Two chemicals are available. One is called Sodium Borate Decahydrate and the other is called Aluminum Chloride Hexahydrate. Each can serve as a readily available soucre of water. Two students attempt to collect water from the hydrates. Lisa uses the Sodium hydrate given, while Michael uses the Aluminum hydrate given in the problem. Lisa uses 437 grams of the Sodium hydrate. That being the case, then determine how many grams of the aluminum hydrate hydrate Michael will have to use...

A sheet of aluminum weighing 100.0 g and at a temperature of 50.0 C is placed in contact with a piece of copper weighing 100.0 g and at a temperature of 100.0 C. 1) What do you expect to happen? Which metal is going to get warmer? Why? If you did not have a thermometer on the blocks, what visual cue would let you know one is hottter than the other? 2) Will the final temperature just be average of...

1) Back in the day, aluminum was a highly precious metal. It was first isolated by Hans Charistian Oersted (or possibly Friedrich Wohler, who believed Oersted to not have succeeded) in the early 1800s. Its synthesis involved the reaction of aluminum chloride with potassium: 3K + AlCl₃ → Al + KCl₃ The Baron Von Markov has decided that he wants a full aluminum place setting, and you have been put in charge of making the required aluminum. You have to...

Imagine that you have two pieces of different types of metal of the same mass. You then perform the following experiment. You take 500 ml of water in a well-insulated beaker with a diameter of 75 mm at 20.0+/-0.05°C. The two masses are heated to 100 +/- 0.05°C. Metal A is place in the water container. After waiting some time, you find that the temperature of the system stabilizes at 24.8+/- 0.05 °C. You then add metal B to the...

1. The shorter the wavelength of a photon, the more the photon behaves like a particle. Why? 2. In a H2 molecule there are two protons, and these have spin 1/2 ħ, that is, they are fermions. If we just look at the two protons, would you expect their spins to be parallel or anti parallel in the ground state of the H2 molecule? 3. Is there a type of viscosity that acts on holes in a semiconductor and gives...

Asteroids can be classified into two broad groups based on their composition and location: carbon-rich asteroids dominate the outer part of the asteroid belt, whereas metal-rich asteroids dominate the inner part of the belt. Analysis of the fragment we have discussed in this project reveals that it contains nearly equal amounts of metals and carbon. Can you conclude that the original whole asteroid had a similar composition? Can you conclude with a high degree of confidence that the asteroid originated...

The Problem: In this assignment, students are required to implement a simple communication between two entities (that is, device-to-device or device-to-server, depending on the selected protocol) using any two of these protocols. The information to be exchanged in this communication can be simple (a text of one line) or complex (a large text, audio, or video file). General Rules: 1. Students are required to work in teams of three with only one team being of two. 2. Teams are required...

Suppose two of the parts Company X produces are Widgets and Gadgets. Each has a marginal cost of $50. Widgets has a price elasticity of 2 and Gadgets has a price elasticity of 4, both in absolute value terms. Compute the profit maximizing prices of both Widgets and Gadgets, and show your work. (8 points) If the Widgets Market experiences entry of competitors, would you predict any change in price elasticity of Widgets? If so, in which direction, and why?...
