Using the standard reduction potentials given in your text book, calculate the Standard Cell EMF at 298 K for each of the following reactions.
(A) F2 (g) + 2 Br- (aq) → 2F - (aq) + Br2 (l)
(B) 3 Mn2+ (aq) + 2 Al (s) → 3 Mn (s) + 2Al3+ (aq)
(C) O2 (g) + 2 H2O (l) + 4 Ag (s) → 4 OH- (aq) + 4 Ag+ (aq)
Draw a logarithmic concentration diagram showing the relationship between [CO2] and [Ch4] as a function of pE for pH=7 and [CO2] +
a solution of malonic acid h2c3h2o4 was standarized by titration with 0.1000m naoh. if 20.76ml of the naoh solution
Question- Calculate the relative amounts of H2PO4- and HPO4(2-) that should be combined to produce a phosphate buffer at pH7. (pKa= 6.86 and molarity= 0.1 M)
Calculate the number of grams of aluminum required to prepare 500.0g of chromium metal.
Zinc(II) sulfide reacts with oxygen according to the reaction- How many moles of oxygen will be required to react with ZnS
how much heat is released at constant pressure when 50.0 g of nis reacts with excess o2 according to the reaction
The initial solution pH depend on both the Ka and the concentration of the weak acid, so measuring the initial pH very accurately may be sufficient to determine both these unknowns.
a piece of metal with a mass of 151 g is placed in a 50 ml graduated cylinder. the water level rises from 20. ml to 35
Manganese makes up 1.3*1-^-4 percent by mass of the elements found in the healthy male body of a certain mammal. If 0.11 g of manganese if sound, how much does the average male body weigh
Determine the dynamic responses for a+10 percent change in inlet flow rate in place of the original input change for one or more of Examples.
A 0.468 mol of O2 gas has a volume of 11.5 L at a certain temperature and pressure. If all this O2 were converted to ozone (O3) at the same temperature and pressure, what would be the volume of the ozone. 3O2?2O3
if a sample of 2.63 L of neon is collected at 730 torr and 26 degrees C, what volume will the gas occupy at 1.10 atm and 10 degrees C?
