A sample of argon gas occupies a certain volume at 14 degrees C. At what temperature would the volume of the gas be three times as big? Assume the pressure stays constant.
how much energy (MJ) can be obtained from incineration and how much CO2 (kg/year) may be released in that year? 2) How much of that energy (MJ) can be actually converted into electric power if the conversion efficiency is 23%?
Consider the following chemical equation. Na3PO4(aq) + Ca(OH)2(aq) ? Ca3(PO4)2(s) + NaOH(aq) How many grams of calcium hydroxide must react to give 2.69 g of Ca3(PO4)2
A piece of metal of mass 20 g at 99?C is placed in a calorimeter containing 55.8 g of water at 23?C. The final temperature of the mixture is 30.4?C.

The MO diagram after the Jahn-Teller tetragonal distortion is added for a d4 high spin complex
You will start with 500 mg of one of isoamyl acloho to make isoamyl acetate. While the alcohols are liquids, we will measure them by mass directly on the balance, not by volume (i.e. the density of the alcohol will not be used; pretend the alcohol..
Draw the Lewis structures and determine which of these molecules has a central atom that violates the octet rule. Please note that NO3 has an odd number of electrons. But you must decide where the missing electron will be. Does the central atom vi..
