August 22‚ 2013 Assignment 1: The Chemistry of Life Effects of Acid Rain There are many different types of negative effects acid rain has on the world. Acid rain is the mixture of wet and dry deposition from the atmosphere containing higher than normal amounts of nitric and sulfuric acids. Pollution contributes to the forming of acid rain. One of the main causes is industrial burning of coal and other fossil fuels the oxides they contain and combine with atmospheric water which forms acids.

CONCEPTS IN ORGANIC CHEMISTRY • Inductive Effect : Inductive effect is defined as permanent displacement of shared electron pair in a carbon chain towards more electronegative atom or group. Types of Inductive effect : 1.Negative Inductive Effect : (—I effect‚ Electron withdrawing effect) when an electronegative atom or group (more electro negative than hydrogen)is attached to the terminal of the carbon chain in a compound‚ the electrons are displaced in the direction of the attached

Jashandeep Gill Gammellos Chemistry Density is one of the fundamental principles of physics. Density is the reason why a plank of wood floats on water while a piece of metal several times smaller will sink. Density of an object is measured in g/cm³ or g/cc. The equation is D=M/V‚ D being the density of the object‚ M being the mass of the object‚ and V being the volume of the object. Mass is the space an object takes up. It is the amount of matter present in an object. Mass is measured using

Mastering Chemistry Chapter 1 Notes: Mixtures‚ Solutions‚ Pure Chemical Substances‚ Compounds‚ and Elements Matter can be classified into several categories. All substances are either pure chemical substances or mixtures. Mixtures can be separated into their component parts through physical means‚ whereas pure chemical substances require chemical or nuclear reactions to separate them. Pure chemical substances can be further divided into elements or compounds. Mixtures can be either heterogeneous orhomogeneous
