1. The molar heat capacity of copper at 1 atm., in Joules/(K-mol) over the temperature range 100 to 200 K can be approximated as Cm = 0.23 + 0.21 T - 0.00047 T² where T is the temperature in Kelvin. Calculate AH and AS for heating 2.00 moles of copper from 100 K to 200 K at a constant pressure of 1 atm. p.m

Based on this. What mass of water was driven off by heating? (Grams)

In order to synthesize the following ethers using the Willamson synthesis method, what would you need as starting material? DA. This ether cannot be synthesized using the Williamson method, but it can be done through electrohilic and nucleophilic substituions using fuming sulfuric acid as a catalyst. В. он Br OC. Br HO.

How many grams of oxygen (O) are present in a 6.41 g sample of potassium nitrate (KNO3)? Enter your answer in decimal form with the correct number of sig figs. Use the proper abbreviation for the units. NOTE:  If you have taken chemistry before and know what diatomic means, do not take that into consideration.  Use just O for this.  There are reasons for this.
