Exactly 313.5J of heat energy will raise the temperature of 10.0 g of a metal to 60.0 C. IF the specific heat of the metal is 0.896J/gC, what was the initial temperature of the Metal
describe the coordination geometry e.g. octahedral for each metal ion and the mxnlm formula for deoxy and oxy form of
How many kilojoules are needed to raise the temperature of 125 g of copper from 22 deg C to 325 deg C? My book shows copper at 0.385 j/g. Here is what I have done so far but I am not sure? 125 g x 303 deg C x 0.385 j = 14600. j 14600/1000 = Conver..
