The density of gas particles in a section of Earth’s atmosphere decreases. Which of the following is the most likely explanation

Bad White [126]

<span>This is due to the fact that the air pressure in that certain section of Earth’s atmosphere decreased. As density of gas particles decreases as air pressure decreases. Therefore, density of gas particles and air pressure have a direct relationship. An increase in air pressure would then effect to an increase in gas particles. </span>

Determine the density of nh3 gas at 435k and 1.00atm

goldenfox [79]

We assume that this gas is ideal. Therefore, we can use the ideal gas equation which is expressed as:

PV=nRT

We manipulate this equation to give us an expression which will correspond to density. We do as follows:

PV= nRT
P/RT = n/V where n = m/MM
P(MM) /RT = m/V = density
Density = 1.00 (17.03) / 0.08206 (435)
Density = 0.48 g / L

Assuming an ionization efficiency of 13.0%, how many such photons are needed to ionize 1.00×1016 atoms?

sammy [17]

Answer:

7.69x $10^{16}$

Explanation:

The ionization is the energy necessary to transform an atom in an anion. So, it's the energy it requires to gain an electron.

This ionization occurs for the photoelectric effect - the emission of electrons by metal using photons. So, if the efficiency is 100%, 1 photon can ionize 1 atom, but for an effficiency of 13.0%:

N = $\frac{1.00x10^{16}}{0.13}$

N = 7.69x $10^{16}$

Where N is the number of photons.
