Calculate the cell potential for the following reaction as written at 53C, given that [Zn2+]= .841M and [Fe2+]= .0160M. Standard reduction potentials are Zn(s)= -.76, Fe2+(aq)= +.771, Zn2+(aq)= -.76, Fe(s)= -.04
the following set of data was obtained by the method of initial rates for the reaction: 2 HgCl(aq) +C2O42-(aq)-> 2Cl-(aq) + 2 CO2(g) + Hg2Cl2(s) what is te rate law for the reaction
Research the number of electrons that can fit into energy levels higher than the third level. Why does that explain why there is a space in the lower periods of the periodic table?
A fossil fuel containing 84% C, 15% H and 1%S is burned with 20% excess air in a boiler. The stack gases are at 150 C. a) What is the concentration (ppm) of SO3 in the stack if equilibrium is established according to
Write the expression for the reaction rate in terms of d[NOCl]. c. The concentration of NOCl drops from 0.580 M to 0.238 M in 8.00 min. Calculate the average rate of reaction over this time interval.
A gas expands and does pv work on its surroundings equal to 347 J. At the same time, it absorbs 127J of heat from the surroundings, what is the change in energy of the gas.
Clearly explain, using calculations as necessary, how you would obtain the 5 mL of 1.5M sodium hydroxide that you need
Use the Henderson-Hasselbach equation to calculate the pH of an acetate buffer in which the acetate concentration [CH3COO-] is three times greater than the acetic acid [CH3COOH] with a pKa of 4.76.
Suppose your thermometer read consistently 1.0 o C lowered throughout both parts in the colligative properties lab. What effect would that have on your experimental value for the molar mass of your unknown solute?
In many cases, patients require medication to be infused on a continual base. Paramedics will receive orders to administer a certain number of units (usually milligrams or micrograms) of a medication per minute to a patient through an IV. Known as..
