Question

1. a student analyzes the formula h₂so₄. which two statements are supported by the periodic table? the formula includes three different elements: hydrogen (h), sulfur (s), and oxygen (o) the subscript 2 means there are two hydrogen atoms. sulfur has a subscript of 4, so there are four sulfur atoms. the number of chemical symbols shows the number of molecules. oxygen is not part of this compound.

Explanation:

In the chemical formula $H_2SO_4$, the 'H' represents hydrogen, 'S' represents sulfur and 'O' represents oxygen, so there are three elements. The sub - script 2 next to 'H' indicates 2 hydrogen atoms. Sulfur has no sub - script (implied 1), and the number of chemical symbols does not represent the number of molecules. Oxygen is clearly part of the compound.

Answer:

The formula includes three different elements: hydrogen (H), sulfur (S), and oxygen (O)
The subscript 2 means there are two hydrogen atoms.
