electrolytes and soluble‚ demonstrating that that part of our conclusion was correct. However‚ two ionic compounds were shown to be acids (Copper(II) Sulfate and Potassium Carbonate). All but one of the molecular compounds were soluble‚ the exception being Paraffin Wax. However‚ we were wrong in our hypothesis that no molecular compounds were electrolytes‚ as the two acids (Sulfuric acid and Hydrochloric acid) were electrolytes. Our hypothesis that the molecular compounds could be acids or bases was correct

liquids‚ the reverse process can be used to separate gases by liquefying components using changes in temperature and/or pressure. Distillation is used for many commercial processes‚ such as production of gasoline‚ distilled water‚ xylene‚ alcohol‚ paraffin‚ kerosene‚ and many other liquids. Types of distillation include simple distillation (described here)‚ fractional distillation (different volatile ’fractions’ are collected as they are produced)‚ and destructive distillation (usually‚ a material

Carbon and Its Compounds Carbon: Introduction Atomic Number: 6 Electronic Configuration: 2‚ 4. Valence electrons: 4 Property: Non-metal Abundance:- Carbon is the 4th most abundant substance in universe and 15th most abundant substance in the earth’s crust. Compounds having carbon atoms among the components are known as carbon compounds. Previously‚ carbon compounds could only be obtained from a living source; hence they are also known as organic compounds. Bonding In Carbon:- The Covalent

Studies show that most incidents affect children and adolescent people. Commercially‚ there are various products of mosquito repellents readily available for consumers but most of them are highly made from chemicals that are damaging to the skin and are expensive‚ making it less accessible to most people.

The reaction between alpha-amino acid and ninhydrin involved in the development of color are described by the following five mechanistic steps: alpha-amino acid + ninhydrin ---> reduced ninhydrin + alpha-amino acid + H2O alpha-amino acid + H2O ---> alpha-keto acid +NH3 alpha-keto acid + NH3 ---> aldehyde + CO2 Step (1) is an oxidative deamination reaction that removes two hydrogen from the alpha-amino acid to yield an alpha-imino acid. Simultaneously‚ the original ninhydrin is reduced
