Aqueous silver ion reacts with aqueous chloride ion to form a white precipitate of silver chloride: When 10.0 mL of 1.00 M AgNO_3 solution is added to 10.0 mL of 1.00 M NaCl solution at 25.0 degree C in a coffee-cup calorimeter, a precipitate of AgCl forms and the temperature of the aqueous mixture increases to 32.6 degree C. Assuming that the specific heat of the aqueous mixture is 4.18 J/(g middot degree C), that the density of the mixture is 1.00 g/mL, and that the calorimeter itself absorbs a negligible amount of heat, calculate delta H in kilojoules/mol AgCl for the reaction. 635 kJ/mol -635 kJ/mol 63.5 kJ/mol -63.5 kJ/mol -31.7 kJ/mol Calculate the wavelength of yellow light of frequency 5.20 times 10^14 Hz. 520 nm 1150 nm 173 nm 56 nm 576 nm

Explanation / Answer

23. We know

Wavelength=speed of light/frequency

Wavelength=3×108/5.24×1014

Wavelength=576nm
