When looking out onto the beach, there are various sections that are visibly different from one another. These zones are due to seaweed, the size, density and more obviously colours. The most common colour seaweeds are browns, from the phaeophycae family. During the day, as tides come and go, the …

The ‘Stroop Effect’ was first introduced in 1935. It originated from the theory of automatic processes. It is clear that some processing activities become automatic as a result of prolonged practice eg. Typing, driving, etc. Automatic processes therefore are fast, require no attention and are unavoidable. Stroop believed that there …

Conclusion and Evaluation: The results support the hypothesis stated above, as the temperature of the water rises, the volume increases as well. The volume does not increase proportionally with the temperature. The graph shows that the results I measured were not very accurate since the absolute zero I obtained after drawing …

Obedience is when someone does what a person or rule tells him or her to do. People tend to follow orders of an authority, and this can sometimes result in a negative effect. An example would include all those people who were obedient to Hitler, and killed innocent people in …

To investigate the effects of change in concentration on the rate of reaction between Sodium Thiosulphate and Hydrochloric Acid. Briefly describe your Preliminary Experiment and include your results. Explain how these results have helped you plan your main experiment (p8b). An increase in concentration will lead to an increase in …

Title: Determination of the vitamin C content (ascorbic acid) of a commercial vitamin C tablet and compare the result with the value specified by the manufacturer. Theory : In this experiment, we have to determine the vitamin C content of a commercial vitamin C tablet which is the mass of …

Abstract Zajonc (1965) describes Drive Theory as the increase in levels of arousal in the presence of others which enhances the frequency of dominant behaviours. The aim of this experiment was to challenge Zajonc’s theory. This study encompassed ten University students and ten teachers and examined the effect of an …

Scientific Knowledge: Before doing the experiment I came to the conclusion that this experiment relates to Hooke’s Law which states that extension is proportional to the load, meaning that if you stretch something with a steadily increasing force, then the length will increase steadily too. By looking at various sources …

Objective: The benefit of this lab was to acquaint oneself with the fundamentals of the Aldol Condensation reaction by demonstrating the synthesis of dibenzalacetone (trans, trans-1,5-Diphenyl-1,4-pentadien-3-one) through the aldol condensation of acetone with benzaldehyde. The synthesis began by using a strong base to generate the acetone enolate ion. The ketone/enol …

Introduction In the experiment the magnesium reacts with the hydrochloric acid to create magnesium chloride and hydrogen. The balanced formula for this is: Mg(s) + 2HCL(aq) MgCl2(aq) + H2(g) Magnesium + hydrochloric acid Magnesium Chloride + Hydrogen Magnesium will react with hydrochloric acid, because it is higher in the reactivity …
