Answer:
Ferric chloride test
Explanation:
The ferric chloride test can be used to detect metabolites in urine in case of inborn error of metabolism such as phenylketonuria. Compounds such as phenylpyruvate increase in plasma and are excreted out via urine. Also, it can be used to detect salicylates in urine, quick diagnostic test for aspirin overdose.
Elements. Elements cannot be further separated as they are the most basic substances.
Answer:
Increasing temperature increases the solubility of most salts, but not all. The reason for the differences is that dissolution involves three steps: breaking bonds of salt in the lattice; forming cavities in water the same size as the ions; interacting the salt with water in the cavity.
Because of the ammount of water and the boling point of the Ganga River has changed due to the mixtures of different kind of chemicals and acids
89.1% Au
The molar mass of Au2O3 is 2(196.97) + 3(16.00) = 441.94 g/mol
The mass percent of Au is therefore 2(196.97) / 441.94, which is 393.94/441.94 = 0.891 —> 89.1%
