Suppose a tank is filled with A2(g) so that initial pressure is 0.8688 atm at temperature of 298K. Some of the A2(g) dissociates and when the system reaches equlibrium the total pressure in the tank is 1.275 atm. Calcula ...
Suppose that you take .5000 gram of Na2CO3 and titrate it with .115M HCL solution. What is the equivalence point volume expected for the complete titration? (Formula weights Na2CO3 = 105.99g/mol and HCL = 36.46g/mol)
A 1.000 g sample of copper metal is heated in a crucible and after 15 minutes themass of the crucible contents is 1.111 g. Calculate the mass of copper (II) oxide that was produced.
A chemist must dilute 37.4 mL of 8.08 μM aqueous mercury(I) chloride (Hg2Cl2) solution until the concentration falls to 2.00 μM. He'll do this by adding distilled water to the solution until it reaches a certain final vo ...
