Gallic acid (GA), also known as ellagic acid, is an organic acid found in various sources such as gallnuts, sumac, lacquer tree, oak bark, and tea leaves. It is widely used in the production of blue-black ink and leather, as well as a photographic developer. Gallic acid also serves ...
Specifically, Masteron is the DHT hormone that has been structurally altered by the addition of a methyl group at the carbon 2 position, This protects the hormone from the metabolic breakdown by the 3-hydroxysteroid dehydrogenase enzyme, which is found in the skeletal muscle. It also greatly ...
2. What is the effect on the boiling and melting point of a compound that contains a carboxyl group? 3. Why is the carboxyl group considered to be a weak acid? 4. When the carboxyl group is deprotonated, how does it remain relatively stable? 5. What are some compounds in our eve...
What is the functional group in acetic acid?Functional Group:The functional group in an organic compound is the group plays an important role in the physical and chemical properties of the compound.

This is pale yellow and is in crystalline form. It is insoluble in water.123g/mol is found to be the molar mass of nitrobenzene.Answer and Explanation: Nitration of benzene is the reaction of benzene with concentrated Nitric acid. Around 323-333K temperature is maintained during the reaction...
METTLER TOLEDO's reference substances such as benzophenone, vanillin, benzoic acid and potassium nitrate, provide certified temperature values that can be used for temperature calibration of METTLER TOLEDO's DP70 and DP90 furnaces over a broad range of temperature. Caffeine and saccharine ...
The ACFs differ significantly in their surface functional groups. CACF owns the highest concentrations of Conclusions The comparison of adsorption affinities on various ACFs showed that the order in sensitivity to carbon surface chemistry is PFOA ≫ octanoic acid > phenanthrene. On the other hand, ...
