You are working in an alternative fuels laboratory and have been asked by your supervisor to determine the efficiency of photosynthesis for a plant that is being considered as a source of biofuels. you know that the plant produces the equivalent of 24 kg of sucrose per hectare per hour. you also know that sun supplies energy at a rate of 1.0 kilowatt per square meter of surface area. assume that sucrose is produced by the reaction: 12 co3 (g) + 11 h2o (g) ? c12h22o11 (s) + 12o2 (l) ? h = -5640 kj

Explanation:

Moles of sucrose =

                       =

                        =

                        =

Energy required for photosynthesis = 5640 kJ/mol

Energy needed to produce 24 kg sucrose

         = Energy required for photosynthesis x Moles of sucrose

          =

          =

Energy supplied from sun =

                                            = 1

Efficiency for photosynthesis =

                              =

                             =

                              = 1.098%

Thus, we can conclude that efficiency of photosynthesis for a plant that is being considered as a source of biofuels is 1.098 %.

let that person have a turn to speak : )

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.
