The volume of a fixed amount of gas is doubled, and the absolute temperature is doubled. according to the ideal gas law, how has the pressure of the gas changed?

it has increased to two times its original value.
it has increased to four times its original value.
it has decreased to one-half its original value.
it has stayed 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
