Do colligative properties depend on the number of particles dissolved, the identity of the particles dissolved or both? Why?
What would the product/structure be if the reaction of methyl benzoate was a subsitution (add H and NO2 to it)?
What volume of base, in milliliters, is required to reach the equivalence point? (c) What is the pH at the equivalence point.
Suppose you want to heat air in your house with methane (CH4). Assume your house has 275 m2 of floor area and that ceiling is 2.50 m from the floor.
The solubility of zinc oxalate is 7.9 x 10-3 (exponential 3)M at 18 degrees celsius.Calculate its Ksp. Find the pure molar solubility of BaCrO4(Ksp=2.1x10(-10 Exponentially ) in a) pure water and b) 1.5 x10(-3 exponentially) M Na2CrO4.
The molar mass of HCl is 36.5 g/mol, and the average mass per HCl molecule is 36.5 amu. Use the fact that 1 amu = 1.6605 * 10-24g to calculate Avogadro's number.
