A copper, Cu(s), electrode is immersed in a solution that is 1.00 M in ammonia, NH3, and 1.00 M in tetraamminecopper(II), [Cu(NH3)4]^2+. If a standard hydrogen electrode is used as the cathode, the cell potential, Ecell, is found to be 0.085 V at 298 K.
Based on the cell potential, what is the concentration of Cu^2+ in this solution?
Since heat is an extensive property, the amount of heat that is produced depends on the amount of reactants utilized in the reaction. If you have more reactant then you will have more heat. Just think of a big fire cracker versus a small fire crac..
You use a properly calibrated explosimeter to measure the flammable hazard inside a tank that contained toluene and may still have some residual product a. inside.
Calculate the pH of a solution that is 1.00 M HNO2 and 1.00 M NANO2
List and describe briefly the 2 methods which are used by drug companies to discover lead compounds
