Write the dissociation equation for, and give the proper concentrations for a 0.25M K2SO4 solution

concentration of  = 0.50 M

concentration of   = 0.25 M

Explanation:

The dissociation equation of is:

According to stoichiometry:

1 mole of gives 2 moles of

Thus 0.25 moles of gives = moles of

Similarly,

1 mole of gives = 1 mole of

Thus 0.25 moles of gives = moles of

Thus the concentration of and are 0.50 M and 0.25 M respectively.

a 20-cm-long, cylindrical graphite (pure carbon) rod is inserted into an oxidizing atmosphere at 1145 k and 1.013 x 105 pa pressure. the oxidizing process is limited by the diffu- sion of oxygen counterflow to the carbon monoxide that is formed on the cylindrical surface.
