A mass of 5 kg of saturated liquid vapor mixture of water is contained in a piston cylinder device at 100 kPa, initially 2 kg of water is in the liquid phase and the rest is in the vapor phase.Heat is now transferred to the water and the piston which is resting on a set of stops, starts moving when the pressure in side reaches 200 kPa, heat transfer continues until the total volume increases by 20%, determine a. the initial and final temperature b. the mass of liquid water when the piston first starts moving c. the work done during the process d. show the process in P-V diagram

The solubility rules that you might have memorized in first semester Gen Chem can have some surprising exceptions. For instance, "all" potassium salts are soluble, and "all" perchlorate salts are soluble, so we would expect potassium perchlorate (KClO4) to be a very soluble salt. But it's not! It is only slightly soluble, with a Ksp value of 1.05 X 10-2. If 5.0 g of potassium perchlorate are added to 100. mL of a 0.10 M solution of sodium perchlorate (a very soluble salt), what is the concentration of potassium ions once equilibrium has been reached?

Let X equal the number of bad records in each 100 feet of a used computer tape. Assume that X has a Poisson distribution with mean 2. Let W denote the number of feet before for the first bad record is found. Let Z denote the number of feet before for the second bad record is found. Let Y be the number of bad records in 50 feet.
(a) What is P(2 ≤ Y ≤ 4) ?
(b) What is the p.d.f. of W ?
(c) What is the p.d.f. of X ?
(d) Find P(W ≤ 50).
(e) Find P(50 ≤ Z ≤ 150).

Topic background: First reported to the World Health Organisation as an unknown virus in late December 2019, coronavirus/COVID19 developments throughout 2020 are causing great uncertainty for the global economy. This uncertainty is creating risks that entities may not have encountered before, and gives rise to new and rapidly changing conditions that auditors may not have previously encountered. Required: Conduct research on the impact of coronavirus/COVID19 on external financial report audits, then answer the following questions:
5. What are the obligations of the auditor under section 311 of the Corporations Act 2001 in relation to solvency and going concern? (100 words).

You decide to dilute a broth culture by making a series of four 1:100 dilutions. You then pipet 1 ml of the final dilution onto one agar plate and 0.1 ml onto a second plate. After incubating overnight, you count 350 colonies on the first plate (with 1 ml) and 56 colonies on the second plate (with 0.1 ml). Which plate would you use for your calculations? Why? Calculate the concentration of the original culture and be sure to include the proper units in your answer. (Hint: Draw a diagram of the dilution series to help you get the answer.)

Jamie has been accepted to a university in a city far from her home. She will need to rent an apartment and has two choices. The first choice , cost $1,000 per month, and is within walking distance of the university. The second apartment costs $925 per month, but Jamie will have to buy a bus pass in order to get to the university. The pass costs $100 per month. Jamie has been hired to work part time at a job that is a bus ride away from both apartments.
Identify which costs are relevant in the incremental analysis. What other factors should be considered?

A company had stock outstanding as follows during each of its first three years of operations: 1,000 shares of 7%, $100 par, cumulative preferred stock and 51,000 shares of $10 par common stock. The amounts distributed as dividends are presented below. Determine the total and per-share dividends for each class of stock for each year by completing the schedule. Round dividends per share to the nearest cent. Enter "0" if no dividends are paid.
