The min. energy needed to break a C-Br bond is 288000mol^-1. If one has access to laser with 3 output wavelengths 266,1065,800nm, which wavelength(s) can be used to break that bond? I keep getting 417nm for the wavelength (which is none of the outputs) but the answer is 266nm....
A Norman window has the shape of a rectangle surmounted by a semicircle. (Thus, the diameter of the semicircle is equal to the width of the rectangle.) If the perimeter of the window is 30 ft, find the dimensions of the window so that the greatest possible amount of light is ...
A student was given 100mL of HCL solution in a 250mL beaker and told that the HCL was 0.11M. The student was also given phenolphthalein indicator and 250 ML of 0.1234 M NaOH. The student first filled a buret with NaOH solution. The student then placed an appropriate volume of ...
