After Fran graduated with an undergraduate art degree in 2008, she decided to combine her knowledge and love of art with a second love—plants and flowers—toward developing a business. Her intent was to focus on a specialty niche in the flower shop business. She decided to concentrate her efforts on make-to-order special flower arrangements, like are typically found at banquets and weddings. Due to her talent and dedication to doing a good job, she was highly successful, and her business...

I don't understand what calculations I would have made to create
the buffer solution from Part D of the lab. I understood the
procedures I took to create the solution but when the report asks
to show the calculations used to prepare the buffer solution I am
not sure other than mixing the volumes indicated in the procedures
section.
Thank you

Directions: Please complete Prelecture Assignment and upload answers to Carmen as a PDF before coming to lecture. Before attempting this worksheet, please read Lab 8 as this worksheet accompanies the lab and helps you get your lab notebook ready by guiding you through the necessary calculations that will be needed to start the experiment. This lab takes more thought and effort to set-up, but faster to complete if you think about things now. Please bring a copy of the completed...
Part I— Just Bad Luck? Brrrring! Brrrring! Jane checked the caller ID on her phone. “Sam! Great!” she thought. It was always nice to get a call from her older brother. But a little twinge of worry tugged at her. It was just a couple of weeks ago that he had mentioned making an appointment with his doctor about some abdominal pain he had been having. “Hi Sam! It’s great to hear from you,” Jane answered. “Hi Jane. Well I...

A. Issues [1] In addition to damages for one year's notice period, can a trial judge award significant damages for the mere fact of an employee's dismissal, or for the stigma that that dismissal brings? Or for the employer thereafter competing with the ex-employee for the clients, before the ex-employee has got a new job? B. Basic Facts [2] This is an appeal from 2009 ABQB 591 (CanLII), 473 A.R. 254. [3] Usually a judgment recites facts before law. But...
For the preparation and standardization of NaOH with KHP im supposed to boil water for 1hr and 30 min to remove CO2....the problem is that if I don't boil it for that long and (30 min) b/c of not enough time but I put the water I boiled for 1/2 hr aproximately into a NaOH bottle with a CO2 absorber and stored it there for a few days. I would assume that I would have to boil the water again...but...
