Atoms and molecules consist of electrons and nuclei. When no bonds exist between atoms, electrons are on discrete energy levels called orbitals: those levels where electrons reside at zero degree Kelvin are called ground states
When a solution of hydrogen peroxide (H2O2) is put on a cut, it bubbles, producing water and oxygen gas. If someone puts 0.54 mL of a 3.00% hydrogen peroxide solution on a cut, what is the volume in mL of oxygen produced?
If you fill the larger tank with oxygen to a pressure of 135 , to what pressure should you fill the acetylene tank to ensure that you run out of each gas at the same time? Assume ideal behavior for all gases.
