A glucose solution contains 56.0 {rm g} of glucose ({rm{C}}_6 {rm{H}}_{12} {rm{O}}_6) in 440 {rm g} of water. Compute the freezing point and boiling point of the solution. (Assume a density of 1.00 {rm g}/{rm mL} for water.)
In the stock room you find a 12.0 M solution of HCl. How many mL of this solution should you dispense to make your diluted solution
Calculate the pH at the equivalence point for the titration of 0.100 M methylamine
compare the number of valence electrons in an atom of oxygen, O , with the number of valence electrons in an atom of selenium in the same period or group.
Substances A, B, and C can all act as oxidizing agents. In solution, a is green, B is yellow, and C is red. In the reactions in which they participate, they are reduced to A^-, B^-, and C^- ions, all of which are colorless.
In a particular redox reaction, NO is oxidized to NO3- and Fe3 is reduced to Fe2 . Complete and balance the equation for this reaction in acidic solution. Phases are optional. NO + Fe^3+ ----->NO3^- + Fe^2+
