Wow! The future is amazing. Wormholes allow travel to distant planets in a flash. In fact, you can vacation just about anywhere in the universe. I’ve been scoping out one planet in particular. The brochure says it has warm oceans, giant beaches, and incredible scenery, like nothing you’d see on Earth. The resort I want to go to is located in the planet’s Southern Hemisphere, and I want to make sure I go at the right time. Maybe you can . Here’s what I know. The planet, called Cryxxlyx, is tilted on its axis at 90 degrees relative to its sun. It takes about 400 days for the planet to complete one orbit of its sun. Does it matter when during its orbit I go to that resort? I’ve drawn a little diagram of the planet and its orbit. I’ve also marked the location of the resort. Remember, I want warm temperatures and lots of sunshine.
If a little old lady is doing 98.3 kilometers/hour, will she get a speeding ticket if the speed limit is 55 miles / hour? [USE: 5280 feet = 1 mile and 2.54 cm = 1.00 inch] (Show how to convert to miles / hour, even if your calculator does it for you.)
A chemist wants to extract copper metal from copper chloride solution. The chemist places 1.50 grams of aluminum foil in a solution of 14 grams of copper (II) chloride. A single replacement reaction takes place. What best explains the state of the reaction mixture after the reaction?
Unbalanced equation: CuCl2 + Al → AlCl3 + Cu (5 points)
Less than 6.0 grams of copper is formed, and some aluminum is left in the reaction mixture.
More than 6.5 grams of copper is formed, and some aluminum is left in the reaction mixture.
Less than 6.0 grams of copper is formed, and some copper chloride is left in the reaction mixture.
More than 6.5 grams of copper is formed, and some copper chloride is left in the reaction mixture.

A chemistry student is given 2.00 L of a clear aqueous solution at 43.° C. He is told an unknown amount of a certain compound X is dissolved in the solution. The student allows the solution to cool to 25.° C. At that point, the student sees that a precipitate has formed. He pours off the remaining liquid solution, throws away the precipitate, and evaporates the water from the remaining liquid solution under vacuum. More precipitate forms. The student washes, dries and weighs the additional precipitate. It weighs 0.062 kg1) Using only the information above, can you calculate the solubility of X in water at 25 degrees C?2) If yes calculate it. Round answer to 2 significant digits

4. During electrolysis, it is possible that corroded metals will stick to a particular anode
or cathode as electricity flows in solution. Suppose that I created a batter that uses a
silver electrode submerged in iron (III) nitrate, Fe(NO3)3, solution.
a. Write the complete, balanced chemical equation for this reaction below:
Write a chemical equation here.
b. How much elemental iron would be deposited over time on the electrode if 3
moles of iron (III) nitrate were present in the battery?
