For the list of chemicals below, write complete, balanced equations for all possible reactions that would lead to an insoluble salt.
KNO3NaClAgNO3PbCl2K2SO4HNO3
Based on standard reduction potentials, would you expect copper metal to oxidize under standard conditions in the presence of oxygen and hydrogen ions
what is the pH of a solution obtained by adding 3.50g of HBr to 435mL of a 0.639M solution of HNO3?
Sleeping pills often contain barbital, which is weakly acidic (pKa = 8.00). For analysis of the barbital content of a sleeping pill, a titration is carried out with strong base. It takes 12.00 mL of 0.200 M base to reach the stoichiometric point.
In a certain process, 750. J of work is done on a system which gives off 195 J of heat. Calculate the total energy change (?U) for this process
In the early days of the periodic table, the 1870s, both silicon and tin were known elements, but germanium was unknown. Using these trends and the densities of silicon and tin that you just obtained, estimate the density of germanium?
Assuming that the limits of the visible spectrum are approximately 380-700nm, find the angular range of the first-order and second-order visible spectrum produced by a plane grating that has 900 grooves/mm with the incident source radiation normal..
Calculate the pH during the titration of 25.9 mL of 0.618 M ammonia NH3 with 0.205 M HCl after 11.5 mL of the acid have been added. Kb of ammonia = 1.8 x 10-5.
Determine At what temperature does C 6 H 6 boil when the external pressure = 470 torr?
