EXPERIMENT 7: PERCENTAGE OF OXYGEN IN KClO3 Introduction: In this experiment you will determine the percentage of oxygen in potassium chlorate. You will calculate the theoretical value from the chemical formula and compare your experimental value to the theoretical value. Background: When potassium chlorate (KClO3) is heated‚ it undergoes chemical decomposition. Oxygen gas (O2) is given off and potassium chloride (KCl) remains as the residue. The equation for the decomposition of potassium

------------------------------------------------- Griffith’s experiment Griffith’s experiment discovering the "transforming principle" in pneumococcus bacteria. Griffith’s experiment‚ reported in 1928 by Frederick Griffith‚[1] was one of the first experiments suggesting that bacteria are capable of transferring genetic information through a process known as transformation.[2][3] Griffith used two strains of pneumococcus (Streptococcus pneumoniae) bacteria which infect mice – a type III-S (smooth)

Design Experiment: Enzyme Inhibitors. Research question: What is the effect of adding lead nitrate solution on the activity of amylase enzyme? Aim: To test the effect of adding nitrate solution on the activity of amylase. Background Information: Inhibitors are molecules which repress or prevent another molecule from engaging in a reaction. They are substances that attach themselves onto an enzyme and reduce or prevent the enzyme’s ability to catalyse reactions. Competitive Inhibitors are inhibitors

Background research Dry ice is a frozen mixture of Carbon dioxide‚ and like many other mixtures that give off Carbon dioxide dry ice is able to fill up a balloon. Using other substances that give off Carbon dioxide along with dry ice‚ which substances would be able to give off enough Carbon dioxide to inflate a balloon. The scientist will of course be controlling many variables. The scientists independent variable will be the substances they will be using‚ which is dry ice‚ yeast

The aim of the experiment was to examine the effects of consuming lactate before and during a prolonged exercise. The data shows that the consumption of the lactate actually did work and the performance of the subject was better than the previous three experiments of dieting. This was due to the lactate that was consumed in the CytoMax. Azevedo‚ Tietz‚ Two-Feathers‚ Paull‚ and Chapman (2007) state that CytoMax contains polylactate which speeds up the delivery of substrates and is thought to help
