Explanation:

The chemical formula of the copper (II) sulfate pentahydrate is

In the given chemical formula:

Number of copper atoms = 1

Number of sulfur atoms = 1

Number of oxygen atoms = 9

Number of hydrogen atoms = 10

Hence, in copper (II) sulfate pentahydrate, only 1 sulfur atom is present.

they vary. it used to be meat, grain, bread, candy, beverages, donuts, and fruits/vegetables. now they added exercise in.

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.
