Answer:

The overall charge of an atom is zero. ... The charge from a proton or electron are of equal strength, therefore if an atom has an equal number of protons and electrons, it will be electrically neutral. However, atoms are not always electrically neutral, in which case they are called ions.

Sorry if it's wrong!!!!

At 500°C the equilibrium constant, Kp, is 4.00 × 10–4 for the equilibrium: 2HCN(g) H2(g) + C2N2(g) What is Kp for the following

Andrews [41]

<u>Answer:</u> The value of $K_p$ for the equation is $2.5\times 10^3$

<u>Explanation:</u>

The given chemical reaction is:

$2HCN(g)\rightleftharpoons H_2(g)+C_2N_2(g);K_1$

The chemical equation for which the equilibrium constant is to be calculated follows:

$H_2(g)+C_2N_2(g)\rightleftharpoons 2HCN(g);K_p$

As, the equation is the result of the reverse of given reaction. So, the equilibrium constant for the equation will be the inverse of equilibrium constant for the given reaction.

The value of equilibrium constant for the equation is:

$K_p=\frac{1}{K_1}$

We are given:

$K_1=4.00\times 10^{-4}$

Putting values in above equation, we get:

$K_p=\frac{1}{4.00\times 10^{-4}}=2.5\times 10^3$

Hence, the value of $K_p$ for the equation is $2.5\times 10^3$

State one advantage of using solar energy instead of burning fossil fuels to produce thermal energy for your home

Pachacha [2.7K]

Solar energy will not run out (unless the sun burns out), but the supply of fossil fuels we use is slowly depleting. Burning fossil fuel also releases greenhouse gas into the air, which is bad for the atmosphere.
