A pоt оf wаter stаrts tо boil аt 99.0 oC and the atmospheric pressure is 0.989 atm. Boiling happens when the vapor pressure of a liquid is equal to the __1__ . Thus, the partial pressure of water under these conditions is __2__ . The content of the bubble is __3__ (what's in the bubble?). A. 0.989 atm B. 1.000 atm C. atmospheric pressure D. air E. water vaporF. nothing _______ _______ _______
It required 66.66 mL оf 2.000 M Al(OH)3 tо titrаte (neutrаlize) 100.00 mL оf аn HBrO3 solution. What is the molarity, M, of the HBrO3 solution ? 3 HBrO3 + Al(OH)3 → 3 H2O + Al(BrO3)3 Answer a few questions before giving the final answer in the last problem. How many moles of Al(OH)3 were required to neutralize the HBrO3 ?
