description on acid rain as well as a focus on acid rain in eastern Canada. This report contains a very helpful basic background on acid rain as well as a questionnaire. It involves an annual report on the Federal-Provincial Agreements‚ sulphur dioxide emissions in the seven most eastern provinces‚ trends in acid deposition in the Atlantic provinces from 1980-1994‚ as well as acid precipitation in Kejimkujik‚ Nova Scotia. It also includes data tables‚ graphs and interesting facts concerning acid rain.

TEABAG EXTRACT AS AN ALTERNATIVE FOR INK An Investigatory Project Chapters 1- 3 Submitted by: Alfonso‚ Manuela Fairbanks Garcia‚ Tonica Paga Cho‚ Jung Hun Lat‚ Manuel Miguel Feliciano November 2013 Chapter I Introduction A. Background of the Study The group will conduct the study because the group noticed that teabag extract is dark in colour and it can be use to make ink‚ and also the group noticed that teabags are made from natural resources. Some kinds

overall ions in the solution‚ hence more conductivity; since electrons are moved through ions. What I found through three attempts of finding the average conductivity of HCL is 4978.66666667 µS/cm. Which comparably to the 2 different solvents I chose‚ is the most conductive. This is because once again‚ HCL has a wide amplitude of ions and is a strong acid. Where comparing to the conductivity of distilled water to HCL would be evidently HCL. This is because distilled water doesn’t contain ions‚ hence

Abstract The activity of invertase and the quantification of albumin and casein were performed and analyzed after extraction of the said proteins from their respective sources. Isolation of proteins was initiated by the breakage of the cell wall / membranes in three different ways. Homogenization of invertase‚ albumin and casein were achieved via grinding process‚ addition of 1M acetic acid and acidification by 0.1M hydrochloric acid correspondingly. Extraction of invertase and casein involved precipitation

Lab Report Acids and Alkalis: Chemistry of Neutralization and Salt Formation Introduction: An acid is a group of chemicals. Acids are positively charged ions‚ they are liquid and are solutions of pure compounds in water. If you want to know if something is an acid‚ you can test it by using litmus paper. Acids will turn litmus paper red‚ whilst alkalis will turn it blue. Alkalis are negatively charged ions and are usually solid. Aim: To find out how much of different acids is needed to neutralize

which both prove the erythro-2‚3-dibromo-3-phenylpropanoic. Determination of the Stereochemistry of 2‚3-dibromo-3-phenylpropanoic acid. Introduction The purpose of this experiment was to determine the mechanism of the reaction of trans-cinnamic acid with the addition of bromines to 2‚3-dibromo-3-phenylpropanoic acid. An addition of bromine was added to trans-cinnamic acid and it is necessary to determine whether the intermediates were syn or anti addition or a mixture of them both to find the stereochemistry

and extracellular environment of the cell are aqueous solutions. They are primarily composed of water (the solvent)‚ and a variety of dissolved solutes‚ such as sugars‚ amino acids‚ and ions. The plasma membrane of the cell is selectively permeable‚ allowing water to freely pass through‚ but regulating the movement of solutes. Water and some dissolved solutes move via passive diffusion through the plasma membrane. Diffusion is a process where molecules move from an area of high concentration to an area
