Investigating The Rate Of Reaction Between Marble Chips And Hydrochloric Acid Planning I will use marble chips and different concentrations of hydrochloric acid and water to see how it affects the rate of reaction. I will use concentrations of 50cm3 using different volumes of water and acid. Introduction I am investigating how the rate of reaction between marble chips and hydrochloric acid is altered when the concentration is changed. This is the word equation for my investigation

Title of Lab: Preparation and Assay of Phenolase and Peroxidase from Sweet and Irish Potato Hypothesis: Polyphenol Oxidase enzyme activity can be detected by change in colour of solution‚ Inhibitors prevent the reaction of the enzymes with substrates‚ the enzyme is relatively specific. Aim: To design and conduct an experiment to demonstrate enzyme activity of Polyphenol Oxidase and Peroxidase when mixed with catechol‚ caffeic acid‚ pyrogallad‚ tyrosine‚ guacol‚ and water‚ to test the effect of

On October 2nd‚ 2015‚ Wasilla High School and Palmer High School have a football Potato Bowl game. This is the last football game of the year and its the rivalry game. Anyways that day I was with a couple of my friends and streaking got brought into conversation. And one of them suggested I did it at the potato bowl‚ and I agreed. So I called a couple of people and asked if they wanted to do it. One Palmer boy and one Colony boy said that they would do it with me‚ so I went to the store and bought

1) Comment on the pros and cons of using CM-5 chips in SPR analysis (3 marks). CM-5 chips can provide a relatively high carboxylation of dextran matrix which develops high negative-charged surface that contribute to bind large amount of ligands. However‚ the high negative-charged surface may increase the chance of non-specific binding of other stronger positively charged molecules causing false positive signals. Covalent bound with the ligand through the EDC/NHS activation process

Being the chocolate chip in a cultural cookie was never easy. Everything about me stood out; whether it be my skin color‚ Dominican heritage‚ or name “Alejandro‚” I was astoundingly different. I was born to a Dutch-Canadian-American father and a Dominican mother. Needless to say‚ my household featured an interesting blend of cultures. Here in northern Michigan‚ I’m surrounded by beautiful lakes‚ forests‚ and the “Million Dollar Sunset.” My town is famous for its rich history‚ proximity to the great

concentrations of 0.0 mol dm3‚ 0.2 mol dm3‚ 0.4 mol dm3‚ 0.6 mol dm3 and 0.8 mol dm3 affect the osmolarity point of potato cells‚ where it is investigated how osmosis changes the weight of the potato cells‚ measured by the percentage change between the initial and final mass of the potato? Independent Variable: Increasing sucrose concentrations Dependant Variable: Mean percentage change in mass of potato cells All cells have a protective barrier‚ one which selectively allows substances to enter and exit

Separation Challenge Problem: Salt‚ sand‚ wood chips‚ iron filings Materials Needed: a magnet‚ water‚ a pot‚ clean flat surfaces‚ a burner‚ filter paper‚ a stirrer‚ and four beakers for each item in the mixture Plan Brainstorm: Separate the items one by one using their different properties. Final Plan: To separate sand‚ salt‚ wood chips and iron filings First‚ use a magnet to remove the iron. Since some sand/salt will get caught with the iron filings‚ you may have to spread out the separated

Aim: To investigate the effect to the potato cells in the different solute concentration water Introduction; Water can move through the different cells due to the difference of water potentials in the cells. If there is a higher solute concentration in the cell than outside the cell‚ the water will move into the cell. However‚ if the concentration of inside the cell is lower than the outside‚ water will not move into the cell. This process is called osmosis. Research question; This investigation
