Assuming 1.0 L of 2.0 M Cu21 in the copper compartment, calculate the moles of NH3 that would have to be added to give a cell potential of 0.52 V at 258C (assume no volume change on addition of NH3).

a pan containing water is placed in a positio n where it is exposed to a 10 mile per hour wind. the pan contains a uniform depth of 1.27 cm of water, is quite wide, and has a length of 2.44 m in the wind direction. the water in the pan is at a constant temperature of 15.5 °c.

catya that's not even a b or c

answer: mole of the gas

answer: mole of the gasexplanation:
