A certain pure substance is a solid at 15°C. Sanjay heated a sample of the solid substance in a beaker using a Bunsen burner during science class. He and his partner recorded the temperature at one-minute intervals. Their data is recorded in the table below. What conclusion could be applied to the students' data? A) As the substance was heated and the temperature rose, a change of state occurred.
B) It took ten minutes for the solid substance to change state and melt into a liquid.
C) As the substance was heated, both the temperature and the kinetic energy increased.
D) The Bunsen burner did not supply enough thermal energy to melt the solid substance.

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
