What is released as vapor when hydrates are heated?
When any liquid is heated and a vapour is given off, it is usually a gaseous form of that liquid. Although it can usually result in water being given off if a hydroxide and another diatomic molecule is heated eg. OH and CO3 (these are only the diatomic molecules) into H20 and CO2.Hydrate is a term used in inorganic chemistry and organic chemistry to indicate that a substance contains water. hence water is the vapour that is given off
What do hydrocarbons give off when they are heated?
The products of hydrocarbons burning are carbon dioxide and water.
What happens when barium chloride is heated?
When heated gently, the red burgundy CoCl2.6H2O will decomposes into the violet CoCl2.2H2O then to the blue anhydrous CoCl2. Note: When this anhydrous compound is dissolved in water it will go back to the original red burgundy color.
Can you combine water with neon?
Some dinoflagellates give off light. A chemical reaction in the cells produces light similar light produced by a firefly. water filled with these dinoflagellates glows like a twinkling neon light.
What is the term for the process by which a portion of a glacier breaks off and falls into the water?
The answer is a term called, Glacial Calving
What would happen if the hydrate was not heated long enough to drive off all the water?
The compound remain a hydrate.

The answer is 10 moles water.
On heating the hydrate how many moles of water should be driven off per mole of hydrate of sodium sulfate?
10 moles of water are released.

wondering the same thing.
What are hydrates and what is hydration?
Some salts have a property called "hygroscopy". This means that they absorb water from the air in a preset ratio (like, 5 molecules of water for every 2 units of the salt for example). They give this water off when heated. Therefore, there are actually two forms of the salt, they "hydrate" or "hydrous" form, which has the water, and the "anhydrate" or "anhydrous form", which does not. These two forms can have surprisingly different properties. Hydration is the process of going from an anhydrate to a hydrate (the source of the water doesn't matter, so don't say it's "absorbing water from the air").
How would you dehydrate gelatin?
To hydrate gelatine one soaks it in boiling water
What will give off steam after heated?
Steam comes from boiling water.
How do you remove water from a hydrate?
the water can be removed heating the anhydrous.
What do hydrocarbons give off when they are heated?
The products of hydrocarbons burning are carbon dioxide and water.
When liquid water is heated are collisions between molecules more violent?
Yes, as water is heated, the molecules continue to speed up until they are moving so fast that they fly off which is what we call steam when you are boiling water.
