Tiny water drops in the air disperse the white light of the sun into a rainbow. What is the energy of a photon from the violet photon of the rainbow if it has a frequency of 7.23 times 10 to the sixth seconds.
Consider: 2 B5H9 (g) + 12 O2 (g) ? 5 B2O3 (g) + 9 H2O (g) ?H?reaction= - 8687 kJ. What is the enthalpy change when 0.2500 moles of B5H9 are combusted
NH3(Ammonia ) is widely used in many household cleaners and as a fertilizer. Calculate How much ammonia (in units of mol) is produced when 7.8 mol of H gas react with an excess of N gas.
