MISSED THIS? Watch KCV: The Reaction Quotient, IWE: Predicting the Direction of a Reaction by Comparing Q and K : Read Section 16.7. You can click on the Review link to access the section in your eText. Nitrogen dioxide dimerizes according to the reaction: 2 NO$_2$ (g) $\rightleftharpoons$ N$_2$O$_4$ (g) K$_p$ = 6.7 at 298 K A 2.35-L container contains 0.023 mol of NO$_2$ and 0.096 mol of N$_2$O$_4$ at 298 K. Correct Correct answer is shown. Your answer 427 was either rounded differently or used a required for this part. Q is calculated in a manner similar to that for an equilibrium constant; however, the v rather than equilibrium values: $Q = \frac{[N_2O_4]}{[NO_2]^2}$ Note that concentrations need to be calculated from the given moles and volume and Part C Is the reaction at equilibrium? If not, in what direction will the reaction proceed? The reaction is at equilibrium. The reaction is not at equilibrium and will shift to the right. The reaction is not at equilibrium and will shift to the left. Submit Request Answer Provide Feedback

infty _(c) State the domain and range of the arccosine function. (Give your answer as an interval in the form (a,b)). Use the symbol infty for infinity, cup for combining intervals, and an appropriate type of parenthesis "(",")", "[","]" depending on whether the interval is open or closed. Enter () if the interval is empty. Express numbers in exact form. Use symbolic notation and fractions where needed.) domain: range: State the domain and range of the arccosine function.

Part A In the past 50 years, medical research has focused on the role of mitochondrial oxidative stress (MOS) as the trigger in many diseases as well as the aging process. Choose the true statement(s) about mitochondria and MOS. To be marked correct, you'll need to select all true statements, as there may be more than one correct answer. View Available Hint(s) Diseases associated with aging that may be influenced by the mitochondria include Parkinson's, cancer, atherosclerotic cardiac disease, and Type 2 Diabetes. The use of antibiotics such as penicillin has proved effective in reducing ROS in mitochondria and thus reducing damage in tissues, which may lead to physiological effects in the cell. Part A In the past 50 years, To be marked correct, you'll need View Available Hints. ative stress (MOS) as the trig and MOS one correct answer Diseases The use of antibiotics include Penicillin, cancer, atherosclerotic cardiac disease, and Type 2 Diabetes. The unique features of mitochondria that may explain the role of this organelle in disease processes and aging is the fact that it has its own DNA, mtDNA, in the form of a circular chromosome as do bacteria. The frequency of mutations in DNA may lead to physiological effects in the cell.

3. (a) A harmonic plane wave is travelling in free space in the z-direction with a frequency of 300Hz. The light is linearly polarized with the electric field oscillating along the x-axis. At time t = 0 and point z = 0 the electric field is positive at 50% of its maximum amplitude $E_0$, and decreasing. (i) Write an expression for this electric field. (ii) Write an expression for the magnetic field. (iii) How would this change if the light was circularly polarized? [3 marks] (b) Explain using a diagram the difference between coherent and incoherent light [2 marks] (c) Show that the following wavefunction satisfies the wave equation. [3 marks] (d) A beam of linearly polarized light is perpendicularly incident on an ideal polarizer. What angle would the transmission axis of the polarizer need to be set to relative to the axis of polarization to allow 30% of the light through. [2 marks]
