Calculate the cell potential of the following voltaic cell Zn / Zn2+ ( 1.0 x 10-8 M) // Cu2+ (1.0 x 10-6 M) / Cu a. + 1.16 V b. + 1.03 V c. + 1.14 V d. + 1.06 V e. + 1.10 V
A chemist was called to an abandoned aspirin factory to determine the contents of a badly corroded vat. Knowing that two salvage workers had become ill from breathing the fumes
600.0 mL of 0.240 M perchloric acid, HClO4(aq) was added to a high quality constant-pressure calorimeter containing 400.0 mL of 0.300 M KOH(aq). Both solutions have a density of 1.000 g mL-1 and a specific heat of 4.184 J g-1°C-1.
A sample that weighs 0.1586 grams contains only sodium chloride and potassium chloride was dissolved in water. It took 22.90 mL of 0.1000 AgNO3 to precipitate all of the chloride present.
The unbalanced equation for the reaction is... BrO3^-(aq) + Sb^3+ (aq) ---> Br^-(aq) + Sb^5+ (aq) Calculate the amount of antimony in the sample and it percentage in ore.
Oxalic acid dehydrate, H2C2O4. 2H2O (formula weight = 126.1 g/mol) is sometimes used to standardize NaOH solutions. How many grams of this acid will be required to titrate 45.0 mL of 0.18 M NaOH solution
Write a balanced equation for the neutralization of each of the following. Express your answer as a chemical equation. Identify all of the phases in your answer
Why can't diethyl ether form Hydrogen Bonds? (compared to 1-butanol). It has an Oxygen atom in the middle with lone pairs of electrons available. Is it because it's non-polar?
If the pH of a solution is 4.2 (at 25 degrees C) what is the hydronium and hydroxide ion concentrations, and the pOH of the solution
Draw a circuit diagram that has two resistors in series with a DC voltage source. If resistor one (R1) is 758 kohms and resistor two (R2) is 712 kohms, then what is the current flowing through the circuit if the voltage is 8.49 V?
Without doing detailed calculation, arrange the following 0.10 M aqueous solutions in order of increasing pH. Explain your ordering.
You are told to buy 5 packages of deli turkey, 3 loaves of bread and one jar of pickles. Our question is: how many sandwiches can we make?
Compound X is a miracle drug used to cure every sneeze and sniffle. It is very expensive though and customers complain it doesn't always work as well as it should.
