Iwant to use a galvanic cell to power a 60-watt light bulb. complete the following steps to determine how long the galvanic cell will power the light bulb before running out.
a.) the galvanic cell uses the following solutions: 0.81 l 1.5 m cr2(so4)3 solution and 1.2 l 0.81 m au(no3)3 solution. write down the balanced chemical equations of the dissolution of cr2(so4)3and au(no3)3 into ions in water.

Explanation:

On dissolution of chromium(II) sulfate is water 2 ions of chromium(III) ion and and 3 sulfate ions are formed.

The balanced chemical equations of the dissolution of chromium (II) sulfate:

On dissolution of gold(III)nitrate is water 1 ions of gold(III) ions and and 3 ions of nitrate ions are formed.

The balanced chemical equations of the dissolution of gold(III) nitrate:

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.
