Q:

Which pair of atoms has the highest electronegativity difference?

 

(Calcium's electronegativity is 1.0

Fluorine's electronegativity is 4.0

Hydrogen's electronegativity is 2.2

Sodium's electronegativity is 0.93)

A) F-F B) Ca-F
C) H-F D) Na-F
 
Answer & Explanation Answer: D) Na-F

Explanation:

F-F = 4 - 4 = 0

Ca-F = 4 - 1 = 3.0

H-F = 4 - 2.2 = 1.8

Na-F = 4 - 0.93 = 3.07

 

Hence, the highest electronegativity difference is in Na-F.

Q:

Mg+O2=MgO

Balance the above Chemical equation?

A) 2Mg + O2 ----> 2MgO B) 2Mg + O ----> 2MgO
C) 2Mg + O ----> MgO2 D) 2Mg + O2 ----> MgO2
 
Answer & Explanation Answer: A) 2Mg + O2 ----> 2MgO

Explanation:

Given Equation is 

Mg + O2 → MgO

Balancing the Chemical Equation is nothing but Conservation of Matter. As Matter is Neither created nor Destroyed, it must be conserved.

Here we have 1 Mg and 2 O on the left side and 1 Mg and 1 O on the right side

To balance that, add 1 Mg on the left side so that it becomes 2 Mg and 2 O on the left side

i.e,

2 Mg + O2 → 2 MgO

Here it has 2 Mg & 2 O on the left side and 2 Mg and 2 O on the right side and the Chemical equation is Balanced.
