EXPERIMENT 1 DETERMINATION OF ASCORBIC ACID CONTENT IN VITAMIN C TABLETS INTRODUCTION To calculate the mass of the ascorbic acid and hence the mass percentage of ascorbic acid in the vitamin C tablet. PROCEDURES (Refer to Lab Manual) 1. Accurately weight vitamin C (effervescent type) in a 50 ml beaker. Add about 30 ml of deionised water to dissolve the vitamin C tablet. Once the tablet has dissolved completely‚ transfer the solution into a 250 ml volumetric flask via a plastic filter

"K-I-S-S" redirects here. For other uses‚ see Kiss (disambiguation). KISS is an acronym for "Keep it simple‚ stupid" as a design principle noted by the U.S. Navy in 1960.[1][2] The KISS principle states that most systems work best if they are kept simple rather than made complex; therefore simplicityshould be a key goal in design and unnecessary complexity should be avoided. The phrase has been associated with aircraft engineer Kelly Johnson (1910–1990).[3] The term "KISS principle" was in popular

This is famous Petersburg paradox‚ according to which a player’s expectation is infinite (does not exist) if he is to receive 2x dollars when‚ in a series of flips of a balanced coin‚ the first head appears on the xth flip. 17.

1) 0.069 mol MgSO4/ 0.015 mol H2O = 4.6 = 5 Formulae for hydrated MgSO4 = MgSO4 5H2O 2) There are at least two reasons why heating to find percentage of water in hydrated crystals is not recommended for all hydrates. The first reason is that some hydrates have such a strong bond with the water that not all of it will be able to be removed. The second reason is that different hydrates have their own mass. Depending on the mass and type of hydrate‚ some of the molecule may be burned off from heating

24‚ March 2013 Moral Dilema Determination inspired many of the suffering persevere in their rescue efforts which eventually paid off when they escaped. Each person must make difficult judgment in the course of everyday life. Decisions that seem trivia at the time‚ sometimes the choice is better to meet the expectations of others or to meet the expectation of the conscience like in “alive”‚“Thirty eight who so murder didn’t call the police”and “shooting an elephant”

Macroeconomics 2 - Essay 1 Explain for which reasons the real wage is expected to be acyclical in the Classical model‚ countercyclical in the Keynesian model and procyclical in the New Keynesian model. Which model would better fit the empirical evidence? Real Wage is defined as the payment to labour measured in units of output adjusted for the current level of inflation. This can be written as: Real Wage= Nominal Wage x (Expected Price Level/ Price Level) W/P = ω x X /P P Real Wage cyclicality

Lab #5: Refraction of Light Theory: Refraction can be defined as the bending of a wave when it enters a medium which causes it to have some reduced speed. In terms of light‚ refraction occurs when the ray passes through some medium which slows its speed; such as water or glass. In this instance the ray tends to bend towards the normal of the medium. The amount of bending or refraction which occurs can be calculated using Snell’s Law (). Objective: To measure the index of refraction of Lucite

Patient Self-Determination Act HCR/210 September 24‚ 2010 Vivian Rice Patient Self-Determination Act The effect of the Patient Self-Determination Act on health care delivery is that it gives the patient the chance to choose how or if they will be kept alive in case of terminal illness or during a risky procedure. The patient will put in writing how they want to be kept alive and what measures to use to keep them alive in the case there is not a “reasonable hope of recovery” (Thomson Delmar
