Answer:
W = 234 J
Explanation:
Initial volume of air is given as
finally it is expanded isothermally to new pressure of 101.3 kPa
now by isothermal expansion we know
So work done in above process is given as
Now it is cooled to initial volume at constant pressure
so here in this case work done is given as
Now total work done is given as
Answer:
Speed of the electron will be
Explanation:
We have given that charge on electron
Mass of electron
Potential difference =
Now according to energy conservation
Hi!
The answer would be ~ 3.58
<h3>Explanation</h3>
You will need to use the simple formula of finding the number of moles, given the mass of the compound, which is:
number of moles of compound = mass of compound / Mr of compound
The mass in this equation is the mass of the compound you have/ are considering.
The Mr is the sum of the atomic masses of each element in the compound.
<u><em>To proceed with this, you need to have two of the following values:</em></u>
Mass : 340g
Mr of MgCl2 : 95
Number of moles : ?
<u><em>Substituting the respective values in the equation:</em></u>
number of moles = mass / Mr
number of moles = 340 / 95
number of moles = 3.58
Hope this helps!
The answer yo this question is:
B-"Nitrogen, Arsenic, and Antimony"
Because its the only one out of all of the rest of the list that it contain properties that have similar element

Increasing the separation distance between objects decreases the force of attraction or repulsion between the objects. And decreasing the separation distance between objects increases the force of attraction or repulsion between the objects. Electrical forces are extremely sensitive to distance.
