Predict the structure of the enamine product in the reaction below and show the last step of the mechanism.
Beta carotene is the most important of the A vitamins. Its molar mass (g/mol) can be determined by measuring the osmotic pressure generated by a given mass of beta carotene dissolved in the solvent chloroform. Compute the molar mass of beta carote..
Problem- Write equations for loss or gain of electrons by atoms that result in formation of the following ions.
A beaker contains a solution that is 0.50M in Au3+ ion and 0.25 M in Ag+ ion. A solution of sodium chloride is slowly dripped into the beaker with stirring. Which ion will precipitate first, the gold or the silver
The decomposition of urea in 0.1 M HCl is first order in urea and first order overall. When [urea] = 0.200 M , the rate at 61.0 °C is 8.56 x 10-5 M/s. What is the concentration of urea in this solution after 4751 s if the starting concentration is 0..
