A 78.3g piece of gold at 650. K is dropped into 183g of H2O(l) at 310. K in an insulated container at 1 bar pressure. Calculate the temperature of the system once equilibrium has been reached. Assume that CP,m for Au(s) and H2O(l) is constant at their values for 298 K throughout the temperature range of interest.
A gas expands and does P-V work on the surroundings equal to 325J. At the same time, it absorbs 127J of heat from the surroundings. Calculate the change in energy of the gas. How do I solve this?
from the IR, 1H NMR spectrum and uv values decide what functional groups are present in the compound and deduce any other structural information you can, such as existance of conjugation in the carbonyl compound.
