Part 1: Fill in the blanks below to state Newton’s three laws of motion: Newton’s First Law: All objects will remain at , or will continue to move at a constant in the same unless acted upon by an unbalanced . This property is called .

Newton’s Second Law: Unbalanced forces cause an object to .

Newton’s Third Law: Every action produces an equal and opposite . When one object exerts a force on another object, the second object pushes back with the same amount of .

all objects will remain at rest, or will continue to move at a constant speed in the same velocity unless acted upon by an unbalanced force. This property is called interia

Explanation:

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%
