________________________ Internal Assessment Criteria Aspect 1 Aspect 2 Aspect 3 Total DCP CE Aim: The aim of this practical is to plot and investigate the pH titration curves for the titration of a strong acid with a strong base and of a weak acid with a strong base‚ and find Ka of the weak acid. Procedure: Part I 1. Pour 30 ml of the HCl solution of unknown concentration in a 100 ml beaker. 2. Add a stirring magnet. 3. Place the beaker on the magnetic heater and activate the rotating motor but not

The quote above illustrates how Foucault claimed that being aware of constant surveillance created a sense of self-governance. Even tough there was not any set laws due to the fear Big Brother installed‚ the citizens of Oceania lived very precautious‚ uncertain of when or how they would break the law. Winston was constantly blocking out any thoughts not regarding big brother. The constant surveillance consequently created a sense of always policing themselves. Winston made sure he maintained a good

the effect of music and age on STM (WM). The results of the experiment were confirming the hypothesis to some extent. The hypothesis was that the older the subject conducting the experiment is‚ the higher the cognitive performance‚ which will result in a higher level in completing the task. Also the subjects will be distracted when the music is played. However‚ some of the results did not match the hypothesis; such as Group2 (Year 9 Newman) that completed the task and reached a higher level with the

First Year Seminar Psychology 190-01 In Jonathan Haidt’s book‚ The Happiness Hypothesis‚ Haidt explains genuine examples to get many familiar points across to the audience without us people knowing what he is trying to do. All we are doing is reading the book trying to understand what Haidt is trying to tell us through his style and tone of each different chapter. To begin‚ chapter four of The Happiness Hypothesis‚ in my opinion was very interesting. This chapter is the chapter that has kept

1.) Were the North American megafauna wiped out by early human colonizers? The Overkill hypothesis is of the Clovis crossing into a “virgin continent” (The America’s) and wiped out the megafauna due to overhunting. First developed by Paul Martin in the 1960’s‚ Clovis started to occupy North and South America 13‚500-12‚500 years ago; soon after early sites were established 17 genera of North and South American megafauna went extinct between 13‚250-12‚900 (other species such as ground sloths become

If I only dissociate to the extent of 1.50%‚ what is the value of my Ka? 3. I am a 0.20 M solution of hydrocyanic acid‚ HCN‚ with a Ka of 4.93 x 10¯ 10 . What is my pH? 4. I am a buffer made from 0.10 M acetic acid and 0.15 M sodium acetate. If the Ka for acetic acid is 1.77 x 10¯ 5 ‚ what is my pH? 5. I am

RECRYSTALLIZATION AND MELTING POINT DETERMINATION OF BENZOIC ACID ANSWERS TO QUESTIONS 1. How does the use of fluted filter paper hasten filtration? Why is it advisable to place a small piece of wire between the funnel and the mouth of the flask during hot filtration? Fluted filter paper is effective in preventing crystal formation in the filter paper. It is also often used in filtering hot saturated solution used during crystallization. One major advantage of a fluted filter is that it increases

Since I was young‚ I have striven to achieve my goals; I call it a "determination to succeed." Without a "determination to succeed‚" giving up in life‚ when a situation seems impossible to overcome‚ becomes second nature. The methods one uses to overcome the challenges faced in life affects how one acquires success. For example‚ my ancestors did not overcome their struggle for equality without self-determination to better their lives. Thus‚ their lives have been an inspiration for me. The motivation
