The specific heat of liquid bromine is 0.226J/g-K. How much heat (J) is required to raise the temperature of 10.0mL of brmine from 25.00D to 27.30C? The density of liquid bromine: 3.12g/mL
Calcium supplements commonly contain calcium ions in the form of calium carbonate (CaCO3). If one calcium supplement weights 600. mg, how many moles of calcium are contained in each pill
An advantage of the hydroboration reaction is that the rearrangement of the carbon skeleton does not occur. This lack of migration contrasts with results obtained upon the addition of hydrogen chloride to the double bond. Offer an explanation why.
When a particular metal is illuminated with photons, one electron is observed for each absorbed photon. What effect would decreasing the wavelength and number of photons, have on the electrons leaving the surface. Please show all work.
