With such huge increases in population, why has there not been a direct and equivalent increase in urban development (i.e., why

is it such a small proportion of habitable land use)?
plz help

He equilibrium constant (KP) is 0.21 at a particular temperature for the reaction:

lorasvet [3.4K]

Explanation:

We will use the following equation,

$Q_{p} = \frac{(P^{2}_{NO_{2}}{P_{N_{2}O_{4}}$

(a) Now, we will calculate the value of $Q_{p}$ as follows.

$Q_{p} = \frac{(0.225)^{2}}{0.134}$

= 0.377

As, the $K_{p}$ is 0.21 (which is smaller than the value) this means that equilibrium will shift to the left .

(b) $Q_{p} = \frac{(0.086)^{2}}{0.064}$

= 0.1155

Here, $Q_{p}$ is smaller than $k_{p}$ which means that the equilibrium will shift to the right.

(c) $Q_{p} = \frac{(0.13)^{2}}{0.142}$

= 0.119

Here, $Q_{p}$ is smaller than $k_{p}$ which means that the equilibrium will shift to the right .

(d) $Q_{p} = \frac{(0.173)^{2}}{0.142}$

= 0.21

Since, here the value of $Q_{p}$ comes out to be equal to the given value. Therefore, this reaction is at equilibrium.

(e) $Q_{p} = \frac{(0.151)^{2}}{0.062}$

= 0.36

Here, $Q_{p}$ is higher than $k_{p}$ the reaction will shift to the left.

Why is helium nucleus containing no neutrons is likely to be unstable

jolli1 [7]

<span>A Helium nucleus is likely to be unstable if it has no neutrons because the remaining protons will repel electromagnetically and basically cause the atom to fall apart. The neutrons could have helped in holding everything together, and not make the protons repel.</span>

Which element would most likely have a positive electron affinity?

krok68 [10]

I believe the correct answer from the choices listed above is the first option. The element that would most likely have a positive electron affinity would be sodium, Na. Electron affinity is defined as the change in energy of a neutral atom when an electron is added to the atom.

A sample of krypton gas collected at a pressure of 1.31 atm and a temperature of 26.0°C is found to occupy a volume of 23.3 lite

djyliett [7]

Mol of Kr gas = 1.244

<h3>Further explanation</h3>

In general, the gas equation can be written

<h3> PV=nRT </h3>

where

P = pressure, atm

V = volume, liter

n = number of moles

R = gas constant = 0.08205 L.atm / mol K

T = temperature, Kelvin

P=1.31 atm

V=23.3 L

T=26+273=299 K

mol of sample :

$\tt n=\dfrac{PV}{RT}=\dfrac{1.31\times 23.3}{0.08205\times 299}=1.244$
