Investigate How Red Bull Energy Drink Affects The Reaction Time of 18-19 Year Old Human Males. DESIGN Introduction Substances that humans intake in food or drink contain various chemicals that affect the normal bodily functions of the consumer. Stimulants are drugs which when absorbed into the body raises physiological or nervous activity. The Red Bull Energy Drink is a stimulant‚ which contains psychoactive ingredients such as taurine‚ glucuronolactone and caffeine. Sportsmen and people requiring

A reaction is a chemical process in which substances decomposes‚ or combines with other substances. In this case it is synthesis chemical process which creates new products. However‚ the rate of a reaction can be altered either faster or slower depending on certain variables. These variables are concentration‚ temperature‚ surface area‚ and catalysts. A reaction can be made faster or slower with a variation in the concentration of reactants; a reaction goes faster when there is an increase in concentration

Does concentration affect the speed of chemical reactions? Problem: We are proving that “concentration” (the amount of reactants) is one of the things that can affect the speed of chemical reactions. We are also finding a way to keep the lid on the film canister for the longest period of time. We are using vinegar and water as reactants and changing the concentration every time to see the difference between the rates of reactions speed. Materials: - 1 graduated cylinder - 1 film canister

``Shakespeare Was Not OF An Age But For All Time`` I agree with the statement ``Shakespeare was not for an age but for all time. `` The words of praise probably the most famous ever written about Shakespeare ‚ were penned by Shakespeare`s good friend and follow writer `Ben Johnson`. For the poet and playwright generally considered the greatest ever is also one of the least known of all literary figures. And his works were indeed created for the popular entertainment of his day with little thought

The graph shows the time it takes for the cross on the bottom of the beaker while the reaction is recurring to disappear. As it can be seen in the graph‚ the higher the temperature the shorter the time is for the Sulphur to be created. If it is looked as one continuous line‚ the first part of the trend line shows a steep‚ straight and constant decrease; then the 2nd part is not as steep and has a more gradual decline. Moreover‚ it shows how a reaction at 20°C a slower time for the cross to disappear

revolutionary time in the dark? The Middle Ages were a revolutionary time that changed history forever and was very influential still to this day. Just because the times before and after the Middle Ages had very important events and literature doesn’t mean that the middles ages are of such lesser significance and should be referred to the dark ages. The Magna Carta was a big part of the Middle Age and is one of the most important documents‚ it influenced American government. During the Middle Ages trade

which both showed that an increase in concentration of the reacting species resulted in an increase in reaction rate. Both graphs have a positive gradient which clearly indicates that concentration increases the reaction rate. The hypothesis also proposed that as temperature increases the speed of the reaction would decrease‚ this is evidenced in graph 7 which shows a negative decrease in time as the temperature of the solution increases. This decrease can be modelled by the exponential formula T=12

Breland Crudup December 9‚ 2012 The Effects of Music on Reaction Time in Human Beings The Effects of Music on Reaction Time in Human Beings When performing many feats of physical skill‚ calculating how fast a person can perform the action has become a custom that has gained prominence in recent years. Observing how long it takes a person to perform an action‚ now known as observing the reaction time‚ has even gained enough importance to the point that it has even used in some scientific investigations
