A radiation detector exposed to sunlight records the energy falling on a given area each unit time. If such a detector has a reading of 0.698 cal cm-2 min-1, how many photons of sunlight are striking each cm2 in one minute?Assume the average wavelength of sunlight is 460. nm. (4.184 J 1 calorie)A. 1.62 x 1018 photonsB. 4.32 x 1019 photonsC.6.76 x 1018 photons D 2.31 x 1018 photons E 9.63 x 1019 photons

Astudent made the lewis dot diagram of a compound shown. what is the error in the lewis dot diagram? a)an o atom should transfer all of its six electrons to mg because the formula is mgo b) both electrons of mg should be transferred to one o adam because the formula is mgo c) the electrons should be transferred from each o add him to capital mg because mg has fewer electrons d) the number of dots around mg should be four because it has to transfer two electrons to each o
