Discussion Questions 1. Why do different metals have different characteristic flame test colours? The photons emitted during the test precisely match the quantum energy difference between the excited state and the ground state. For different elements the spacing between the ground state and the higher energy levels is different. So different elements have different flame test colours. 2. Most salts contain a metal and a non-metal. Look at the compounds we tested and determine whether it is

experiences is defined as personality (Cloninger‚ 2007). By observing one’s behaviour casually‚ inferences about his personality cannot be made. An assessment of personality can only be determined from the results generated from a series of special tests that have been designed to identify particular personality characteristics (Martin‚ Carlson & Buskist‚ 2010). Assessing Children’s personality Studies have shown that most individuals are involved in various personality assessments all throughout

Friedman Test for a random Block Design -The Friedman Test is used when compairing more than two populations or treatments randomly assigned within blocks. This is the counterpart of the F test or ANOVA used in parametric statistics. Unlike the F test or ANOVA which is used with the assumption that the observations taken from each of the populations are normally distributed‚ the Friedman test is used when no distrubutional assumptions are necessary. The following are the steps in doing the Friedman

scientific study. In statistics‚ a result is called statistically significant if it has been predicted as unlikely to have occurred by chance alone‚ according to pre-determined threshold probability‚ the significance level. Statistical hypothesis tests define a procedure that controls (fixes) the probability of incorrectly deciding that a default position (null hypothesis) is incorrect based on how likely it would be for a set of observations to occur if the null hypothesis were true. The null hypothesis

Test for the Presence of Macromolecules Introduction In this experiment‚ we are trying to identify the presence of macromolecules in certain solutions. As in our daily lives‚ macromolecules are the essential nutrients that we have to take every day‚ therefore we would like to identify the types of macromolecules that contain in some of the food or solution in order to maintain a healthy life. There are four groups of macromolecules which are carbohydrates‚ lipids‚ proteins and

Title: Flame Test Aim: To determine the cation in each of the unknown substance X‚ Y and Z by observing the flame colour of different metal compounds. Introduction: A distinctive feature of many s-block metals is their ability to produce flame colours. At temperature of a Bunsen flame‚ a compound will decompose to give gaseous atoms of its constituent elements. When an electron in the gaseous atom absorbs energy from the flame‚ it will move from an orbital with lower energy to
