An alkaline battery produces energy according to the reaction below. Determine the limiting reactant if 25.0 g Zn and 62.5 g MnO2 are used. Determine the
theoretical yield in grams of Zn(OH)2. If 32.6 g of Zn(OH), are actually produced,
what is the percent yield?
Zn(s) + 2 MnO2(s) + H2O(l) → Zn(OH)2(s) + Mn, O3(s)

If you chip a tooth, most likely you will go to the dentist to have the missing material filled in. currently the material used to fill in teeth is a polymer that is flexible when put in, yet is hardened to the strength of a tooth after irradiation with blue light at a wavelength of 461 nm. what is the energy in joules for a photon of light at this wavelength?
