JAVA Programming Assignment: You run four computer labs. Each lab contains computer stations that are numbered as shown in the table below:- Lab Number Computer Station Numbers 1 1-5 2 1-6 3 1-4 4 1-3 Each user has a unique five-digit ID Number. Whenever a user logs on, the user's ID, Lab Number, and the computer station are transmitted to your station. For example, if user 49193 logs onto station 2 in Lab 3, your system receives (49193, 2, 3)...

C. Analyzing an unknown base - optimizing a method: In this segment you will design your own method for analyzing an unknown base. In the solutions list there are several different concentrations of HCl to choose from. You can also try different sample volumes of the unknown base. Be sure to record these for each trial. Your goal is to find two different combinations of HCI...

Data in the table below summarize results from a replicated, two-factor lab test examining the effects of two different temperatures and two different lighting schemes on algal growth rates. Four treatments were applied, where +1 treatments refer of higher temperature or more light, and -1 treatments refer to lower temperature or less light. Use this information to conduct an ANOVA to examine the effects of temperature, light, and temperature light on the growth rate Light Replicates 114.059 97.079 89.089 47.959...

will work with up to 3 partners (similar to a lab group) to prepare a written report which analyzes kinetic data that has been provided to you. All student groups will receive data for the hypothetical reaction aAlE) products where a is a numeric variable and A is a chemical variable. The reaction therefore has the form of a decomposition reaction, in which a single substance forms one or more new substances. For consistency, all concentrations start out at 1.000...
