The diagram shows two samples of gas enclosed in identical containers. each colored ball represents a gas particle. both samples have the same number of particles.
sample a
mass of each particle: 28 u
average particle speed: 980 m/s
sample b
mass of each particle: 44 u
average particle speed: 1,100 m/s
compare the average kinetic energies of the particles in each sample. which sample has the
higher temperature?
sample a
sample b
neither, both samples are the same.

Percent ionization for a weak acid (ha) is determined by the following formula: percent ionization=[ha] ionized[ha] initial×100%for strong acids, ionization is nearly complete (100%) at most concentrations. however, for weak acids, the percent ionization changes significantly with concentration. the more diluted the acid is, the greater percent ionization.a certain weak acid, ha, has a ka value of 9.4×10? 7.part acalculate the percent ionization of ha in a 0.10 m solution.part bcalculate the percent ionization of ha in a 0.010 m solution
