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

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
