Question

question 12 (0.5 points) give the formula from the systematic name potassium sulfide 1 2 a. p b. p₂ c. p₃ d. k e. k₃ f. k₂ g. s h. s₂ i. s₃ j. so₃ k. so₄ l. posse

Explanation:

Step1: Identify element symbols

Potassium has symbol K, sulfur has symbol S.

Step2: Determine ion charges

Potassium forms a +1 ion ($K^+$), sulfur forms a -2 ion ($S^{2 -}$).

Step3: Balance charges

To balance charges, we need 2 potassium ions for 1 sulfur ion.

Answer:

D. K, G. S
