Chemistry Practical: Activity Series of Metals Introduction: The chemical activity of a metal is directly related to its practical use. In this investigation you will investigate the chemical activity of metals with oxygen‚ water‚ acid and alkali‚ to rank metals in order of their activity. Aim: To observe the reactivity of metals in order to determine the activity series of metals. Risk Assessment: In this investigation‚ hydrochloric acid solution is used which is toxic by all routes of

Heavy metal contamination occurs though all facets of life such as air‚ water‚ food‚ soil‚ and in everyday objects and occurrences. When heavy metals enter the air from factories emissions and smoke‚ it is exposed to the body‚ which mostly affect your skin and lungs such as Cadmium and Arsenic. Common water contaminates are Chromium and Thallium‚ Chromium can enter the water source usually through spills and leaks from power plants. Thallium like other metals occurs naturally in water but some areas

WRITING CENTRE Harvard Referencing Guide There are many different Author-Date referencing styles (see the Referencing Comparison Sheet for one other). This guide is based on the Style manual for authors‚ editors and printers. Harvard referencing style uses references in two places in a piece of writing: in the text and in a reference list at the end. In general‚ each name that appears in the text must also appear in the reference list‚ and every work in the reference list must also be referred

is made from hardened steel with sharp points at each end. Lines drawn with a scribe are far more accurate than a line drawn with a pencil or pen. A scriber is used to make sharp‚ clearly defined lines on metal. An Engineers Square consists of a metal blade set at 90 degrees to a solid metal block (the stock). Practical uses of an engineer square is a guide for a scriber when marking out lines at right-angles to the edge of the work and a guide to setting up or checking work to see if it’s squared

without metal. The metals we use in our houses are mostly for keeping them sturdy. Though there is one problem we have when it comes to metals. That problem is that they rust. Metals rust when they are in contact with oxygen‚ and water. They rust much faster when they are in contact with salt water‚ and acid rain. We chose to see what would happen to various metals when they contacted with salt water. When the electrons move around in the salt water‚ it causes the metals to rust. The metals we chose

Density of Metals Lab 1. Purpose The purpose of this lab was answered in 4 questions‚ and their answers are here shown. The density of the metals we used were 5g/cm3. The density of a metal piece does not depend on its size‚ it depends on the total mass and total volume. The most accurate way of determining density is dividing mass by volume. You can’t identify metals by their density. It can help you narrow the options down‚ but you can’t identify a metal by using only its density. 2. Question

Metal detectors in schools pose more of a threat than a sense of security. Every student carries metal of some form on them. Pens‚ pencils‚ notebooks and other school supplies all contain metals. If we try to make schools “safer” by placing metal detectors in the entrance and exit of every school building.
