Answer:
MgSO4.7H2O
Explanation:
The heating removes all the water (H2O) in the crystal.
The mass of the water removed = 82-40.1 = 41.9 grams.
The formula of the hydrated salt = MgSO4. xH2O
The ratio in of the masses of MgSO4 : H2O = 40.1 : 41.9
Dividing these by the molar masses we get
40.1/ 120.4 to 41.9 / 18.016
= 0.33 : 2.33
= 1 : 7.
So there are 7 water molecules n the hydrate.
Answer:
size-humans brains are usually larger than animals, shape-some animal brains are shaped very odd, and the cerebrum-that is the part of the brain that makes us human.
It doesn't have enough solute. So say someone likes sweet tea. If you were to add more sugar it would still dissolve no matter how much is in the glass. Sorry if this is confusing.
Answer:
The weight of the plane is (mass) x (acceleration of gravity).
Neither of these changes when the plane rises from the ground.
Its weight on the ground is equal to (the same as) its weight in the air.
