For the same mixture, under the same conditions described in problem 7, calculate keq for 2nh3 (g) n2 (g) + 3h2(g). how is the k

nekit [7.7K]

<u>Answer:</u> The relation between the forward and reverse reaction is $K_f=\frac{1}{K_r}$

<u>Explanation:</u>

For the given chemical equation:

$2NH_3(g)\rightleftharpoons N_2 (g)+3H_2(g)$

The expression of equilibrium constant for above equation follows:

$K_f=\frac{[N_2][H_2]^3}{[NH_3]^2}$ .......(1)

The reverse equation follows:

$N_2 (g)+3H_2(g)\rightleftharpoons 2NH_3(g)$

The expression of equilibrium constant for above equation follows:

$K_r=\frac{[NH_3]^2}{[N_2][H_2]^3}$ .......(2)

Relation expression 1 and expression 2, we get:

$K_f=\frac{1}{K_r}$

Hence, the relation between the forward and reverse reaction is $K_f=\frac{1}{K_r}$

Based on the electron configuration of the two atoms, predict the ratio of metal cationic (+) atom to nonmetal anionic (-) atom

Pepsi [2]

The metal cationic (+) atom to nonmetal anionic (-) atom ratio in the compound formed between Potassium and Chlorine is 1:1.

<h3>What is a compound?</h3>

A compound is made up of two or more atoms that are chemically combined together. In this case, we have the atoms; Potassium and Chlorine.

The electronic configuration of the atoms is not shown here but the metal cationic (+) atom to nonmetal anionic (-) atom ratio in the compound formed between Potassium and Chlorine is 1:1.

Which forces of attraction do you think are stronger, the attractions that are broken or the new attractions that are formed? Ex

jasenka [17]

Answer: The forces of attraction are stronger in new attractions that are formed.

Explanation:

When a chemical reaction takes place between two or more different compounds then less reactive substance is displaced by the more reactive substance.

During this process, when bonds are broken between the reactants then it means the force of attraction is less stronger. The formation of new compounds occur because force of attraction is more in these new substances due to which its atoms come closer to each other.

Thus, we can conclude that forces of attraction are stronger in new attractions that are formed.

How many grams of nacl are in 250 g of a 15.0% (by weight) solution?

Gelneren [198K]

Answer: -

37.5 g of NaCl are in 250 g of a 15.0% (by weight) solution.

Explanation: -

Total mass = 250 g

Percentage of NaCl = 15.0 %

= $\frac{Number of grams of NaCl present}{total mass}$
