Answer:

Kc = 0.402.

Explanation:

We can calculate Kc from the relation: Kc = [NOCl]² / [NO]²[Cl₂].

[NOCl] = 0.30 M, [NO] = 0.65 M, and [Cl₂] = 0.53 M.

Now, we can get Kc:

Kc = [NOCl]² / [NO]²[Cl₂] = (0.30 M)² / [(0.65 M)².(0.53 M)] = 0.402.

Aluminum metal can be recycled from scrap metal by melting the metal to evaporate impurities. a. Calculate the amount of heat ne

fenix001 [56]

The amount of heat required to purify the Al is 25.94 * 10^3 J

<h3>What is heat capacity?</h3>

The term heat capacity refers to the amount of heat required to raise the temperature of a substance by 1K. The aluminum was heated from 298 K to 933 K then it melted.

The total heat required is;

H = ncdT + nL

H = (1 * 24 * (933 - 298)) + (1 * 10.7 * 10^3)

H = 15.24 * 10^3 J + 10.7 * 10^3 J

H = 25.94 * 10^3 J
