Interstate 285 around atlanta is 63.98 mi and is about 80. ft across both directions of traffic. if there are 2.5 inches of snow (kf = 1.86 °c/m, density = 0.150 g/cm3) accumulated on the interstate, how many metric tons of cacl2 are required to alter the freezing point from 32 degrees f to 21 degreesf? ( 1 mi = 1609.34 m, 2.54 cm = 1 in, 12 in = 1 ft, 1000 kg = 1 metric ton)

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
