You add an excess of solid MX in 250 g of water. You measure the freezing point and find it to be 20.028oC. What is the Ksp of the solid?
Answer to relevant QuestionsA solid consists of a mixture of NaNO3 and Mg(NO3)2. When 6.50 g of this solid is dissolved in 50.0 g of water, the freezing point is lowered by 5.40oC. What is the composition of the solid (by mass)? Assume ideal behavior. What mass of barium is produced when molten BaCl2 is electrolyzed by a current of 2.50 × 105 A for 6.00 h? What is the valence electron configuration for Group 4A elements? Group 4A contains two of the most important elements on earth. What are they, and why are they so important? How does metallic character change as one goes ...The compound Pb3O4 (red lead) contains a mixture of lead(II) and lead(IV) oxidation states. What is the mole ratio of lead(II) to lead(IV) in Pb3O4? Use bond energies (Table 13.6) to show that the pre-ferred products for the decomposition of N2O3 are NO2 and NO rather than O2 and N2O. (The N–O single-bond energy is 201 kJ/ mol.) (Hint: Consider the reaction ...
