<u>Answer</u>:-
Try this formula:
W= Fd
F = W by d
Explanation:-
(Note: A newton-meter is the same thing as a joule, so the units for work are the same as those for energy – joules).

The structures represented by A in the image are the products of the acid base reaction shown.
In organic chemistry, an important aspect of study is reaction mechanisms. Reaction mechanisms often involve movement of electrons shown as arrows. We must diligently follow the movement of these arrows in order to get the products of the reaction correctly.
If we follow the arrows in this case, we will discover that the methoxide ion picks up the proton as shown and there is a movement of electrons from the carbon bearing the 0-H group to the adjacent carbon atom. While a double bond is formed between carbon and oxygen.
These electron movements yield the products shown in (a) in the image attached to the question.

Answer: The correct answer is 'temperature will get doubled that is option D.
Explanation:
Suppose the volume of the bubble is V, at temperature T and Pressure exerted by atmosphere P.
When bubble is blown with more air until the volume doubles the initial volume:
The new volume of the bubble = V'=2V
The new Temperature of the air inside the bubble will change to T'.
And the atmospheric Pressure remains same.
According Charles law:
(At constant Pressure)
So, this means that temperature will get 2 times the initial temperature of the gas.
Hence, the correct answer is 'temperature will get doubled that is option D.
Answer:
0.0630
Explanation:
The molar mass of urea = 60 g/mol
we all know that:
Then; the number of moles of urea
=
= 0.0667 mol
Similarly; the number of moles of methanol
=
= 0.9988 mol
The total number of moles = (0.0667 + 0.9988) mol
= 1.0655 mol
Finally,the mole fraction of urea =
=
= 0.0630
