Question: Atoms of the never-discovered element fictitium (Fi) have energy states as shown in Fig.
a. What would be the energies of photons emitted after a vapor of Fi is bombarded with 3.7eV electrons?
b. What would be the energies of photons emitted after a vapor of Fi is bombarded with 3.7eV photons?
c. Assume that Fi is in its ground state. What is the longestwavelength photon that this atom can absorb?
d. Fi has a nucleus with a radius of 4fm. Use the Heisenberg uncertainty principle to estimate the kinetic energy of a proton confined within this region.

In the balanced molecular equation for the neutralization reaction between phosphoric acid and potassium hydroxide, the products are: a. 3H2O b. K3PO4 + 3H2O c. KPO4 + H3OH d. K+(aq) + PO43-(aq) + 3H+ + 3OH-
What I don't understand is how they got it. I know that tetraphosphorus hexoxide is P4O6 and water is H2O. What I don't understand it how it becomes 4H3PO3.
