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 the metal or the non-metal that is

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

CHEMISTRY 1 Lab Report on Oxidation & Reduction I. Metal-Metal Ion Displacement II. Halogen Displacement Reactions INTRODUCTION A series of experiments had been conducted to determine the order of displacement strengths of the metals and halogen chosen for the experiments. A displacement reaction is a reaction in which one element(metal or non-metal) displaces another element(metal or non-metal) from its salt solution. In the displacement reaction of metals‚ the more electropositive

Materials and Method In order to complete this experiment we used a combination of electrocalorimeter (immersion heater and calorimeter)‚ power supply‚ ammeter (0 to 3 A)‚ voltmeter (30 V)‚ rheostat‚ connecting wires‚ thermometer‚ stopwatch‚ laboratory balance‚ and ice. In order to obtain the data‚ the DataStudio™ software is set up on the computer to use the temperature sensor on the apparatus to collect steadily the temperatures at specified time interval of 5-seconds.

WHAT IS METAL? A metal is a chemical element that is a good conductor of both electricity and heat. Metals are malleable and ductile and have lustrous appearance. They have moderate to high physical constants and high tensile strength. Metals are further divided into two main groups - ferrous and non ferrous metals. TYPES OF METAL • FERROUS METAL These are metals which contain iron. They may have small amounts of other metals or other elements added‚ to give the required properties
