Question

question 6 (5 points) retake question which of the following is electrostatically out of balance? naf k2cl fes mgo zns

Explanation:

Step1: Determine ion - charges

Sodium (Na) has a +1 charge, Fluoride (F) has a - 1 charge. In NaF, the charges balance as +1+( - 1)=0.

Step2: Analyze K2Cl

Potassium (K) has a +1 charge and Chloride (Cl) has a - 1 charge. In K2Cl, the total positive charge from two K+ ions is +2 and the negative charge from one Cl - ion is - 1. The net charge is +2+( - 1)=+1, so it is electrostatically out - of - balance.

Step3: Check FeS

Iron (Fe) can have +2 or +3 charges in common compounds. In FeS, assuming Fe in +2 state (as S has a - 2 charge), the charges balance: +2+( - 2)=0.

Step4: Examine MgO

Magnesium (Mg) has a +2 charge and Oxygen (O) has a - 2 charge. In MgO, +2+( - 2)=0, so it is balanced.

Step5: Analyze ZnS

Zinc (Zn) has a +2 charge and Sulfur (S) has a - 2 charge. In ZnS, +2+( - 2)=0, so it is balanced.

Answer:

K2Cl
