What happens to gases when they lose heat Do they condense into liquids?
Depends on how much heat they loose and which gas (or mixture of gasses) they are. But yes, cool most gasses enough and they liquify (and then solidify if cold enough).
Why the mixture of the metal fillings and sulfur becomes chemical change when heat was applied?
Applying heat to the mixture causes a chemical reaction to occur: 2Fe + 3S -> Fe2S3
How can you get hydrogen from a mixture of hydrogen and hydrogen chloride gas?
Cool the mixture for minus temperature.HCl liquidize first.Remove HCl and you get only H2.
How you would prepare a sample of solid sodium chloride from sodium hydroxide solution and hydrochloric acid?
Add concentrated solution of Hydro chloric acid to the solution of sodium hydroxide till mixture becomes neutral (checked by litmus) then heat the mixture , when a little amount of water is left allow to cool the mixture , the crystals of sodium chloride settelted down filter and dry the crystals.
How can you separate a mixture of iron filings sand and camphor?
we separate it by sublimation. we put the mixture in a funnel and we heat it. the camphor evaporates in gaseous form leaving sand behind
How will you separate iodine and salt mixture?
heat the mixture iodine will sublime collect the iodine vapour separately and cool
Do geckos like the heat?
Yes, but you should still have a cool place for them to lie. They like a mixture.
How can you separate the mixture of sugar and camphor?
Camphor will sublime when heated mildly (sugar will not). Heat the mixture mildly, collect the sublimate separately, cool the sublimate to get camphor.
Why should we cool the mixture in haber process?
To ensure that you have the more product which will be produced because the equilibrium will shift to produce it. This will produce heat and also more chemical product that you want in the equilibrium mixture.
How do you stop cream from splitting while cooking?
If you mean curdling , you need to heat the cream slowly and not add it to a hot mixture when it is cool. If cream is needed to be added to a hot mixture, slowly heat the cream to mixtures temperature in a separate pot and add it when it is hot.
Can sugar be obtained by crystallisation?
Yes. As sugar can be charred by heat, we can't use evaporation. In crystallization, the mixture is heated until a concentrated mixture is obtained. Then the mixture is left to cool so that the excess solid particles in the mixture will precipitate out as crystals. eg. sugar from sugar solution
