Homogeneous Reactions. At equilibrium, the rate of the forward and reverse reaction are equal, which is demonstrated by the arrows. The equilibrium constant, however, gives the ratio of the units (pressure or concentration) of the products to the reactants when the reaction is at equilibrium.
Explanation:
Element Abundance percent by weight Abundance parts per million by weight

Explanation:
Basically we were in toe to toe with the russians for space explorations like who's gonna get to space first or moon or do such explorations
...with the discovery and identification of the electron; and with the discovery of the first subatomic particle.
C'mon man, this is on the wiki page for J.J. Thomson, first paragraph.
Number of moles of HBr = 80.0 mL x(1L / 1000 mL) x (0.25 mol / L) = 0.02 mol
Number of moles of KOH = 40.0 mL x (1 L / 1000 mL) x (0.5 mol / L) = 0.02 mol
At this point all the acid is completely neutralized by base so; at the equivalence point pH of solution equal 7 (salt of strong acid and strong base KBr)
