A Pb ( s ) | Pb 2 + ( aq ) | | Au 3 + ( aq ) | Au ( s ) Pb(s) | Pb2+(aq) || Au3+(aq) | Au(s) galvanic cell has a standard cell potential of 1.628 1.628 V. Calculate the Gibbs free energy change at 25 25 °C when 2.45 2.45 g of gold is deposited. Assume that the concentrations in the cell remain at the standard state values of 1 1 M through the entire deposition process.

The two naturally occurring isotopes of chlorine are 35cl (34.969 amu, 75.77%) and 37cl (36.966 amu, 24.23%). the two naturally occurring isotopes of bromine are 79br (78.918 rm amu, 50.69%) and 81br (80.916 amu, 49.31%). chlorine and bromine combine to form bromine monochloride, brcl. 1. how many peaks will be present in a mass spectrum for brcl? the four combinations of molecule possible given these four isotopes are: 81br37cl, 81br35cl, 79br37cl, and 79br35cl. 2. what are the masses of the four different brcl molecules? express the masses using six significant figures, in decreasing numeric order (highest to lowest), separated by commas.
