Determine the pressure in a 14.6 L cylinder filled with 0.440mol of N2 gas at a temperature of 327K.
A 4.10 g nugget of pure gold absorbed 274 J of heat. What was the final temperature of the gold if the initial temperature was 27.0°C? The specific heat of gold is 0.129 J/(g·°C).
Using data from the Appendix, calculate the temperature where Keq = 1.00. You may assume that deltaH0 and deltaS0 are independent of temperature.
Consider the cell described below. Al | Al3+ (1.00 M) || Pb2+ (1.00 M) | Pb Calculate the cell potential after the reaction has operated long enough for the [Al3+] to have changed by 0.32 mol/L. (Assume T = 25°C.)
