symbol is S‚ and it’s in the Chalcogen family. Sulfur has a lot of roles to play in our bodies. It’s also one of the abundant elements in our bodies with a mass percentage of 0.2. Sulfur’s atomic number is 16‚ and its Mass number is 32.066. In addition‚ Sulfur is a non-metal. Sulfur has multiple physical and chemical properties; one of the physical properties is that Sulfur is insoluble in water. A chemical property for Sulfur is that it’s a very reactive element.

Properties of Chemical Reactions Ms. Whitty‚ Science 10 Fiona Adams‚ November 1st‚ 2012 Introduction Chemical reactions are a part of our daily lives‚ from rusting metal to making bread to leaves changing colour in the fall. A chemical reaction is the process that occurs when two or more substances combine to produce a chemical change. When a chemical reaction takes place‚ the change is indicated by one or more qualitative properties. The colour or odor could change‚ gas could be produced

impressive is their growth which is twice the overall export growth of Pakistan. Basic Chemical manufacturer may be defined as production of drugs and chemical by synthesis‚ fermentation or extraction from naturally occurring materials of biological or mineral origin. Unfortunately‚ while the pharmaceutical formulation industry has grown at a relatively rapidly pace‚ the basic chemical industry in Pakistan has lagged behind. Basic manufacturer is dependent upon a reasonably well-developed petrochemical industry

Linked List Basics By Nick Parlante Copyright © 1998-2001‚ Nick Parlante Abstract This document introduces the basic structures and techniques for building linked lists with a mixture of explanations‚ drawings‚ sample code‚ and exercises. The material is useful if you want to understand linked lists or if you want to see a realistic‚ applied example of pointer-intensive code. A separate document‚ Linked List Problems (http://cslibrary.stanford.edu/105/)‚ presents 18 practice problems covering

Chemical Composition of Natural Gas Natural gas is a naturally occurring gas mixture‚ consisting mainly of methane. While most of the gas supplied to Union Gas is from western Canada‚ some gas is supplied from other sources‚ including the United States and Ontario producers. While the gas from these sources has a similar analysis‚ it is not entirely the same. The table below outlines the typical components of natural gas on the Union Gas system and the typical ranges for these values (allowing for

Year 11 Module 1 – The Chemical Earth The Earth is made up of a large number of different substances: elements‚ compounds & mixtures We can classify elements & compounds as pure substances. These are always HOMOGENEOUS. Mixtures are not pure substances and can be either homogeneous or HETEROGENEOUS. Pure substances have a fixed composition eg copper metal‚ sulfur‚ carbon dioxide (CO2)‚ methane (CH4). Mixtures have variable composition and can also be separated into its components relatively
