<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

Why is sugar soluble in water while oil cannot form a solution?​
Viefleur [7K]

Answer:

the water and alcohol interact, which means the water doesn't even dissolve the sugar or color as well as it normally would. Oil molecules are not polar so they cannot dissolve either the coloring or the sugar.

TRUE or FALSE: The charge of an atom (ion) is determined by the ratio of electrons to protons.
Damm [24]
True The positive electric charge of a proton is equal in magnitude to the negative charge of an electron; therefore, the net electric charge of an ion is equal to its number of protons minus its number of electrons. Ions are highly reactive species.
