Concept explainers
(a)
Interpretation:
The unit of pressure 0.745 atm should be converted to mmHg.
Concept Introduction:
The pressure which is exerted by the weight of the air above it at any point on the surface of earth is known as atmospheric pressure. The atmosphere supports a mercury column about 760 mmHg at sea level.
A conversion factor is a numerical ratio which is used to show a measurement in one unit as another unit. It is always equal to 1.
(b)
Interpretation:
The unit of pressure 992 torr should be converted to bar.
Concept Introduction:
The pressure which is exerted by the weight of the air above it at any point on the surface of earth is known as atmospheric pressure. The atmosphere supports a mercury column about 760 mmHg at sea level.
A conversion factor is a numerical ratio which is used to show a measurement in one unit as another unit. It is always equal to 1.
(c)
Interpretation:
The unit of pressure 365 kPa should be converted to atm.
Concept Introduction:
The pressure which is exerted by the weight of the air above it at any point on the surface of earth is known as atmospheric pressure. The atmosphere supports a mercury column about 760 mmHg at sea level.
A conversion factor is a numerical ratio which is used to show a measurement in one unit as another unit. It is always equal to 1.
(d)
Interpretation:
The unit of pressure 804 mmHg should be converted to kPa.

The maximum level that the EPA considers safe for lead air pollution is 1.5 μg/m³ Part A If your lungs were filled with air containing this level of lead, how many lead atoms would be in your lungs? (Assume a total lung volume of 5.40 L.) ΜΕ ΑΣΦ = 2.35 1013 ? atoms ! Check your rounding. Your final answer should be rounded to 2 significant figures in the last step. No credit lost.

For each reaction in the assignment, you must write each mechanism three times (there are 10 reactions, so 30 mechanisms). (A) do the work on a tablet and save as a pdf., it is expected to write each mechanism out and NOT copy and paste the mechanism after writing it just once. Everything should be drawn out stepwise and every bond that is formed and broken in the process of the reaction, and is expected to see all relevant lone pair electrons and curved arrows.arrow_forward
