We conducted a lab in which we had to determine the molecular weight of a volatile liquid. My professor wants us to explain why Graham's Law of Effusion works for this procedure? The experiment consisted of us heat up a test tube with a volatile liquid. The lid of the test tube was covered in tin foil with a pin hole to allow for the gas to escape. Please don't just define Graham's Law. Tell me why it works here.

An experiment was conducted to determine if there was a mean difference in weight for women based on type of aerobics exercise program participated (low impact vs. high impact). Body mass index (BMI) was used as a blocking variable to represent below, at, or above recommended BMI. The data are shown as follows. Conduct a two-factor randomized block ANOVA (alpha = .05) and Bonferroni MCPs using SPSS to determine the results of this study. Subject Exercise Program BMI Weight 1...

To determine the molar mass of a volatile liquid, we used the Dumas method with a test tube, tin foil cover, and hot water bath to convert the liquid to a gas and then measure its pressure, temperature, amount, and volume. a) Why must you leave the test tube in the hot water for several minutes before taking a reading and removing it? What is happening during this time? b) How was the experiment designed to ensure the pressure of...

A study was conducted to determine the effectiveness of a diet program in reducing weight of obeys people. Eight randomly selected patients were put on this diet and the amount of weight losses (in pounds) were recorded. Suppose the sample mean and the sample standard deviation of weight losses were 38 and 4.598136 pounds, respectively. Construct a 90% confidence interval for the average weight loss and based on the confidence interval constructed determine if you would expect to see an...

For today's lab we will be using the Car Object Class which we built in Lab 1. I have attached my solution if you would prefer to use my solution instead of your own solution. We will working on remembering how to build sub-classes and user interfaces.

Although multiple molecules are important in modern molecular labs, in Genetics Lab, we will be focusing on DNA. Throughout the semester, our treatment of the DNA can determine if we are successful or not in meeting our experimental goals.   You are going to consider several treatments that might affect DNA shape/form/function. We use some of these treatments on purpose in order to manipulate our DNA, but sometimes we avoid these treatments to keep from harming our DNA. You will be...
