Copper(II) carbonate is a compound with the chemical formula CuCO3. When heated, it decomposes into two products: cupric oxide (CuO) and carbon dioxide (CO2).

## Word Equation:

* copper(II) carbonate → cupric oxide + carbon dioxide*

## Input Interpretation:

* CuCO3 → CuO + CO2*

To balance the equation, we follow the steps below:

**Step 1: **Write the unbalanced equation.

* CuCO3 → CuO + CO2*

**Step 2: **Assign variables to each element and balance the atoms on both sides of the equation.

* c1CuCO3 → c2CuO + c3CO2*

*C: **c1 = c3*

*Cu: **c1 = c2*

*O: **3c1 = c2 + 2c3*

**Step 3: **Choose an arbitrary value for one of the coefficients, and solve for the others.

Let's set c1 = 1.

*c1 = 1*

*c2 = 1*

*c3 = 1*

**Step 4: **Substitute the coefficients back into the equation to obtain the balanced equation.

* CuCO3 → CuO + CO2*

## Balanced Chemical Equation

The balanced chemical equation is:

* CuCO3 → CuO + CO2*

This means that one molecule of copper(II) carbonate decomposes into one molecule of cupric oxide and one molecule of carbon dioxide. The balanced equation is important because it ensures that the same number and type of atoms are present on both sides of the equation, which is necessary for chemical reactions to occur.
