Plan a procedure that will allow you to compare quantitavely the glucose concentration in fresh samples of orange‚ lemon and grapefruit juice. Aim: The aim of this investigation is to produce a set of data which will enable comparison of the glucose concentrations of orange‚ lemon and grapefruit juice. Research: Benedict’s Reagent is a mixture of sodium compounds and copper sulphate. The copper ions are reduced by fructose (a reducing sugar) to form copper oxide‚ thus turning it from blue

We had started our experiment by learning about the change in the earth and what it does to the concentration in the oceans water. When global changes occur‚ they don’t only change that one thing it changes many things. Such as concentration in the water. For example‚ when heavy machinery or facilities burn fossil fuels‚ which releases more carbon dioxide in the air‚ the ocean sucks it up and the acidity in the water completely changes even if it goes up by .1 or .2 percent it’s still a lot and will

What Has Happened to Lulu? Louise Middleton‚ or Lulu‚ as she was fondly called by her mother‚ had been sitting on the hill for over forty minutes now. She bit her lip and found herself glancing around every time she heard a noise. Her fingers twitched and her heart was racing. Her mouth had turned dry but she forced herself to swallow. Suddenly‚ a shadow appeared on the ground in the distance. It began advancing towards her‚ growing longer and longer. Her heart pounded as she sat frozen‚ staring

The concentration camps was a place where people were detained and confined. The concentration camps are where they held jewish people against their own will. The concentration camps was where the Germans placed the Jews to hostage before killing them. There are three specific concentration camps that the Jews were sent too. The three concentration camps were the transit camps‚ forced labour or work camps‚ and extermination camps. Adolf Hitler just wanted to prove his power to everyone. The

authors actually experienced living in the culture of both places and developed relationships with the people they met. They were able to develop a point of view that no one would be able to without actually experiencing what these people experience. It gave us as readers a real look at what goes on in these cultures and we were provided with details that would only be picked up by actually being there. I think this makes the books more interesting and easier to learn from. Lila Abu-Lughod lived with the

The rate of fermentation is faster when there is more sucrose concentration because it means there is more glucose‚ which in return means more carbon dioxide production. The sucrose concentrations were 0%‚ 1%‚ 5%‚ and 10%. The 0% sucrose concentration is just normal‚ plain water. Yeast‚ a single celled eukaryotic fungi‚ was put into the solutions. It uses fermentation to make more carbon dioxide and alcohol. In the 0% solution‚ no carbon dioxide had been produced. At the start‚ the depth of the

THE EFFECT OF CONCENTRATION ON REACTION RATE INTRODUCTION • Concentration is one factor which has an effect o the rate of a chemical reaction. In chemistry we describe concentration in terms of the number of moles of a substance there are in every cubic decimetre (litre) of solution‚ written as moles.dm-3 of M for short. • In this experiment you will find out how increasing the concentration of the acid solution changes the rate of the reaction between dilute hydrochloric acid and magnesium
