A gaseous sample of this element is bombarded by photons of various energies (in these same units). Match each photon to the result of its absorption (or lack thereof) by an n=1 electron.
A sample of zinc weighing 2.077 g is dissolved in 2.00 M HCl. What (minimum) volume of HCl is required to dissolve the Zn? (Zn dissolves in HCl to form Zn2+
During the late 1800's, hard rock miners replaced candles with carbide lamps for work in mine shafts. The lamps worked by dripping water onto calcium carbide that generated acetylene gas (H2C2) that was burned
