that's instrument picture there is an manometer
Answer:
The hydrogen can be gotten from the added Acid or water during "workup".
Explanation:
Basically we can say that the reaction describe in this question is a Reduction reaction because of the chemical compound called sodium borohydride. In the reaction described above we can see that there is a Reduction of ketone to alcohol by the compound; sodium borohydride.
For the reduction Reaction to occur the C-O bond must break so as to enable the formation of O-H bond and C-H bond.
So, "the reaction mixture is treated with water and H2SO4 to produce the desired alcohol", thus, the oxygen will definitely pick up the hydrogen from H2SO4 or H2O.
What are the answer choices???
According to the plum pudding model of the atom proposed by J.J. Thomson, the atom was considered to be a positive charge sphere in which electrons (negatively charged) are embedded in order to balance the positive charge.
According to Rutherford’s gold foil experiment, when he bombarded particles to the gold foil he observed that most of the particles went through, some of them got scattered in various directions, and few are deflected back to the source. Hence, this experiment shows that the plum pudding model was incorrect as; if there was the symmetrical distribution of the charges then all the particles will pass through without any deflection.
