1. The Chemical Formula:
Calcium hydrogen sulfate has the chemical formula Ca(HSO₄)₂.
2. Breaking Down the Formula:
* Ca: This represents one calcium atom.
* (HSO₄): This represents the hydrogen sulfate ion, which is a group of atoms bonded together.
* 2: The subscript "2" outside the parentheses means there are two hydrogen sulfate ions in the molecule.
3. Oxygen in the Hydrogen Sulfate Ion:
* Each hydrogen sulfate ion (HSO₄) has four oxygen atoms.
4. Total Oxygen Atoms:
Since there are two hydrogen sulfate ions and each has four oxygen atoms, the total number of oxygen atoms in calcium hydrogen sulfate is:
2 hydrogen sulfate ions * 4 oxygen atoms/hydrogen sulfate ion = 8 oxygen atoms
Therefore, there are 8 oxygen atoms in one molecule of calcium hydrogen sulfate.
