g As stated in the procedure, gas evolution may occur when the sodium bicarbonate (NaHCO3) solution is added in the experimental procedure. State the purpose of adding the sodium bicarbonate, provide a balanced chemical equation for the reaction that may occur, and identify the gas evolved.

What is the ph of a solution that has a hydrogen ion concentration of 1.0 * 10 -9 m?

Amixture initially contains a, b, and c in the following concentrations: [a] = 0.300 m , [b] = 1.05 m , and [c] = 0.550 m . the following reaction occurs and equilibrium is established: a+2b⇌c at equilibrium, [a] = 0.140 m and [c] = 0.710 m . calculate the value of the equilibrium constant, kc.

Which reason best explains why metals are malleable? a)because they have delocalized electrons b)because they have localized electrons c)because they have ionic bonds d)because they have rigid bonds
