Discuss the relationship between the production of nitrogen
oxide species and the formation of ‘acid rain’ and the role played
by carbon monoxide, methane, and the hydroxyl radical.
Question 7
Acid rain is an environmental challenge in many places around
the world. It refers to rain or any other form of precipitation
that is unusually acidic, i.e. rainwater having elevated levels of
hydrogen ions (low pH). The measure of pH is a measure of the
acidity or basicity of a solution and has a scale ranging from 0 to
14. Distilled water, with carbon dioxide removed, has a neutral pH
level of 7. Liquids with a pH less...
Sketch a graph for a titration of a weak acid (burette) against
25cm^3 of a strong base (conical flask). Assume that both have
concentrations of 0.5M. Label Axes.

Question:
Researchers studying acid rain measured the acidity of
precipitation in a Colorado Wilderness area for 150 consecutive
weeks. Acidity is measured by pH. Lower pH values show higher
acidity. The acid rain researchers observed a straight-line pattern
over time. They reported that the least-squares regression line: pH
= 5.3 - (.0053 * weeks) fit the data well.
A. According to the regression line, what was the pH at the
beginning of the...
3. Answer
ALL parts of this question.
(a) Explain how greenhouse effect raises the temperature of the
troposphere.
(5 marks)
(b) N2O is a greenhouse gas. Draw the IR active
vibrations of N2O. The frequency of the bending
vibration is 596 cm-1, calculate the wavelength of light
that N2O can absorb due to this vibration (show your
working).
(c) Discuss what is meant by the term “global dimming”.
(2 marks)
(d) Explain why chlorofluorocarbons make a significant
contribution to...
Sketch a graph for a titraton of a weak acid(burette) against
25cm^3 of strong base (conical flask). Assume that both have a
concentration of 0.5M. Label axis please!
This is a 3 part question but one question
(A) Discuss the probability of landing on heads if you flipped a
coin 10 times?
(B) What is the probability the coin will land on heads on each
of the 10 coin flips
(C) Apply this same binomial experiment to a different
real-world situation. Describe a situation involving
probability.
Question 3
In order for blood to flow from the veins back into the heart,
the pressure in the right atrium must be lower than the pressure in
the veins. Two physiological pumps help increase pressure in the
venous system.
How do pressure differentials that allows for inflation and
deflation of the lungs also assist in venous return?
Explain why individuals experience edema in their lower
extremities during the course of a long distance flight.
