1. Air conditioners not only cool air, but dry it as well. Suppose that a room in a home measures 6.0m×8.0m×2.5m. If the outdoor temperature is 30 ∘C and the vapor pressure of water in the air is 85 % of the vapor pressure of water at this temperature, what mass of water must be removed from the air each time the volume of air in the room is cycled through the air conditioner? The vapor pressure for water at 30 ∘C∘C is 31.8 torr. Express answer in two significant figures.

2. Four ice cubes at exactly 0 ∘C with a total mass of 52.0 g are combined with 135 g of water at 90 ∘C in an insulated container. If no heat is lost to the surroundings, what is the final temperature of the mixture?

Water is boiled and is put to cool. The temperature of the air in the room is rising linearly in relation to the function T(t)=30+0.01t, where t is minutes and T is Celsius. Suppose this satisfies Newton's Law of Cooling: the change of temperature of the water is proportional to the difference of the water temperature and the room’s ambient temperature. We take the water's temperature 10 minutes after and find that it's 81*C. Graph and explain T. Establish and...

A student observes that a 126 mL dry flask with a foil cup weighs 50.162 g. The student then adds 5 mL of an unknown volatile liquid and heats flask in a boiling water bath at 99.2 C Until all liquid disappears. The flask, foil, and unknown after heating that is dry and cool weigh 50.610 g. The barometric pressure in the laboratory is 743.3 mmHg; the laboratory temperature averages 22.3 C; the vapor pressure of the unknown liquid is...

1) Use Henry's law to determine the molar solubility of helium at a pressure of 1.9 atm and 25 ∘C. Henry’s law constant for helium gas in water at 25 ∘C is 3.70⋅10−4M/atm. 2) A 2.800×10−2M solution of NaCl in water is at 20.0∘C. The sample was created by dissolving a sample of NaCl in water and then bringing the volume up to 1.000 L. It was determined that the volume of water needed to do this was 999.2 mL...

Procedure Reaction 1: Dissolving the Copper 1. Obtain a clean, dry, glass centrifuge tube. 2. Place a piece of copper wire in a weighing paper, determine the mass of the wire and place it in the centrifuge tube. The copper wire should weigh less than 0.0200 grams. 3. In a fume hood, add seven drops of concentrated nitric acid to the reaction tube so that the copper metal dissolves completely. Describe your observations in the lab report. (Caution, Concentrated nitric...

Chemical Reactions Types and Their Equations Making Heat with Chemical Reactions Have you ever wondered how an instant heat pack works? A disposable heat pack works by a chemical reaction that combines iron in the package with oxygen from the air when the outer packaging is removed producing iron oxide. You have probably seen the product of this reaction in what is commonly called rust. The reaction releases heat, which allows the pack to reach a sufficient temperature that is...
