How to transform a primary amine into corresponding alkyl halide?
A solution is made by mixing 15.5 g of NaOH and 73.0 mL of 0.150 M HNO3. Calculate the concentration of OH- ion remaining in solution.
The sample is diluted with 72.178 g of water. A 14.024 g aliquot of this solution is then titrated with 0.1097 M HCl. It required 29.55 mL of the HCl solution to reach the methyl red endpoint. Calculate the weight percent NH3 in the aqueous waste.

calculate the freezing point and boiling point of an aqueous solution that is .040 molality in na3po4. assume that the
The temperature of the acid solution increases from 24.2 oC to 29.9 oC. Calculate deltaH for the reaction that occurred.
Compute the packing efficiency for an fcc lattice, keeping in mind that the close-packing direction is along the body diagonal, yielding a row of atoms along a face diagonal (i.e., the face diagonal = 4r). How does this compare to primitive cubic ..

Mg3N2(s) + H2O(l) → Mg(OH)2(s) + NH3(g) If this process is 82% efficient, what mass of ammonia can be prepared from 22.0 kg magnesium nitride.
The value of the euro was recently $1.38 u.s. and the price of 1 liter of gasoline in france is 1.35 euro
Suppose there are two known compounds containing the generic elements X and Y. You have a 1.00-g sample of each compound. One sample contains 0.32 g of X and the other contains 0.41 g of X. Identify plausible sets of formulas for these two compoun..
We did an experiment in class today heating a metal object over a bunsen burner, submerging it in water and recording the temperature to see what the heat flow was.
