Is the following picture an example of a chemical change or a physical change? SOMEONE PLEASE HELP ILL GIVE

A physical change, because the atoms are rearranging to form new molecules.

A physical change, because the molecules are staying the same.

A chemical change, because the atoms are rearranging to form new molecules.

A chemical change, because the molecules are staying the same.

A physical change because the molec are staying the same

Explanation:

when water is evaporated it still is water just not in liquid form

1. for the first question, we must find the mass of the anhydrous salt, mgso₄. the molar mass for mgso₄·7h₂o is 246.47 g/mol, while that of mgso₄ is 120.37 g/mol.7.834 g mgso₄·7h₂o * 1 mol mgso₄·7h₂o/246.47 g * 1 mol mgso₄/1 mol mgso₄·7h₂o * 20.37 g mgso₄/mol = 0.647 g mgso₄

2. mass of water = mass of sample - mass of anhydrous salemass of water = 7.834 - 0.647 = 7.19 gpercent water in hydrate = 7.19/7.834 * 100 = 91.74%

c, liquids evaporate, creating a gas
