Methane hydrate, also called methane clathrate, or methane ice, is a compound containing large amounts of the natural gas methane in a water crystal form, rather like ice. It is found on the sea bed, under layers of sediment.
The problems with harvesting it are many.
- Drilling rigs have to be able to reach around 500 metres (1600 feet) to the ocean floor, then usually more than double that depth to reach the clathrate. This is difficult.
- It is mostly found offshore, where the continental shelf starts to slope deeply down. Installing and controlling pipelines here is extremely difficult.
- Sloping seabeds are often unstable, and removing the stabilizing clathrate can lead to landslides. There is evidence of a huge landslide off Norway 8000 years ago which caused a 25 metre tsunami in Norway and Scotland. Scientists believe an unstable clathrate deposit nearby decomposed from temperature and pressure changes at the end of the last ice age.
- The clathrate is under high pressure and low temperature. When it is released it becomes unstable and will leak. Containing it as it rises will be extremely difficult.
- The biggest problem is that methane is a powerful greenhouse gas that, together with carbon dioxide, is the cause of global warming. Scientists fear that the release and escape of methane from methane clathrate harvesting could trigger a massive warming boost to the earth's atmosphere.

What is hydrate sub cooling?
Hydrate subcooling refers to the temperature difference between the equilibrium temperature at which hydrate formation occurs and the actual temperature of the fluid or gas mixture. It is an important factor in the management of hydrate formation in pipelines and production systems, as subcooling can prevent the unwanted formation of hydrates by keeping the mixture below the hydrate formation temperature. Proper subcooling can enhance system efficiency and reduce operational risks associated with hydrate blockages.
What is the formula for cupric sulfate hydrate?
The formula for cupric sulfate hydrate is CuSO4 · xH2O, where x represents the number of water molecules associated with each copper sulfate molecule.
How a hydrate is represented?
A hydrate is represented by writing the formula of the compound followed by a dot and the number of water molecules associated with the compound. For example, CuSO4 • 5H2O represents copper(II) sulfate pentahydrate, which contains five water molecules for every one copper sulfate molecule.

How do you calculate the percent water in a hydrate?
To calculate the percent water in a hydrate, you first determine the mass of water in the hydrate by subtracting the mass of the anhydrous compound from the mass of the hydrate. Then, divide the mass of water by the total mass of the hydrate and multiply by 100 to get the percentage.
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.
Is methyl hydrate the same as methane hydrate?
No, methyl hydrate is another term for methanol, while methane hydrate is a solid form of methane trapped in a lattice of water molecules. They are distinct chemical compounds with different properties and uses.
A compound that has a specific number of water molecules bound to its atoms?
The term for a compound that has a specific number of water molecules bound to its atoms is a hydrate. In a hydrate, water molecules are typically attached to the compound through weak chemical bonds known as hydrogen bonds. The number of water molecules in a hydrate is represented by a numerical prefix in the compound's name, such as in CuSO4•5H2O, where there are five water molecules bound to each copper sulfate molecule.
How many moles of water are associated with each mole of methane hydrate if a sample has 160cm3 methane and 1000g of water ar room temperature and pressure?
For each mole of methane hydrate, there are 5.75 moles of water associated with it. In this case, since you have 160 cm³ of methane and 1000g of water, we first convert 160 cm³ of methane to moles, which is 5.62 moles. Then we calculate the moles of water based on the ratio 1:5.75 for methane to water in methane hydrate, which gives us approximately 32.3 moles of water associated with the 5.62 moles of methane.
