All answers are correct except option b
Distillation is a useful separating technique because every compound has a unique boiling point. Distillation takes advantage of a compound's boiling point to separate it from other compounds.
Panning.
Flotation.
Check it out yourself freak. I'm joking. It Gravity separating.
Yes, crystallization is a method of separation; a very known application is the separation of salt from sea waters.
Ion exchange chromatography would be most suitable for separating glucosamine from glucuronic acid. This technique separates compounds based on their charge differences, and since glucosamine and glucuronic acid have different charges, they can be effectively separated using this method.
Decanting is basically a fancy word for "pouring." It's not effective at all for suspensions where the suspended phase is still in suspension; it may be effective in some cases after the suspended phase settles out.
Industrial decisions are made based on cost / benefit analysis. Maximum profit for making a certain amount of the substance.
First decant the water - the sand will be left behind. Then evaporate the water and the salt will be left behind.
The technique commonly used to find the relative atomic mass (Ar) of an element is mass spectrometry. This technique involves ionizing the sample, separating the ions based on their mass-to-charge ratio, and then detecting and quantifying the abundance of different isotopes to calculate the average atomic mass.
The method used for separating substances dissolved in the same liquid is called fractional crystallization. This technique involves slowly cooling the solution so that different substances crystallize out at different temperatures, allowing them to be separated based on their solubility.
One common technique for separating salt particles is evaporation. By dissolving the salt in water, then allowing the water to evaporate, the salt particles will be left behind. Another technique is filtration, where a porous material is used to separate the salt particles from the liquid.
