permanganate (KMnO4) and oxalic acid (H2C2O4)‚ three determinations were performed‚ each with different initial concentrations of the reactants. Each initial concentration resulted in a unique reaction rate; these rates were then examined using the method of initial rates to determine the order of the reaction with respect to both KMnO4 and H2C2O4. The rate constant (k)‚ was then calculated‚ and the rate equation for the reaction written1. In part two; determinations were done at varying temperatures while keeping

Introduction: Recognition of self-determination in international law is new. International law has adopted self-determination as a right in 1941 by UN charter‚ but from the beginning of the civilization the desire for self-determination was there. Debate over this topic is like never ending saga‚ as it’s related to government‚ peace‚ war‚ right

Experiment V02 An analysis of aspirin tablets Procedure a. Weigh accurately a definite number of aspirin tablets (two or three tablets weighing no more than 1.5 g) into a 250 cm3 conical flask. Initiate the hydrolysis of the aspirin by adding 25 cm3 of 1.0 M sodium hydroxide by pipette‚ diluting with approximately the same volume of distilled water. Warm the flask over a tripod and gauze for ten minutes to complete the hydrolysis. b. Cool the reaction mixture and transfer with washings to

Objective To determine soluble solid concentration in some fruits including tropical and temperate fruits by using handheld refractometer. Introduction “Sugar are the major soluble in fruits juices and estimate of sweetness. Other soluble materials include organic and amino acids‚ soluble pectins‚ and others. Soluble solid concentration can be determined in a small sample of fruits juice using a hand held refractometer. The measurement must be made at 20°C to get an accurate value. This instrument

Exercise psychology and Self-Determination Theory Exercise psychology is defined as the study of psychological factors underlying participation and adherence in physical activity programs (Anshel‚ 1948). Health and exercise psychology have gained much prominence over the last few decades especially when it comes to explaining and understanding exercise behaviours (Berger‚ Pargman‚ & Weinberg‚ 2007).The advancement of technology has made life easier resulting in more physically inactivity both

Henri Murphy Mr. Dietrich English 101 29 Aug 2014 Determination I have been in school for twelve years and seen many friends drop out. I’ve never understood how they could make it so far and just give up. But the only thing that seems to make any since is a lack of determination. It is very good to have vivid image of the things you want in life. A lion doesn’t hunt its prey with its eyes closed so don’t blindly chase after a dream or hope to accomplish something without putting any effort
