Explanation

Common Ion Effect – NaCl releases Cl⁻ ions, which do not react with H₂S but increase the ionic strength of the solution, reducing H₂S solubility.

Salting-Out Effect – High salt concentration decreases the solubility of gases like H₂S in water by reducing water’s ability to dissolve nonpolar molecules.

Explanation

Given the equation: 8x - 3y = 24

Substitute y = 0:

8x - 3(0) = 24 → 8x = 24

Solve for x:

x = 24 ÷ 8 = 3

Explanation

To solve for x:

x/2 + 1 = 15

Subtract 1 from both sides:

x/2 = 14

Multiply both sides by 2:

x = 28

Explanation

Substitute the given values:

a = 1, b = 0, c = -1

Now, evaluate the expression:

(a - c) - (a + b) + ab

= (1 - (-1)) - (1 + 0) + 1(0)

= (1 + 1) - 1 + 0

= 2 - 1

= 1
