How to Write Chemical Formulas

Writing chemical formulas involves representing the elements and compounds involved in a chemical reaction or compound. Here's a step-by-step guide on how to write chemical formulas:

1. Identify the elements: Start by identifying the elements present in the compound or reaction. In the example you provided, the elements are copper (Cu), sulfur (S), oxygen (O), and nitrogen (N).

2. Determine the charges: Next, determine the charges of the ions or atoms involved. In the example, copper has a charge of +2 (Cu^2+), sulfur has a charge of +6 (S^6+), oxygen has a charge of -2 (O^2-), and nitrogen has a charge of -3 (N^3-).

3. Balance the charges: To balance the charges, you need to ensure that the total positive charge equals the total negative charge. In the example, the copper ion (Cu^2+) has a charge of +2, while the sulfate ion (SO4^2-) has a charge of -2. To balance the charges, you need two copper ions for every sulfate ion. Therefore, the formula for copper sulfate is CuSO4.

4. Add subscripts: If there are multiple atoms of an element in the compound, you need to indicate this using subscripts. In the example, there is only one atom of each element, so no subscripts are needed.

5. Combine multiple compounds: If you have multiple compounds in the formula, separate them using a plus sign (+). In the example, the formula you provided, CuSO4 + NO3, represents the combination of copper sulfate (CuSO4) and nitrate (NO3).

Therefore, the correct way to write the formula you provided is CuSO4 + NO3.

Please note that the example you provided, CuSO4 + NO3, is not a balanced chemical equation or a compound. It represents the combination of two separate compounds.
