Why is the net charge of a neutral atom zero?

nikitadnepr [17]

Answer:

Explanation:

The positive (protons) and negative (electrons) charges balance each other in a neutral atom, which has a net zero charge. Because protons and neutrons each have a mass of 1, the mass of an atom is equal to the number of protons and neutrons of that atom.

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.
