A silver block, initially at 58.5 0C, is submerged into 100.0 g of water at 24.8 0C, in an insulated container. The final temperature of the mixture upon reaching thermal equilibrium is 26.2 0C. What is the mass of the silver block?

Biology 221 Weeks 1 & 2 Notes Elements: o Pure substance of an atom o Cannot be broken down o Most common: Carbon, Nitrogen, Hydrogen and Oxygen Atom: o Smallest unit of matter o Same # of protons=same element o Subatomic Particles Protons (+) Electrons (-) Neutrons (Neutral) # of protons=# of electrons (Except in ions) Nucleus: (Only in Eukaryotic cells) genetic material surrounded by a cell membrane. Atomic Mass: # of protons + the # of neutrons Atomic Number: The # of protons only. Isotope: Same # of protons but a different atomic mass, due to the # of neutrons. o Often are very unstable
