5 O

Step 3: Balance the carbon (C) atoms.

To balance the carbon atoms, you need an equal number of carbon atoms on both sides of the equation. In the given equation, there is one carbon atom on the left side and three on the right side. To balance it, you can place a coefficient of 3 in front of CO2:

AlCO3 → Al2O3 + 3CO2

Step 4: Balance the oxygen (O) atoms.

Next, you should balance the oxygen atoms. On the left side, there are three oxygen atoms from the AlCO3, and on the right side, there are five oxygen atoms from the Al2O3 and the three CO2 molecules. To balance them, you can place a coefficient of 3 in front of Al2O3:

AlCO3 → 3Al2O3 + 3CO2

Step 5: Balance the aluminum (Al) atoms.

Now, the equation is almost balanced, but the number of aluminum atoms is not equal on both sides. On the left side, there is one aluminum atom, and on the right side, there are six aluminum atoms. To balance it, you can place a coefficient of 2 in front of AlCO3:

2AlCO3 → 3Al2O3 + 3CO2

Now, the equation is balanced with two AlCO3 units decomposing to produce three Al2O3 units and three CO2 molecules.
