• ## A gray-scale digital camera with 1,000,000 pixels takes a picture (the picture is made of 1,000,000 parts and each part has a certain amount of gray). A histogram is made where the data is the amount of gray in each of these parts. The histogram looks bell-shaped with a mean of 125 gray levels and a standard deviation of 15. Approximately how many pixels have a gray scale of between 110 and 140? A. 30 B. 500,000 C. 680,000 D. 950,000

• ## Which shows the correct relationship? A.) Eo cell > 0 = nonspontaneous reaction B.) Eo cell > 0 = spontaneous reaction C.) Eo cell = 0 = nonspontaneous reaction D.) Eo cell Answer: B.) > 0 = spontaneous reactionExplanation:The standard emf of a cell is related to Gibbs free energy by following relation: = gibbs free energyn= no of electrons gained or lostF= faraday’s constant = standard emfwhen = +ve, reaction is non spontaneous= -ve, reaction is spontaneous= 0, reaction is in equilibriumThus reaction is spontaneous when = +veThus reaction is non spontaneous when = -veThus reaction is in equilibrium when = 0.
