out so that tubes containing a reaction solution of the Amylase enzyme and starch were simultaneously mixed. The reactions were then introduced to I2-KI‚ which stopped the reactions‚ at two minute intervals. Each of these trials was repeated three times to ensure proper accuracy. After concluding the reactions they were placed into a spectrophotometer (A580) for analysis. Graphing the values of the absorbance to time for each pH it was found that the rate of reactions in the neutral pH solutions were

experiment was conducted to accomplish the following objectives. The first objective aims to synthesize an isomer of alkenes. This was done by converting maleic acid to fumaric acid. This conversion was accomplished by applying a heat-catalyzed reaction on maleic acid diluted in distilled water and mixing it with HCl using a reflux set-up. A reflex set up is a distillation set up wherein the set up differed because it is inverted vertically. This was done in order to break the pi bond to allow the

Michigan entrepreneur Justin Eric Sutton brings us into the era of clean hydrogen energy and solar energy‚ by producing a remarkable high speed MAGLEV railway which is being sold throughout the USA for deployment on Elevated Superhighway Rails‚ it speeds travelers between metro areas at up to 250+ MPH‚ in this remarkable vision of the not so distant future! Not only would it revolutionize energy AND transportation‚ it is both feasible and deployable TODAY. All that remains is funding and agreements

Chemist from the University of Glasgow in Scotland have taken a step closer towards producing clean hydrogen fuel in a maintainable way. Hydrogen gas is able to be burned to generate electricity without producing lethal releases‚ unlike fossil fuels. It is produced from water releasing them as gas‚ through a process called electrolysis‚ which uses electricity to break the bonds between hydrogen and oxygen. This technique is 30 times faster than the current method‚ and can be powered by renewable

Unit 01- Child and Young Person Development (1.1) 1. Explain the difference between sequence of development and rate of development and why the difference is important. (1.1) It is important to know the difference between the sequence and the rate of development as it gives us direction when it comes to monitoring child/young person’s needs during stages of their school years. We can then plan effectively to make sure the child receives the help and support they need in areas they could find difficult

The question I will be investigating is on how fast ice melts in different liquids. The liquids being tested are water‚ salt water‚ hydrogen peroxide‚ and Pepsi. The ice will be placed in each of these liquids when the liquids all reach room temperature. Some people assumed that Coca Cola would melt the ice the fastest because of it’s carbonation. But when tested they found that at room temperature water melted the ice the fastest(2). Another person tested how fast water‚Sprite‚ and orange juice

business idea I would use is that I looked at what the community wants. The other is that I have asked friends and family for their ideas and which frustrations they have about current products and/or services? Business ideas have a higher success rate if the people you tell your idea to are enthusiast about it. This because they can be one of your future customers. So if they say they would buy your products‚ the change that someone else would buy it is more realistic. I have brainstormed with

on the graph show that there is a strong positive correlation between the average rate of conductivity and the surface area: volume ratio. As the surface area of the Agar cube increases‚ the rate of conductivity will steadily increase‚ too. The trend line of the graph shows as an exponential graph because at one point there will be no more conductivity due to too small or too big Agar cubes. A difference can be seen in the average rate of conductivity depending on surface area because the Agar cubes

Metals and Halogens reactions Elements such as fluorine‚ chlorine‚ bromine‚ iodine‚ and astatine belong to Group 7‚ Halogens. At room temperature‚ fluorine is a yellow gas‚ chlorine is a pale green gas‚ bromine is a red liquid‚ and iodine is a purple solid. Astatine is a radioactive element‚ therefore it exists only in small amounts. All the halogens exist in diatomic molecules. They have high ionization energies and are the most electronegative elements. Their electron configuration ns2 np5 make

We will use basic lab equipment provided in our Labpaq‚ and follow all safety precautions in this lab. From reading the discussion and review‚ we understand that the normal configuration of the electrons is called “the ground state”. We understand that they are
