A series of vertical curves connect a 3% upgrade, a 2% downgrade, and another 3% upgrade moving west to east. These curves are designed such that they connect directly to one another (i.e., the PVT of the first curve is the PVC of the second curve). If the design speed of the alignment is 60 mi/h, what is the elevation difference between the two road segments (i.e., the vertical difference between the PVC of the first curve and the PVT...

You should use NO MORE THAN 100 mL 0.25 M NH4OH, 4 g Ca(NO3)2· 4H2O, and/or 3 g (NH4)2HPO4. NOTE: This is not a stoichiometric recipe. Part of the grading for this lab will be based on your ability to determine appropriate quantities of each reactant. Clearly show the actual amount of each reactant you intend to use. Determine the mass or volume of each reactant in the proper stoichiometric ratio, to synthesize and analyze a sample of calcium hydroxyapatite....
