Answer:
See explanation and image attached
Explanation:
The reaction between benzophenone and phenylmagnesium bromide is a Grignard reaction.
A Grignard reagent is any alkyl magnesium halide compound. In this case, the Grignard reagent is phenylmagnesium bromide.
Reaction of Grignard reagent with a ketone yields all alcohol. Thus, the reaction of benzophenone with phenylmagnesium bromide yields triphenyl methanol.
The mechanism of the reaction and all electron movements are shown in the image attached to this answer.

In which season is the sun closest to the earth?Answer Summer
Answer:
Examples of substances insoluble in water: oil, acetone, ether
Explanation:
Such examples of substances are non-polar and do not dissolve in water (polar compound). The classic example is oil floating in water (this happens because oil has a lower density than water).
Answer:
A Light Emitting Diode (LED) is a solid-state semiconductor device that converts electrical energy directly into light. On its most basic level, the semiconductor is comprised of two regions.
Explanation:
In the answer
Answer:
Option D.
Explanation:
Let's apply the Ideal Gases law to solve the problem.
P . V = n . R . T
First of all we convert the temperature value from °C to K
77°C + 273 = 350K
and the pressure from mmHg to atm
623 mmHg . 1 atm/760 mmHg = 0.82 atm
We replace data: 0.82 atm . 17.5L = n . 0.082 L.atm/mol.K . 350K
(0.82 atm . 17.5L) / (0.082 L.atm/mol.K . 350K) = n
0.50 moles = n
These are the moles that corresponds to 22 g of the gas, so the molar mass will be → 22g / 0.50 mol = 44 g/mol
That molar mass corresponds to CO₂ → 12 g (C) + 16 g (O) . 2 = 44 g/mol
