Experiment to investigate the effect of concentration of electrolyte on the current of voltaic cell Aim The aim is to identify the relationship between the concentration of H2SO4 solution and the current of Cu-Zn voltaic cell. Hypothesis My hypothesis is that the greater the concentration of sulfuric acid the bigger the current of the voltaic cell. In a voltaic cell‚ chemical energy is concerted to electrical though the oxidation and reduction happen on the electrodes. Current will not flow

THE EFFECT OF GLUCOSE CONCENTRATION ON ANAEROBIC RESPIRATION IN YEAST INTRODUCTION: Yeast‚ also known as a saccharomyces cerevisiae‚ is single celled eukaryotic cells that are in the kingdom fungi and are unicellular organisms which normally reproduce asexually by budding at a very high rate. Scientists quite often decide to work with yeast because of its features fast growing rate and the fact that yeast ’s DNA can be easily manipulated. Some types of yeast can be found naturally on plant or in

Auschwitz concentration camp. Furthermore‚ it was three different types of camps that were brought together: concentration camp‚ extermination‚ and labor camp (“Auschwitz was the largest camp”). All three camps played a major part in the Nazi’s “final solution” (Berenbaum). There were also subcamps part of Auschwitz. In just two years‚ 44 subcamps were built (1942 to 1944). Auschwitz also had different leaders. The first of the three leaders who controlled all of the Auschwitz concentration camps was

Effects of Sucrose Concentration On Cell Respiration In Yeast Abstract This lab investigates the effects of Sucrose concentration on cell respiration in yeast. Yeast produces ethyl alcohol and CO2 as a byproduct of anaerobic cellular respiration‚ so we measured the rate of cellular respiration by the amount of CO2 produced per minute. The results show a trend wherein increased concentrations of sucrose increase the rate of cellular respiration. Introduction All living cells require energy

permeable membrane through a process of diffusion. The movement of a solute through this membrane is called dialysis . Diffusion is a form of passive transport. It is the movement of molecules from areas of higher concentration to those of lower concentration‚ until there is an even concentration. This movement is random because it is a result of kinetic energy. Diffusion is a slow process‚ but there are many factors that will affect it’s rate. The rate of diffusion will vary depending on the size of the

Determining the Unknown Concentration of NaHCO3 (aq) Through Titration Introduction Titration is the accurate addition of a titrant- solution in a burette- into a measured volume of a sample (Kessel‚ 2003). There are many different types of titration‚ such as acid-base reaction‚ redox reactions‚ precipitation reaction and more (Dohrman). In this lab an acid base titration will be explored. In an acid-base titration‚ the concentration of an acid or base is unknown and is determined by the adding

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

“Between 1.1 and 1.5 million people died at Auschwitz; 90 percent of them were Jews” (“Auschwitz”). Concentration camps were large numbers of people; mostly Jews enduring forced labor and mass executions. One of the concentration camps during the Holocaust was Auschwitz. Auschwitz-Birkenau had a unique design‚ a horrible daily life for those in it‚ and is greatly remembered for what happened at these camps at the end of the war. Nazi Germany set up camps with a specific design that would help them
