How many grams of chlorine must be added to a balloon containing 8.00 grams of helium to double its volume?

1 answer:

4 0

The mole number of helium is 8/4=2 mol. Under same condition, the volume of gas is related to the mole number of the gas. So the mole number of chlorine is also 2 mol which is 142 g.

What happens when non-metal atoms ionize? A) They lose electrons B) They gain electrons. C) They lose 2 electrons. D) They do no

nignag [31]

When non-metal atoms ionize they gain electrons. Some examples of this are the halogen elements: F, Cl, Br and I, each, can gain one electron from the respective anions, F-, Cl-, Br-, and I-. O and S, may gain two electrons to form the anions O2- and S2-. This is due to the fact that those elements only need one (in the case of the halogens) or two (in the case of O and S) electrons to reach the most stable configuration of the closest noble gas (with the last shell of electrons full), so they are ready to gain those electrons and form the corresponding ions.

A gas has a volume of 1.75L at -23C and 150.0kPa. At what temperature would the gas occupy 1.30L at 210.0kPa?

Katen [24]

Answer:

T2 = 260 K

Explanation:

Given data:

P1 = 150.0 k Pa

T1 = (-23+ 273.15) K = 250.15 K

V1 = 1.75 L

P2 = 210.0 kPa
