Evaluate: (5x + 4y) / 2, which is an expression of a certain experimental procedure. lf x represents the valence of Argon and y represents the summation or valencies of sulphur and Neon

Answer: 48

Explanation:

Given the expression (5x + 4y) / 2

Where x represents the valence of Argon and y represents the summation or valencies of sulphur and Neon

A neutral Argon, Sulphur and Neon will have:

The valence of Argon = 8

The valence of sulphur = 6

The valence of Neon = 8

Therefore, X = 8 and Y = 6 + 8 = 14

Substitute x and y into the expression.

(5x + 4y) / 2 = (5*8 + 4*14) / 2

(40 + 56) / 2 = 96/2 = 48

Evaluating: (5x + 4y) / 2 = 48
