In an Fe and Cr voltaic cell where the Fe is in Fe(NO3)2 and the Cr is in Cr(NO3)3; calculate the cell potential at 25 C if the initial concentration in the half cells are as follows [Cr 3+] = 2.45M and [Fe 2+] = .75 M
On a sheet of paper draw the molecule that fits the given description. From the structure you drew determine the correct IUPAC name.
A gas at 89.0°C occupies a volume of 0.67 L. At what Celsius temperature will the volume increase to 1.12 L
For such systems, it is often observed that the ratio of the vapor pressures of the pure species is nearly constant over a considerable temperature range. Let this ratio be r, and determine the range of values of A, expressed as a function of r, f..
calculate the ph of a solution that is prepared by mixing 2.16 grams of propanoic acid, CH3CH2COOH, and 0.56 grams of NaOH in enough water
A zero-order reaction has a constant rate of 1.90×10-4 . If after 40.0 seconds the concentration has dropped to 6.50×10-2 , what was the initial concentration?
A radioactive sample of 100g has been reduced to 1.56g in 85 years. How long is the half-life?
water skier is pulled by a net force of 180 N and has an acceleration of 2.4 m/s2. What is the mass of the skier?
A reaction of the form aA---->Products gives a plot of ln[A] vs time (in seconds) which is a straight line with a slope of -7.35e-3. Assuming [A]0=0.0100M,
where all compounds are assumed as covalent then determine which reaction must be endothermic and also explain your answer briefly?
Explain why butyl alcohol and isopropyl iodide are not formed in the reaction. Write a suitable mechanism for the cleavage of butyl isopropyl ether with HI at 100 degrees C to form exclusively isopropyl alcohol and 1- iodobutane.
A flask is charged with 0.140 mol of A and allowed to react to form B according to the following hypothetical gas-phase reaction. A(g)--> B(g)
