A hydrate is a substance where in it contains water and other constituent elements. To know whether if that compound was a hydrate,you should record its mass, then put it in a test tube and heat it with a Bunsen burner. If the compound is a hydrate, the water in the compound will discharge in the form of water vapor. At the next 5-10 minutes, remove it in the test tube and weigh it up again. If the mass is now fewer, that means that there was water existing that has now evaporated, and the compound was a hydrate.
C. KOH + HBr → KBr + H₂O
Explanation:
The two equations above illustrates the conservation of matter. The law of conservation of matters states that
"in a chemical reaction, matter is neither created nor destroyed but transformed from one form to another".
By this law, we understand that the amount of a particular matter we are starting with should be the one we end with.
KOH + HBr → KBr + H₂O
Conserving Product Reactants
K 1 1
O 1 1
H 2 2
We can see that the amount on both sides are the same.

Answer:
The hypothetical van't Hoff factor of magnesium nitrate,
is <u>3 .</u>
Explanation:
Lets calculate -
We know that ,
Dissociation should be 100% for the hypothetical vant hoff factor , that is
and 
for
Therefore , putting the given values ,
<u>Hence , the answer is 3.</u>
