How do you separate a mixture of potassium chloride and iodine give details?
To separate a mixture of potassium chloride and iodine, you can use a process called sublimation. Iodine can be sublimed by heating the mixture, causing it to change from a solid directly to a gas. The iodine vapor can then be collected and condensed back into solid iodine. The remaining potassium chloride will be left behind as a solid.
Give you an examples of sublimation in science?
An example of sublimation in science is dry ice, which is solid carbon dioxide that changes directly into carbon dioxide gas when heated. Another example is the process of freeze drying, where water is removed from a substance by sublimation under low pressure and temperature conditions.
Is it tru that iodine reacts with starch to give a red color?
No when you but iodine with sarch for example a potato the starch reacrs with the iodine and it turns black
What does iodine solution test for?
For starch, which will give a deep blue-black color.
Solid aluminum reacts with solid iodine to produce solid aluminum iodide?
No. Al+I doesn't equal Al2O3 It will yield aluminum iodide AlI3
What do you meant by sublimation also give example?
Sublimation is the process of direct transformation of a solid in a gas: examples are iodine, naphthalene, dry ice, camphor.

What is sublimation and give an example?
Sublimation is when a solid goes to a gas when heated rather than going to a liquid first. At normal pressure solid carbon dioxide and iodine go directly to vapor without going to a liquid first.
What is sublimation and give an example of a substance that sublimes?
If zinc chloride is heated strongly the solid will sublime.
Give you an examples of sublimation in science?
An example of sublimation in science is dry ice, which is solid carbon dioxide that changes directly into carbon dioxide gas when heated. Another example is the process of freeze drying, where water is removed from a substance by sublimation under low pressure and temperature conditions.
Can you give me 5 examples of sublimation?
Dry ice sublimating from solid to gas without melting into a liquid. Mothballs gradually evaporating in a closet without leaving behind a liquid residue. Snow disappearing into vapor without melting into water. Freeze-dried food removing moisture through sublimation to preserve flavor and texture. Iodine crystals turning directly into purple vapor without melting first.
How do you make a 3-d iodine atom model?
To makea model of iodine you'll need lots of spheres the same size. Join them together in pairs to represent the iodine molecule I2. The bond you are making here is a covalent bond and won't break if your iodine becomes a gas. You need a whole collection of iodine molecules and sit them down together as close as you can get them to represent solid iodine. The forces holding them together are an example of van der Waals forces. These forces are strong enough to make iodine be a solid at room temperature.... but if you give them some energy by shaking your model, they should start to leap about as you solid iodine becomes a gas. This change is called sublimation.
What is the balanced equation for aluminium reacting with iodine to give solid aluminium iodine?
2Al + 3I2 -> 2AlI3
Can you give me 3 examples of sublimation?
Sublimation - a phase change from solid to gas without passing through a liquid phase - at normal atmospheric pressure can be observed with solid carbon dioxide (dry ice), iodine crystals when heated (give off violet vapours) and napthalene moth balls (give off characteristic odour).
Does ground nut seed give blue black colour with iodine solution?
Yes, groundnut seeds typically give a blue-black color with iodine solution due to the presence of starch in the seeds. When iodine comes in contact with starch, it forms a dark blue to black complex.
Why doesn't the cellulose give blue color with iodine?
Cellulose does not give a blue color with iodine because it is a polysaccharide composed of glucose units linked together by beta-1,4-glycosidic bonds. Iodine reacts with the helical structure of starch, forming a blue-black complex due to the presence of amylose chains. Cellulose lacks the necessary structure for this reaction to occur.
Is it tru that iodine reacts with starch to give a red color?
No when you but iodine with sarch for example a potato the starch reacrs with the iodine and it turns black
