What is the term a hydrate with the water heated off?
Anhydrous is the term for a hydrate with water heated off. when a hydrated salt is heated, it loses water of crystallization leaving an anhydrous salt.
When what is heated it looses water and becomes anhydrous?
hydrate
The solid residue that remains when a hydrate is heated is?
The anhydrous molecule or species. e.g. CuSO4.5H2O (hydrate) + heat ----> CuSO4 (anhydrous) + water vapor
What do you call a hydrate that is heated strongly?
Usually, if you heat a hydrate, in becomes an anhydrate, because the water of crystallization vaporizes. This results in a collapse of its crystal structure.
Why the process of heating hydrate compound should be heated slowly first?
Otherwise the compound will scorch!
What happens when a hydrate heated?
When a hydrate is heated, the water, h20 is evaporated, leaving only the anhydrous salt. If you add water to a anhydrous salt, it will transition back into a hydrate.

When anhydrous is heated it loses water and becomes what?
hydrate
When what is heated it looses water and becomes anhydrous?
hydrate
What would happen if the hydrate was not heated long enough to drive off all the water?
The compound remain a hydrate.

What is superheating?
Super heated to remove excessive moisture
How does the law of constant consumption apply to hydrate salts?
Whenever talking about a molecule of water, there is ALWAYS two atoms of Hydrogen and one atom of Oxygen. In a hydrate, water is part of the crystals. When a hydrate is heated, the composition of it is changed, because water is released. And as soon as the composition is changed, it is a new substance with new properties.
What is the difference between anhydrous and fused calcium chloride?
In theory no difference- both are CaCl2. However in practise fused is sold with a higher moisture content (usually). Fused CaCl2 is just the hydrate heated up to expel water - this gives the "anhydrous" form. in practise as this so deliquiscent- it takes up moisture readily. So if you analyse it you invariably find water!
Why do kernels explode?
If you are discussing popcorn kernels here (I wasnt sure) it is because they have moisture inside of them and when they are heated,moisture expands and they Pop.
