Problem- One application of emission in remote sensing is in the detection of forest fires. The Landsat satellite has a sensor that detects active fires by examining their emission in the wavelength region of 1.55 um to 1.75 um.
a. What type of light is being detected by this sensor?
b. What are the energies (in kJ/mol) for photons of light at these wavelengths?
Using textbook reference solve the reactions given in above problem
The difference in the mass of 100 moles each of sodium atoms and sodium ions is 5>48002 g. Compute the mass of an electron.
How many kilojoules a) are required to raise the temperature of 33.4 g CH3CH2OH(l) from 19.6 to 49.8 C b) must be removed from a 325 g sample of CH3(CH2)6CH3(l) to lower the samples temperature from 82.4 to 31.6
2C8H18(l) + 25O2(g) => 16CO2(g) + 18H2O(l) ?H = -11,200. kJ Standard enthalpies of formation, ?Hf: CO2(g), -393.5 kJ/mol; H2O(l), -285.8 kJ/mol Use the above data to calculate the standard enthalpy of formation of octane, C8H18(l).
say you removed an ice cube at -10 ordmc weighing 36 g from your freezer. now you place the ice cube in a 90 g sample
