Question Solved1 Answer just last question! One pathway for the destruction of ozone in the upper atmosphere is O3(g) + NO(g) -> NO2(g) + O2(g) Slow NO2(g) + O(g) -> NO(g) + O2(g) Fast Overall reaction: O3(g) + O(g) -> 2O2(g) Identify the correct term to describe each of the following species. Catalyst: nitrogen monoxide Product: molecular (di)oxygen Intermediate: NO2(g) Reactant: O3(g) Reactant: O(g) 1 pts You are correct. Previous Tries Ea is 14.0 kJ/mol, for the uncatalyzed reaction: O3(g) + O(g) -> 2O2(g) Ea for the same reaction, when catalyzed as above, is 11.9 kJ/mol. At -44°C, what is the ratio of the rate constant for the catalyzed reaction to that for the uncatalyzed reaction? (Assume the frequency factor A is the same for each reaction.) ans:3.01 One of the concerns about the use of freons is that they will migrate to the upper atmosphere, where chlorine atoms can be generated by the reaction CCl2F2 -> CF2Cl + Cl (photolysis of Freon-12) Chlorine atoms can also act as a catalyst for the destruction of ozone. The activation energy for the reaction Cl + O3 -> ClO + O2 is 2.1 kJ/mol. Cl is regenerated by the fast reaction ClO + O -> O2 + Cl If the frequency factors are the same and both catalysts are in equal concentration, how many times faster, at -52°C, does the Cl catalysed reaction proceed compared to the reaction catalysed as described in the previous question.

KMnO4+KNO2+H2SO4----->MnSO4+H2O+KNO3+K2SO4identify the atom oxidized, the atom reduced, balance the equation and write the net ionic equation

A vector is 27.0 m long and makes an angle of 60.0° counterclockwise from the y-axis (on the side of the -x-axis). What is the x-component of this vector? im

Consider the rectangle in the (𝑥,𝑦) plane with vertices (𝑎,𝑏), (𝑎+ℎ,𝑏), (𝑎,𝑏+𝑘), and (𝑎+ℎ,𝑏+𝑘), where ℎ > 0 and 𝑘 > 0. Show, by direct calculation of the line integral from the definition, that the counterclockwise integral of around the rectangle is 0 if the origin is outside the rectangle and 2𝜋 if it is inside. F= = (-y, x2 + y2

Scenario You work for a small company that exports artisan chocolate. Although you measure your products in kilograms, you often get orders in both pounds and ounces. You have decided that rather than have to look up conversions all the time, you could use Python code to take inputs to make conversions between the different units of measurement. You will write three blocks of code. The first will convert kilograms to pounds and ounces. The second will convert pounds to kilograms and ounces. The third will convert ounces to kilograms and pounds. The conversions are as follows: . 1 kilogram = 35.274 ounces • 1 kilogram = 2.20462 pounds • 1 pound = 0.453592 kilograms • 1 pound = 16 ounces • 1 ounce = 0.0283 kilograms • 1 ounce = 0.0625 pounds For the purposes of this activity the template for a function has been provided. You have not yet covered functions in the course, but they are a way of reusing code. Like a Python script, a function can have zero or more parameters. In the code window you will see three functions defined as def convert_kg(value): , def convert_pounds(value): , and def convert_ounces(value): . Each function will have a block showing you where to place your code. What you need to do Best Practices to Follow: Within the functions you will see a line telling you where to write the code. 1. Writing detailed comments and docstrings. 2. Organizing and structuring code for readability. 3. It is recommended that you use your own test cases in order to check for correctness. You can test your code inside the _main__ provided. Steps for Completion Tasks Write code for the convert_kg(value) function that converts value into pounds and ounces. The function should output the following statement "x kg converted is y pounds and z ounces.". Write code for the convert_pounds(value) function that converts value into kg and ounces. The function should output the following statement "x pounds converted is y kg and z ounces.". Write code for the convert_ounces (value) function that converts value into kg and pounds. The function should output the following statement "x ounces converted is y kg and z pounds.". Make it your own The company has extended its product range to include top-of-the-range sparkling beverages that can also be bought wholesale. Extend your code to include conversions for liquid measurements such as fluid Ounces, litres, pints, and quarts. Task This task will be manually graded by your instructor to check that the goals and the requirements for the task have been met.

Problem 2: Recall that f (y) = 2 - exp(-2y) for y > 0. Given Y = y, a discrete random variable, N, has conditional distribution fNlY (nly) .exp(-y) valid for integer n > 0. 1. Derive a conditional density, FYN (y|n) and identify it. 2. Determine conditional expectation and variance for (Y N = 9), that is: E [YN =9] and Var Y N =9]

Eleven employees were put under the care of the company nurse because of high cholesterol readings. The nurse lectured them on the dangers of this condition and put them on a new diet. You have the cholesterol readings of the 11 employees both before the new diet and one month after use of the diet began. (1). Given alpha = 0.01, the average of differences
