If 50.0mL of 1.60M HCl was added to 50.0mL of 1.80M NaOH, calculate the molarity of the resulting NaCl solution. (Hint calculate the moles of NaCl made. The resulting solution has a volume of 100mL.) is there a solute in this solution in addition to the NaCl? if so, identify it and calculate its concentration.
Consider the six pz orbitals on carbon atoms (the pi system) of the benzene molecule (D6h symmetry). These may be treated as vector arrows pointing vertically above the plane of the six-membered ring.
What is the molarity of ZnCl2 that forms when 30.0 of zinc completely reacts with CuCl2 according to the following reaction? Assume a final volume of 285 mL . Zn+ CuCl2=ZnCl2+Cu.
which of the following is a property of an ionic compound?softmalleablelow boiling pointhigh melting
Illustrate this by showing the reaction of trans-p-anisalacetophenone with bromine and 2,4-dinitrophenylhydrazine to give the corresponding products
Consider a solution formed by mixing 48.0 mL of 0.100 M H2SO4, 36.0 mL of 0.100 M HOCl, 25.0 mL of 0.200 M NaOH, 2 mL of 0.100 M Ca(OH)2, and 10.0 mL of 0.150 M KOH. Calculate the pH of this solution.
Draw the structure of camphor and show which C-C bond must be broken to form the unwanted by-product

The thermal decomposition of phosphate into phosphorous and molecular hydrogen is a first order reaction : 4PH3(g) -----> P(g) + 6H2(g), The half life of the reaction is 35.0 s at 680*c
Titration of 664 mg of a pure organic carboxylic acid, H2A, showed a rapid change in pH at 40.00 mL and at 80.00 mL of 0.100 M NaOH titrant. When 40.00 mL of NaOH was added, the pH was 5.85, and at 60.00 mL of NaOH the pH was 8.08. What is the mol..
