What Abnormal Results Mean. An abnormal result means you have ketones in your urine. The results are usually listed as small, moderate, or large as follows: Small: <20 mg/dL. Moderate: 30 to 40 mg/dL. Large: >80 mg/dL. Ketones build up when the body needs to break down fats and fatty acids to use as fuel. This is most likely to occur when the.

Class 9 Question When we keep acetone and ether on our palm we feel cold because they absorb the latent heat for vaporization from our palm and evaporates which causes cooling. Hence, our palm feels cold when we put some acetone or petrol or perfume on it.

Summary Acetone is a colorless solvent. Solvents are substances that can break down or dissolve other materials. In the household, people may come across acetone in products such as nail.

Mechanism Ketogenesis occurs primarily in the mitochondria of liver cells. Fatty acids are brought into the mitochondria via carnitine palmitoyltransferase (CPT-1) and then broken down into acetyl CoA via beta-oxidation.

(a) what type of deviation is shown by a mixture of ethanol and acetone? Give reason (b) A solution of glucose (molar mass =180 g mol−1) m o l - 1) in water is labelled as 10% (by mass) what would be the molality and molarity of the solution ?

Solution When l-chloro-2, 4-dinitrobenzene is heated with aqueous alkali (aq. NaOH ), 2, 4-dinitro sodium phenoxide is formed which on hydrolysis with dilute HCl gives 2, 4-dinitrophenol. Two molecules of benzaldehyde react in the presence of 50‰ KOH, the products formed are benzyl alcohol and potassium benzoate.
