A groud state hydrogen atom absorbs a photon of light having a wavelength of 94.96 nm. It then gives off a photon having a wavelength of 95nm.
Provide me with your exact logic used to get the answer. A mysterious material was purified from safflower oil (hint: full of fatty acids). Upon ozonolysis it gave the following compounds in their respective molar ratios.
Half-life equation for first-order reactions: (the 1/2 in t1/2 is a subscript) t1/2=0.693/k where t1/2 is the half-life in seconds (s) , and k is the rate constant in inverse seconds (s^-1).
upon catalytic hydrogenation unknown Z gives cyclooctane. Oxonolysis of Z followed by reduction with dimethyl sulfide, gives a three0carbon dialdehyde and a five-carbon dialdehyde. Draw the stucture of Z.
