How do you prepare a pure sample of dry carbonate using solution of ammonium carbonate?
To prepare a pure sample of dry carbonate using a solution of ammonium carbonate, you would need to first evaporate the solution to dryness to obtain solid ammonium carbonate. Then, heat the solid in a crucible to decompose it into ammonia, carbon dioxide, and water. Finally, collect the carbon dioxide gas and purify it to obtain the pure dry carbonate.
Why dry sample is use in determination of crude fat?

How would you prepare a sample of pure dry ammonium nitrate?
To prepare a sample of pure dry ammonium nitrate, dissolve ammonium nitrate in water to form a saturated solution, then allow the solution to cool and crystallize. Filter and dry the resulting crystals to obtain pure dry ammonium nitrate.
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.
Can people breathe methane?
Yes, but it is very dangerous to the human body, in that high enough concentrations in the air can result result in suffocation.
