Answer:
Electronic configuration of nitrogen: K=2 L=5
Electronic configuration of phosphorus : K = 2 L = 8 M = 5
The element nitrogen will be more electronegative because of the smaller size of its atom. nitrogen accepts electrons more easily.
Explanation:
The molarity of KCl solution made by diluting 75.0 ml of a 0.200M solution to a final volume of 100ml is calculated using the below formula
M1V1=M2V2
M1=0.200 M
V1= 75.0 Ml
V2= 100 ml
M2=?
by making M2 the formula of the subject M2 =M1V1/V2
=75.0 ml x0.200 M/100 Ml = 0.15 M
Answer:
One.
