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 substance is given off when the salt solution is heated gently?
Water vapor is given off when a salt solution is heated gently. As the solution heats up, the water molecules begin to evaporate, leaving behind the salt particles.
How could you show that water is given off when epsom salts are heated?
When epsom salts are heated, water vapor is produced as a byproduct. This can be shown by heating epsom salts in a test tube and collecting the water vapor produced in a cooled condenser, where it will condense back into liquid water. The presence of liquid water in the condenser confirms that water is given off during the heating of epsom salts.
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.

What happens when heating hydrate of calcium sulfate how many moles of water should be driven off per mole of hydrate?
When heating hydrate of calcium sulfate, typically two moles of water are driven off per mole of hydrate. This process is known as dehydration, where the water molecules are removed from the compound as it is heated, resulting in the formation of an anhydrous compound.
The hydrate of sodium sulfate on heating the hydrate how many moles of water should be driven off per mole of hydrate?
The answer is 10 moles water.
The hydrate sodium sulfate on heating the hydrate how many moles of water should be driven off per mole of hydrate?
For sodium sulfate decahydrate (Na2SO4·10H2O), on heating, 10 moles of water molecules will be driven off per mole of the hydrate. Each formula unit of the hydrate contains 10 water molecules.
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.
How do you remove water from a hydrate?
To remove water from a hydrate, you can heat it gently to drive off the water molecules, leaving behind the anhydrous compound. This process is called dehydration or desiccation. The temperature at which this occurs will depend on the specific hydrate compound.
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").
What gas is given off when Potassium Hydroxide and Sodium Hydroxide heated?
When Potassium Hydroxide is heated, it gives off water vapor (H2O). When Sodium Hydroxide is heated, it also gives off water vapor (H2O).
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.
What do hydrocarbons give off when they are heated?
The products of hydrocarbons burning are carbon dioxide and water.
