Formula Compound Name 11 NO2 The Correct Answer and Explanation is : Here are the chemical compounds corresponding to the provided formulas: Explanation: The names of chemical compounds are derived from their molecular formulas, which indicate the types and numbers of atoms present. The naming conventions vary based on the elements involved and their oxidation

The Correct Answer and Explanation is : 1. Molar mass of Copper Sulfate (CuSO₄·5H₂O): To find the molar mass of copper sulfate (CuSO₄·5H₂O), we add up the atomic masses of each component in the formula: Now, adding them all together: [63.55 \, \text{g/mol} \, (\text{Cu}) + 32.07 \, \text{g/mol} \, (\text{S}) + 64.00 \, \text{g/mol}
