Why water cant be used as a solvent for infrared spectroscopy? Why does gasoline not dissolve in water? Why should you never use a beaker for recrystallization? How can acetone (2-propanone) be synthesized from alcohol? Why does water, oil, acetone and isopropanol have the same concave m...
Why do fatty acid come in chains of even-numbered hydrocarbons? Why is boiling water not a chemical reaction? Why are chemical elements important? Why does ethanol have a higher boiling point than diethyl ether? Explain scientifically why we don't run out of the important gases that we need...
~~10. From the chromatography lab, which pigments were soluble in the acetone? (5 points) The pigments present in the lab were Carotene, Xanthophyll, Chlorophyll a, and Chlorophyll b. ~~11. The earth's early atmosphere did not contain oxygen. This changed dramatically once the early cells ...
Why is heptane insoluble in water?Question:Why is heptane insoluble in water?Solubility:The tendency of a matter to get completely mix in a solvent to produce a homogenous mixture is named as solubility. This ability is based on "like dissolve like" principle. Hydrocarbons do not form solution...
Acetone is a chemical made up of two methyl groups (CH3) and a carbonyl group (C=O). It is a common substance found in nail polish remover, and it is also used in labs to clean containers. Its use in cleaning is partly because it can dissolve substances that water and soap alone ...
Why does fatty acids solubility decrease in a non-polar solvent (such as benzene)? Explain why soaps are more water-soluble than fatty acids are. Why do salts dissolve in water? Explain why coconut oil is a liquid triglyceride even though most of its fatty acid components are saturated. ...
Why is acetone used to rinse out wet glassware? Briefly explain why you should not add boiling chips to a boiling liquid. What factors affect re-crystallization? Explain why it is not a good idea to cook acidic foods such as tomatoes in aluminum cookware. Why does...
Why does gasoline not dissolve in water? Why may hydrogen not be advantageous as a fuel? Why is it that it is safe to eat olive oil, corn oil, canola oil, etc. but not diesel oil or something like that? What is the reason in a chemical structural sense?
Why does a racemic mixture not rotate the light? Why doesn't sulphur dioxide directly dissolve in water? Give two reasons why the crude product in most reactions is not pure. Why do the molecules that have structures such as H_2C=C=CH_2 or HO-CH=CH_2 are unstable?
Why do non-polar substances not dissolve in water? Explain why the solubility of gases in water decreases at higher temperatures whilst the solubility of most ionic solids increases. Why will acetone evaporate more quickly than water? Is the vapor pressure of the two substances different?
