Answer:
-32821.2 J (negative sign implies that work is done by the system)
Explanation:
The expression for the calculation of work done is shown below as:
Where, P is the pressure
is the change in volume
From the question,
= 18.0 - 1.00 L = 18.0 L
P = 18.0 atm
Also, 1 atmL = 101.3 J
So,
(negative sign implies that work is done by the system)
Answer:
Rutherford established the nuclear theory of the atom with his gold-foil experiment. When he shot a beam of alpha particles at a sheet of gold foil, a few of the particles were deflected. He concluded that a tiny, dense nucleus was causing the deflections.
Answer:
Henry Moseley.
Explanation:
Hello,
Henry Moseley's work stated that it is better to organize the periodic table in the light of the atomic number (which accounts for the amount of protons and electrons) instead of the atomic mass, because atomic numbers are not arbitrarily assigned as long as they have the aforesaid physical basis.
Best regards.
