4157 J work is done by the gas , If 2 moles of helium undergo a temperature increase of 100 K at constant pressure.
<h3>What are Noble Gases ?</h3>
The noble gases are helium, argon, krypton, xenon, and radon, in order of their mass.
They are called noble gases because they are so majestic that they do not react with anything in general.
The work done can be calculated by the formula
Q=n Cp ΔT
Cp= ( 1+ f/2)R
R= 8.3144598 J. mol-1.
Cp = (1+3/2) * 8.314
Cp = 5*8.314/2
Q= 2 * 5 *8.314 *100/2
Q = 4157 J
Therefore 4157 J work is done by the gas , If 2 moles of helium undergo a temperature increase of 100 K at constant pressure.

Answer:
The epipelagic zone reaches from the surface of the ocean down to around 650 feet. This is the zone most exposed to light, and as such is host to the highest concentrations of the ocean's life. There are thousands of animals that roam this zone, including dolphins, most sharks, jellyfish, tuna and corals.
(From Internet I’m being honest)
Answer:
Velocity
Explanation:
Synonyms are words/phrases that mean the exact or nearly exact same in meaning. Velocity, pace, and speed all mean close to the same thing as far as the rate in which something is moving.
Researchers have shown that when really small particles are close to each other like in a nebula, they are attracted to each other due to electromagnetism (from static electricity) since the masses are too small for gravity to really matter. However, the answer is probably gravity, electromagnetism only played a small role in the very beginning when nothing had enough mass. After that, gravity caused everything to condense and gravity did a better job once everything had enough mass for gravity to matter.
I hope this helps, let me know if anything is unclear in the comments.
Answer:
V3− B) A nonmetal that gained three electrons
X− A) A nonmetal that gained one electron
Y+ C) A metal that lost one electron
Z3+ D) A metal that lost three electrons
Explanation:
As per the Octet rule, each atom must have eight electrons in its outermost shell.
The non-metals gain electrons while reacting to reach the configurations of noble gas as they possess lower Ionization ability and higher electro-negativity. Thus, they will have a negative charge(V3 -, X-)
Metals, on the other hand, lose electrons to reach a stable octet configuration due to the higher electro-positivity and lower electron affinity. Therefore, they will have a positive charge(Y+, Z3+).
