Explain what would happen to the molar solubility of insoluble lead (II) chloride if sodium chloride were added to a saturated solution of lead (II) chloride. Comprise the relevant balanced chemical equilibrium
Carbonyl fluoride, COF2, is an important intermediate used in the production of fluorine-containing compounds. For instance, it is used to make the refrigerant carbon tetrafluoride, CF4 via the reaction
A flask contains 0.310 of liquid bromine, . Determine the number of bromine molecules present in the flask.
2.362 grams of an unknown hydrate are heated until all the water is removed. The anhydride reside weight 2.015 grams. Calculate the percentage of water in this hydrate
When they specifiy that "Measure out xx mg of the phosphonium chloride salt and the appropriate amount of aldehyde, equivalents with respect to the the phosphonium chloride)
A solution is initially 0.050M in acetate, CH3COO- (Kb = 5.6 x 10^-10). 10.0mL of 0.10 M HCl is added. a) Write the chemical equation for the nuetralization reaction that occurs.
Use the ideal gas equation of state to estimate the molar volume in m3/mol and the density of ari in kg/m3 at 40 C and a gauge pressure of 3.0 atm.
The student is presumed to observe the bacterium and make a drawing. Though, the student, having just learned about the Heisenberg uncertainty principle in physics class, criticizes that she cannot make the drawing. Claims that the uncertainty of ..
