Four gases were combined in a gas cylinder with these partial pressures: 3. 5 atm N2, 2. 8 atm O2, 0. 25 atm Ar, and 0. 15 atm H

aksik [14]

The total pressure of the gas has been 11.9 atm.

The partial pressure has been the pressure exerted by the individual gas in the mixture.

According to the Dalton's law of Partial pressure, the pressure of the gas has been the sum of the partial pressure of each gas in the mixture.

<h3 /><h3>Computation for the pressure of gas</h3>

The given gas has partial pressure of Nitrogen, $P_{N_2}=3.5\;\rm atm$

The partial pressure of Oxygen, $P_{O_2}=8\;\rm atm$

The partial pressure of Argon, $P_{Ar}=0.25\;\rm atm$

The partial pressure of Helium, $P_{He}=0.15\;\rm atm$

The total pressure, (<em>P</em>) of the gas has been given as:

$P=P_{N_2}\;+\;P_{O_2}\;+\;P_{Ar}\;+\;P_{He}\\
P=3.5\;+8\;+\;0.25\;+\;0.15\;\text{atm}\\
P=11.9\;\rm atm$

The total pressure of the gas has been 11.9 atm.

Its atoms contain 3 protons and 4 neutron(s).<br> Express your answer as an isotope.

velikii [3]

Answer: A=7 for the isotope with 4 neutrons.

Explanation:A lithium atom contains 3 protons in its nucleus. Notice that because the lithium atom always has 3 protons, the atomic number for lithium is always Z = 3. The mass number, however, is A = 6 for the isotope with 3 neutrons, and A = 7 for the isotope with 4 neutrons.

Why would "not flammable" be a chemical property rather than a physical property ?

Dmitrij [34]

When something is flammable, it burns and burning is a chemical property since the compounds are being broken down and gas is released. If something is non-falammable, it would then be a chemical property as well since the chemical makeup would not be broken by a flame. (I apologize if my answer is a bit broad or unspecific)
