- Average Mass of Pintobeanium: 2830.00 mg/6= 471.67 mg
- Average Mass of Blackeyedpeaium: 1110.00 mg/5= 222.00 mg

- Relative Abundance of Kidneybeanium: 3/14= 0.2143
- Relative Abundance of Pintobeanium: 6/14= 0.4286
- Relative Abundance of Blackeyedpeaium: 5/14= 0.3571

- Relative Weight of Kidneybeanium: 553.33 mg x 0.2143 = 118.58
- Relative Weight of Pintobeanium: 471.67 mg x 0.4286 = 202.16
- Relative Weight of Blackeyedpeaium: 222.00 mg x 0.3571 = 79.28

A port expander is a hardware device designed to allow a user to utilize more than one device on a single port at one time. There are two basic forms of port expanders: internal and external. An internal expander has a connection inside the computer and the only part that is visible to the user is the expansion plate containing multiple ports. An external device plugs into the existing port and then has multiple places to connect. Expanders are made for nearly every type of port, but the most common household versions are for universal serial bus(USB) and Ethernet ports.(What Is a Port Expander?, 2013)…

Chemical kinetics, which can also be explained as reaction kinetics, studies the rates of chemical processes and reactions. A lot of this has to do with the speed at which a chemical reaction occurs for instance the rate at which reactants and products appear and disappear. In this case chemical kinetics goes further in depth to understand what conditions affect the rate of a given reaction. This is important because it allows scientists to determine what type of reaction can occur, and how they can alter the outcome under varying conditions. Gasoline and diesel for example have two very different reaction rates when exposed to a spike in temperature. If you were to light gas on fire it would instantaneously explode igniting fumes in the air as well, however diesel has a much higher ignition temperature allowing it to slowly burn if lit. These two types of fuel are an example of the differences in reaction rate. To determine the rate at which these reactions occur we use the rate law: r=kAxBy. In this equation we are looking to solve for the rate of the reaction “r”, the k value which represents our rate constant is simply the value which quantifies the speed. As for the [A] and [B] values they are the concentration of the species A and B which respectively are raised to the “x” and “y” power. The “x” and “y” values are the respective stoichiometric coefficients that must be determined experimentally. The primary goal essentially for this experiment is to determine the k value or rate constant along with the x and y stoichiometric coefficients given the concentrations of Crystal Violet and Hydroxide. This can be obtained using a spectrophotometer to determine rate of absorbance then graph the rate find a line of best fit, determine our rate constant, then finally solve for our x and y in the rate law equation. Beer’s law also known as Beer-Lambert law relates the absorption of light to the properties of the material through which the…

In this experiment the student will need a Bunsen burner, ring stand, wire gauze, pH meter, red cabbage, about seven small beakers (clean), seven test tubes, universal pH paper, both red and blue litmus paper, methyl red and several solutions provided by the instructor. First the student will prepare the red cabbage by filling a beaker with 50 mL of distilled water and placing about 1 gram of finely chopped red cabbage and boil for 10 minuets. Let the beaker cool and decant the solution from the cabbage. While the cabbage is boiling the student should continue with the rest of the experiment, pour about 2 mL into the beaker and test the pH with the pH meter, litmus papers, and universal pH paper and record. Pour half of the solution into a test tube and set aside. With the sample in the beaker add 2 drops of methyl red and record. With the solution in the test tube add a dropper full of the cabbage indicator and record. The student must do these steps with all of the solution provided for in this experiment.…
