Introduction We are going to do an experiment to see how surface area effects the rate of reaction when added to hydrochloric acid. I will add calcium carbonate (marble chips) to hydrochloric acid. When calcium carbonate is added to hydrochloric acid a reaction takes place. The solution fizzes and gives off the gas carbon dioxide. I will collect this gas in a gas syringe and will time how long it takes for the reaction to produce 100cm3 of carbon dioxide. CaCO3 +2HCL Co2 +CaCl2 +H2O CalciumHydrochloricCarbonCalciumWater

to do my Psychology project on does the color of paper affect memory? I chose this question because i thought it would very interesting and intriguing seeing the end results. My research question does in fact relate to the specialized area i chose. I chose the Experimental Psychologist because‚ it is broken down into a few branches one known as the cognitive psychologist. These Psychologists observe sensation‚ perception‚ learning‚ memory‚ thinking‚ and motivation. My research question relates because

Introduction In this experiment‚ we will be figuring out how much does 80 degree celsius water reduce in temperature in 15 minutes‚ using different materials to insulate the heat. The five materials that will be tested are: Aluminium foil‚ plastic wrap‚ newspaper‚ felt‚ and bubble wrap. Aluminium foil is a reflective material; this means that it bounces the thermal energy back to the foiled object. It also absorbs the heat. Not only does it stop heat loss‚ but Aluminium foil is also useful for protecting

Analyze the reasons why costs need to be controlled to budget. The important responsibilities are to be able to control budgets and costs and also make sure that they are making a positive financial input to the business. Business has costs in which different varieties of finance are used to cover different types of business costs. You should control costs if you want to earn more money‚ since the whole world is in recession now if you control costs now you can be in secure place. If still

Enzyme Lab Introduction/ Abstract An enzyme is a substance produced by a living organism that acts as a catalyst to bring about a specific biochemical reaction. They are mainly made up of proteins and can tremendously speed up reactions. E. coli ( a bacterium) has about 1‚000 different types of enzymes floating around in its cytoplasm at any given time. Enzymes can be used to join and even break up molecules as shown in the diagram below. (1)

Does War Affect Literature? Many writers use the environment‚ political issues‚ or social issues as inspiration to their work. During romanticism nature imagery was a common occurrence in literature. However does on particular issue effect writers so much that a new literature movement is sprung from it? I pose the question what were considerable differences between Victorian literature and Modernism and how did the Great War play apart in those differences? Was it because of the war that there

Bobby Chang English 1102 Warwick April 27‚ 2002 How does music affect one’s intellect? Music is said to affect the intellect of humans in several different ways. Specifically‚ it is said to affect infants more than any other age group. Music can improve learning skills‚ test taking skills‚ concentration‚ heartbeat‚ and relaxation. Music has been proven to offer several benefits for infants‚ young children‚ young adults‚ as well as for adults. With all of this in mind‚ how can one connect

It helps to improve the life span of the vegetation and animals living in it. With the rise in wildfires all over the country‚ researchers say that controlled burns will help reduce the risk of catastrophic wildfires. Many people think of fire as only being dangerous and destructive

[pic] Introduction Enzymes are catalysts which speed up a reaction by providing an alternative reaction pathway of lower activation energy. But they do not undergo permanent changes and so they remain unchanged even at the end of the reaction. Many enzymes consist of proteins and non-proteins called the cofactor. The intra- and intermolecular bonds that hold proteins in their secondary and tertiary structures are disrupted by changes in temperature and pH. This affects shapes and so the catalytic
