Aim: The rate at which a reaction occurs‚ or takes place‚ is affected by various factors‚ such as the temperature at which the experiment is conducted in‚ the pressure which is given‚ the surface area which is exposed‚ use of catalysts‚ and the concentration. In this investigation‚ I would be investigating the affect of surface area‚ or particle size‚ in the rate at which a reaction occurs. Background Information: The more finely divided the solid is‚ the faster the reaction happens. A powdered

JOULE’S LAW Introduction and research question In this experiment‚ we were going to investigate the resistance R of an immersion heater. We had to make our own heater‚ and measure the resistance using a multimeter. Then we had to measure the current I‚ using an ammeter and a voltmeter. And at last‚ we had to determine the power P of the immersion heater. This experiment would require to make a table with the data collection‚ a graph‚ and a few calculations using Joule’s and Ohms law. Our research

To Investigate the Effect of Varying pH on the Rate of a Reaction Catalysed by Trypsin Aims I hope to determine the effect of varying pH on the rate of reaction catalysed/controlled by the enzyme trypsin. Method 1. Add 4cm³ of the 2% trypsin solution in to 6 test tubes labelled A-F 2. Add 4cm³ of the appropriate buffer solution to each. ( I will be testing pH 4‚5‚7‚8‚8.8 and 10) 3. Add 4cm³ of distilled water and 4cm³ of the appropriate buffer solution to 6 control test tubes labelled CA-CF to see

USE OF ONION ROOT TIPS FOR MITOTIC DIVISION OBSERVATIONS Introduction The zone of cell division on the onion root tip is a great place to observe mitotic cell divisions. Through the observation and comparison of different regions of the root tip‚ the duration of mitotic stages and mitotic indexes are determined for the various divisions of the root tip. Methods Each group used a compound microscope to analyze the different sections of the onion root tip. The root tip was visually

An Ethical and Practical Defense of Affirmative Action Affirmative action has been the subject of increasing debate and tension in American society. However‚ the debate over affirmative action has become ensnared in rhetoric that pits equality of opportunity against the equality of results.
