Goal(s): To study the effect of concentration on the rate of a reaction‚ and to find the order of the reaction in each reactant and write a rate equation. Background Theory: Chemical reactions occur at different rates that ultimately depend on their concentration‚ the temperature‚ the usage of catalysts‚ the nature of reactants‚ like the surface area of the particles. Concentration‚ for instance‚ increases the number of molecules or particles in a certain volume‚ so collisions will become more

oxygen‚ carbon dioxide‚ helium‚ and lab gas. We took a Ziplock bag‚ and turned into a non-stretchy balloon‚ and filled with each gas and measured the apparent mass then calculated the actual mass‚ then find a ratio between the mass of oxygen and the other gasses. We tried to keep the pressure about the same each time so our calculations would be more accurate. We found out that the heaviest was carbon dioxide‚ and the lightest was helium. In fact‚ helium and lab gas had a density below 0. Anyways

Celestial Geography I Emily Richarz PH090-04 Purpose: The purpose of this lab was to introduce us to star charts and how to use them to find stars‚ constellations and other bodies in the sky. Procedure: The instructor gave a brief but thorough lecture and demonstration on how to go about finding the answers on the worksheet. We then filled out the worksheet that cover finding stars and constellations using right ascension and declination in general and on specific dates‚ where constellations

activation energy of a reaction‚ the amount of energy needed to undergo a specific reaction. This will make the reaction happen much quicker because less energy is needed. Different enzymes have different threedimensional shapes with an active site‚ a cleft or depression. Substrates will bind to the active site of an enzyme if it is the correct shape. This makes it easier for the molecules to react. However‚ there are inhibitors that will prevent the substrates from binding to the active site. Inhibitors do

BIomes are distinct from habitats‚ because any biome can comprise a variety of habitats. In our lab we had figure out the major components in a biome. For example‚ like the weather‚ what animals live in it‚ plant life‚ etc… And answer key questions to why something happens in a Biome. And how species and plant life depend on each other to survive

Wanni Lin Biology 110 March 2‚ 2015 DNA Lab BACKGROUND In this laboratory experiment‚ students were introduced to DNA electrophoresis. DNA electrophoresis is an instrument that many forensic scientists use to get a DNA fingerprint as an evidence for crimes. Not only can it be used for forensic science‚ people can use this for paternity test‚ as well as look for evolutionary relationships among organisms. Agarose is used to make the gel that the DNA fragments are going into. Since DNA particles are

Fly Lab Shannon Ladd Introduction: Famers and herders have been selectively breeding their plans and animals to produce more useful hybrids for thousands of years. It was somewhat of a hit or miss process since the actual mechanisms governing inheritance were unknown. Knowledge of these genetic mechanisms finally came as a result of careful laboratory breeding experiments carried out over the last century and a half. A contributing geneticist named Gregor Mendel (1822-1884)‚ discovered through
