Why do you use marble and not chalk to make floors?
Chalk dissintegrates/dissolves
When chalk dust dissolve in water it is called?
When chalk (the mineral) dissolves in water, it's called "limewater".
Is ethanol soluble in kerosene?
ethanol (i.e ethyl alcohol) is a polar solvent. So ethanol is soluble in water. But Kerosene is non-polar solvent. Like dissolves like. This phenomenon is used here. Kerosene can dissolve non-polar solvents like naphthalene, which is a non-polar solvent.
Why do mothball powder and margarene dissolve in kerosene but not in the water?
Because "like dissolves like" eg. polar substances dissolve polar substances. Mothball powder, margarine, and kerosene are all non-polar. Water however is polar, so the mothball powder and margarine cannot dissolve in it.
Why kerosene is not a fossil fuel?
Fossil fuel is kerosene. Of kerosene oil condensate.

Why is powdered chalk more like a liquid than a lump of chalk is?
because it consists of small particles that are similar to liquid. Even if we add water to a powdered chalk, it dissolves easily whereas a lump of chalk is harder to dissolve in water.
Why does cola dissolve chalk?
Chalk is calcium carbonate. Cola is an acid. When these two compounds mixed, hydrogen carbonate is formed. This compound is water soluble, and thus chalk mixed with and acid like cola dissolves in water.
When chalk dissolves in water how can it be collected?
Chalk particles can be collected by using a filtration process. A filter paper or a fine sieve can be used to separate the dissolved chalk particles from the water. The water can then be evaporated to obtain the solid chalk residue.

What solid dissolves best in water are twenty degrees Celsius salt sugar iodine chalk or urea?
Sucrose is the most soluble.
What soda dissolves chalk fastest?
None. It will depend on the initial temperature of the soda, not the brand.
Why is it that sodium chloride is insoluble in kerosene?
When sodium chloride dissolves in water it does so because the positive and negative ions are attracted to the polar water molecules. Benzene molecules are not polar so there is much less attraction.
Will salt dissolve faster in vinegar or salt?
Depends on the pH of the water but it would dissolve faster in fresh water because there isn't as much stuff in solution. true... but it took me about 8.30 seconds to dissolve with the perfect pH.....

What is happening in the ocean?
Increased carbon dioxide in the atmosphere can become dissolved in the ocean forming an acid called carbonic acid. This acid results from carbon dioxide combining with water and this also contributes to the acidity of soda. The increased acidity of the ocean makes it more difficult for animals and corals to form shells which are made of calcium carbonate, the same material as chalk since calcium carbonate dissolves in acid. As a experiment, try adding lemon juice to a little piece of chalk or chalk powder. You can see how the acid from the lemon juice dissolves the chalk and bubbles from this. These bubbles are carbon dioxide and that the chalk or chalk powder disappears. This reaction happens to a much slower extent to seashells or the shells that corals try to form making more difficult for corals and certain other sea creatures.
