(a)
Interpretation:
A black powder is placed in a long glass tube and hydrogen gas is passed into the tube so that hydrogen sweeps out all other gases. The powder is heated with Bunsen burner. It turns into red-orange and water vapour can be seen condensing at the tip of the tube. The red-orange colour remains after the tube is cooled.
The original black substance is an element or not has to be explained.

- This organic molecule is dissolved in a basic aqueous solution: O ? olo RET A short time later sensitive infrared spectroscopy reveals the presence of a new C-OH stretch absorption. That is, there Ar must now be a new molecule present with at least one C - OH bond. In the drawing area below, show the detailed mechanism that could convert the molecule above into the new molecule. $ Add/Remove steparrow_forwardSo the thing is im trying to memorize VESPR Shapes in order to be able to solve problems like so, and I need help with making circles like the second image that's in blue or using an x and y axis plane in order to memorize these and be able to solve those type of problems. Especially like the ones given in the top / first image. (180 , 120 , 109.5) Can you help me with this.arrow_forwardDon't used hand raiting and don't used Ai solutionarrow_forward

The growth and production of cells, called cell proliferation, is known to involve an enzyme called protein farnesyltransferase (PFTase). It is thought that inhibitors pf PFTase may be useful as anticancer drugs. The following molecule showed moderate activity as a potential PFTase inhibitor. Draw all stereoisomers of this compound.
