Question #3 (pg. 121)

3.) a.) 2 Hydrogen Chlorides plus one Magnesium make a product of two hydrogens plus Magnesium Chloride because Magnesium is reactive to Hydrogen chloride therefore making a new substance. 

    b.) In the reactants Hydrogen Chloride is a compound and Magnesium is an element and in the reactants Hydrogen is an element and Magnesium Chloride is a compound.

    c.)

1.) 

a.) 

b.)

3.) The Law of conservation of matter like many scientific laws, summarizes what has been learned by careful observation of nature. It is basically the concluding part to all of our labs.
