Electron Donor and Receptor in Metal Complexes, In the first step of the catalytic cycle, the alkene bonds to palladium to make a new metal complex The alkene is now a ligand because the pi-bond of the alkene is donating some of its electrons to p..
A 150.0-g sample of a metal at 75.0 °C is added to 150.0 g of H2O at 15.0 °C. The temperature of the water rises to 18.9 °C. Calculate the specific heat capacity of the metal, assuming that all the heat lost by the metal is gained by the water.
Calculate the specific heat was? Would your computed specific heat be , too low, too high or not affected if you had not dried the metal before placing it into the Styrofoam cup. Explain your answer?
