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.

INTRODUCTION Lactic Acid is an organic compound with the formula CH3CH (OH) COOH. Lactic is one of the types of fermentation which occur under anaerobic respiration to produce ATP without the use of oxygen. Anaerobic respiration takes place in certain prokaryotic organisms that have an Electron Transport Chain (ETC) but do not use oxygen as a final electron acceptor at the end of the chain (Campbell et all‚ 2015) different with the aerobic respiration which use oxygen to produce ATP and its final

will show a colour change. After that record the initial reading of the burette and making sure that all your burette readings must be to an appropriate precision. Titrate the contents of the conical flask by adding to it 0.100 mole dm3 hydrochloric acid from the burette. Add the solution slowly. Swire the flask gently to mix the contents at the end indicator turns as define red colour. This is the end point of the titration. Record the final burette reading in your table of result. Repeat the titration

Macrocycle shuttling process occurs either through electrochemical oxidation of the benzidine residue or protonation of the basic nitrogens on this station. Both of these methods rely on the repulsive electrostatic interactions between the positively charged axial component and the post-switching cationic nature of the benzidine station (Figure 5.4). Deuterated trifluoroacetic acid (d-TFA) was added in the solution which resulted in the protonation of

Food production A growing population brings with it a necessity to produce more food. However‚ the potential impact on the local and global environment must be considered. Part of the solution lies in careful management to reduce energy losses in food chains‚ as well as looking to new food sources. It is necessary to find a compromise between the priority of obtaining food and the priority of protecting ecosystems. The efficiency of food production can be improved by reducing the number of levels

D Biology Procedure- see attached Data and Results- see attached Theory- PH stands for the power of hydrogen. People refer to the pH scale as a tool for finding out if a substance is acidic‚ basic‚ or neutral. This scale goes from zero to fourteen. The number seven is neutral. Any number higher than seven on this scale is basic. Any number lower is acidic
