How many photons are contained in a flash of green light 525nm that contains 189KJ of energy?
To find the number of photons, we need to first calculate the energy of one photon using the formula E = hc/λ, where E is energy, h is Planck's constant, c is the speed of light, and λ is the wavelength. Then, we can divide the total energy (189 kJ) by the energy of one photon to get the total number of photons in the flash of light.
Determination of fe3 with EDTA by photometric titration?
Iron (III) ions form a deep-coloured complex with a maximum absorption at about 525nm; this complex is used as the basis for the photometric titration of iron(III) ion with standard EDTA solution.
Wh y are most producers green in color?
Chloroplasts in the leaves contain Chlorophyll which is used by plants to produce food and Oxygen through Photosynthesis Edited answer: When sunlight (or any short of light for that reason) falls on the leaves containing chlorophyll, it reflects the green spectrum of light. Therefore, all chlorophyll containing plants (being producers) are green in color.
The energy of one photon of light from electromagnetic radiation with a wavelength of 525 nm appears as green light to the human eye?
E=hc/l h=plank's constant c=speed of light l=wavelength [(6.626*10^34)(3*10^8)]/(5.50*10^-7)= 3.614*10^-19 for per mole (3.614*10^-19)*(6.022*10^23)= 2.18*10^5 muliply by .001 for kilojoules =2.18*10^2 or just 218 kj/mole
