What is the chemical equation that shows how a H3PO4 / NaH2PO4 buffer will react to the addition of a strong acid and a chemical equation that shows what happens with the addition of a strong base?
The molecular formula is C4H10N2. •There are no ? bonds in the structure. •The compound has no net dipole moment. •The compound exhibits very strong hydrogen bonding.
Chlorine is more reactive than bromine. Bromine can be prepared by adding chlorine to an aqueous solution of sodium bromide. The reaction is represented by the equation 2 NaBr(aq) + Cl2(g) = Br2(l) + 2 NaCl(aq)
