to see how the change in concentration of hydrogen peroxide and the change in temperature affect the rate of reaction. The data will be collected by measuring the gas pressure. The product of Hydrogen Peroxide is oxygen in a gas state thus it is mandatory to use the gas pressure sensor. By calculating the difference of the gas pressure divided by the amount of time from the raw data collection it is able to find the rate of reaction of the decomposition of hydrogen peroxide. * Control Variable-

temperature‚ through heat transfer. The coefficient of thermal expansion describes how the size of an object changes with a change in temperature. Specifically‚ it measures the fractional change in size per degree change in temperature at a constant pressure. Several types of coefficients have been developed: volumetric‚ area‚ and linear. This is used depending on the particular application and which dimensions are considered important. For solids‚ one might only be concerned with the change along a

The scientist we chose for our project is John Dalton. Who is John Dalton‚ you might ask? John Dalton was an English chemist‚ physicist‚ and meteorologist. He is best known for the discovery of the modern atomic theory. The rules for the atomic theory are that all matter is made up of tiny particles‚ or atoms‚ atoms are always invisible and indestructible‚ all atoms of a given element are identical in mass and properties‚ compounds are formed by a combination of two or more different kinds of atoms

In this lab the volume of reaction space needs to be measured. I have chosen to use Magnesium and the amount of H2 gas that the amount of magnesium‚ (.04g)‚ used is 0.00229 mol H2. Procedure 1.

Conclusion: Boyle’s law states that for a fixed amount a gas at a fixed temperature volume is opposite to its pressure. The air in the marshmallow is what follows Boyle’s law. The marshmallow is similar to a gas because when the pressure in the syringe is decreased the pressure in the marshmallow is increased. The volume increases in the marshmallow. So basically when the plunger is pulled out the pressure in the syringe decreases and the volume of the marshmallow

stereotypes about each one of them began to pour out from each one of them. None of them had known each other previously‚ but they all had a stereotype tagged to one another. As they fought‚ they began to realize that the struggles‚ insecurities and pressures they had were the same ones that the people who seemed so different had. They touched on the lack of communication they all had with their parents. Their home life was not satisfying to them. This is very relatable to the viewer because everyone

The suction is created by an air pump‚ a partial vacuum; it creates a difference in pressure between the inside of the machine and the outside air and dirt and dust is taken in to the lower pressure zone. Friction on the carpet causes the dust to be removed from the carpet‚ or other surface. Table of Contents 1. History and developments - Ives W. McGaffey -Hubert Cecil Booth -James
