"Do different concentrations of solutions determine the mass of a potato?" Introduction: The way to get the full results of this lab was through the process of osmosis. Osmosis is the movement of water across a membrane into a more concentrated solution to reach an equilibrium. When regarding cells osmosis has three different terms that are used to describe their concentration. The first of these words is isotonic. Cells in an isotonic solution show that the water has no net movement and the amount

the effects of different factors such as temperature‚ pH‚ and concentration of substrate‚ on the activity of the enzymes. By conducting these three separate experiments also‚ three graphs are able to be obtained where the trend of each factor affecting on the enzyme activity is shown and described clearly. II. Hypothesis Experiment 1 (Effect of Temperature): As the temperature increases‚ the height of the bubble will increase too‚ indicating a faster rate of reaction. Experiment 2 (Effect of

Table setting or place setting refers to the way to set a table with tableware—such as eating utensils and dishes for serving and eating. The arrangement for a single diner is called a place setting. 2 types of table settings * Informal * Formal Informal setting is easier‚ involving the least amount of tableware as there are fewer courses involved. This is your basic everyday table setting‚ one that you might already set each night for dinner in your own home. Rules for a proper

Hazardous Chemical Mustard Gas Imagine sitting in a trench during World War 1 with your fellow soldiers and someone shouts‚ “Incoming!” you duck deeper into the trench and fumble for your helmet‚ not realizing that it could be your last seconds on this earth. Instead you smell a pungent mustard aroma‚ struggling to breath‚ it subsides after a couple of minutes. Without knowing it you have been exposed to a new chemical used by the Germans‚ code named LOST‚ which referred to the last names of the

Among primary manufacturing industries‚ for example‚ paper manufacturing is the fourth-largest user of energy and the largest generator of wastes‚ measured by weight.1 The paper industry and the nation’s environmental laws have done much to reduce the environmental impacts of pulp and paper manufacturing over the last 25 years. In this resource-intensive industry‚ however‚ environmental issues will always be an intrinsic

Auschwitz concentration camp Auschwitz concentration camp was a network of concentration and extermination camps built and operated by the Third Reich in Polish areas annexed by Nazi Germany during World War II. It was the largest of the Nazi concentration camps‚ consisting of Auschwitz ‚ Auschwitz II‚ Auschwitz III‚ and 45 satellite camps. Auschwitz I was the original camp‚ serving as the administrative center for the whole complex. The site for the camp had earlier served as Austrian army and

The Effect of Increasing Temperatures on the Enzyme Catalase Enzymes are proteins that help speed up chemical reactions inside your body and without enzymes‚ chemicals reactions in cells would be incredibly slow to a point where no activity at all takes place (Brawo press Inc‚ 2017). Enzymes speed up the chemical reactions by lowering the activations energy and they do this by binding substrates together in the correct orientation to react (Ernest Z‚ 2014). They are vital for life and serve a

Table Tennis Table Tennis The Table Tennis sport got its start near the end of the 19th century in England. After dinner one night‚ some Victorians decided to turn their dinning room table into a miniature version of lawn tennis. They lines up books as a net‚ used lids from empty cigar boxes as rackets‚ and the ball was made from string (table tennis balls were also made from champagne corks or rubber). Started as an after dinner activity‚ over the years‚ table tennis would turn into a sport

Effects of Different Concentration of Catalyse on Hydrogen Peroxide Aim: In this investigation I will try to find how long it takes for the filter paper disc to rise up whilst varying the amounts of concentration of catalyse. Prediction: I predict that the lower the concentration of catalyse the longer it will take for the filter paper disc to rise to the surface of the tube. Equipment: 1. Hydrogen peroxide in a container 2. Flat bottom tube 3. Tweezers 4. Filter paper
