affected when nuclear fusion occurs inside a

energy inside a star and the amount used to
power a city
С
an explanation of the elements that cause
stars to heat and collapse during nuclear
fusion
D
a series of events that triggered the creation
of our solar system millions of years ago

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
