In Part 3, the initial concentration of H+ in Reaction Mixture 1 is 0.05M. What is the concentration of H+ after mixing?
"Pipette 10 mL of Reaction Mixture 1 into a 50 mL beaker. Pipette 1 mL of the KMnO4 into the Reaction Mixture, starting the stopwatch immediately."
A. 0.055MB. 0.05MC. 0.045MD. 6.00 × 10-2M
How many molecules of sucrose (table sugar), C12H22O11, dissolved in 450.0 g of water are needed to make a 1.30 m solution?
Consider the reaction: 2H3PO4=P2O5+3H20 Using the information below calculate the average rate of formation of P2O5 between 10.0 and 40.0 seconds.
with a solution in them connected by a liquid salt bridge junction filled with KNO3. In one solution you have a graphite electrode that is connected with a wire to a copper electrode in the second soution. The soution in contact with the graphite ..

It takes 54.0 J to raise the temperature of an 8.00 g piece of unknown metal from 13.0rm ^circ C to 24.5^circ{C}. What is the specific heat for the metal?
The printed label on a bottle of commercial vinegar states that the acetic acid concentration is 5%. (a) If the manufacturer had reported two significant figures int he concentration, what would the percentage range be so that all values would rou..
A cell measured by a student was found to be -0.461V against a Ag/AgCl reference electrode (0.222V). What is the potential when measured against SCE and NHE
Its titrated with NaOH. Being a triprotic and having 3 acid dissociation constants Ka1, Ka2, Ka3 one would expect to see three equivalence points. Why does it only show two equivalence points
Suppose that the calorimeter shown here was used to determine the energy change for an acid-base reaction. An acid/base reaction solution was made by combining 150 mL of 0.5 M HCl of 50 mL of 1.00 M NaOH, to make 200.0g of solution
