5. You have been asked to monitor the daily fluctuations in atmospheric ozone in the downtown
area of a city to determine if there is relationship
between daily traffic patterns and ozone levels. (a)
Which of the following sampling plan will you use:
random, systematic, judgmental, systematic–
judgmental, or stratified? (b) Do you plan to collect
and analyze a series of grab samples, or will you
form a single composite sample? (c) Will your
answers to these questions change if your goal is to
determine if the average daily ozone level exceeds a
threshold value? If your answer is yes, then what is
your new sampling strategy?

under a microscope, cancer cells may look very different from normal cells. they often have different sizes and some may be larger than normal while others are smaller. cancer cells are often abnormally shaped and the control centre of the cell (the nucleus) may have an abnormal appearance.

i think? ?

elements make up everything, and they combine to make compounds.

the answer is c

a electronegativity decreases beacuse the size of nucleus is bigger.

the dissociation of nickel hydroxide is follows:

the concentration of hydroxide ion is

the equilibrium constant value of nickel hydroxide is = 6.1 * 10^-^1^6 and thus equilibrium equation can be written as:

thus, concentration of ni is 0.23 * 10^-^4 mol /l
