We add some solid silver chromate (Ag2CrO4, Ksp = 1.100x10-12) to a solution of 1.2202 M Li2CrO4. After equilibrium is achieved, what is the pAg (=-log[Ag+]) of this solution?
Predict the fraction of octahedral holes and tetrahedral holes that are filled by the various cations. octahedral holes filled with aluminum ions and tetrahedral holes filled with magnesium ions.
Commercial concentrated aqueous hydrogen peroxide is 30.% H2O2 by mass and has a density of 1.11 g/mL. What is the molarity of this solution
What mass of CaCl2 , when dissolved in 100.00 g of water, gives an expected freezing point of 5.0°C; CaCl2 is ionic? What mass of glucose would give the same result?
it was important that the flask be completly dry before the unknown liquid was added so that water present would not vaporize when the flask was heated.atypical single drop of liquid water has a volume of approximately 0.05ml
What is the vapor pressure, at 28 degrees C, of a solution made by mixing 80.0 g of C3H7SH and 120.0 g of CH3CN, if Raoult's Law is obeyed
briefly describe the theory behind IR spectroscopy and why it is a valuable technique to chemists.
High temperature and low pressure low temperature and high pressure none of the above unless a catalyst is present If it's endothermic, it's high temp and low pressure, but does having an exothermic reaction change that?
