The volume of a sphere is given by the equation =4/3 ^3,V=43πr3, where r is the radius. Calculate the volume of a sphere with a radius of 437 pm 437 pm in cubic meters.
You collect a distillate sample which has a refractive index of 1.391. Assuming that the refractive index of the hexane + toluene mixture varies linearly with mole fraction, what is the mole fraction of hexane in your sample?
The reaction will be spontaneous at high temperatures because increasing the temperature of a system with a negative change in S eventually results in a positive change in G.
1.00 mL of .500 M Ag+ is added to this solution and the resultant AgCl quantitatively precipitated. Basd on the Ksp expression, calculate the concentration of the Cl- that remains in solution
Calculate the percent yield of benzophenone to triphenylmethyl reaction. started with 4.09g of benzophenone and ended up with .682g triphenylmethyl can anyone help me convert these into moles and calculate the yield
Consider the voltaic cell below, which is symmetric except for the fact that [Cu2+] is 1.0 M on the left side and 0.01 M on the right. Which electrode is +, and what is Ecell?
If the hydroxyl group has been inverted during the conversion of (1S)-borneol to the product why do we get (1S)-isoborneol in its place of (1R)-isoborneol. Explain how many asymmetric C-atoms are present and which one is 1S
Will the concentration of Ni2+ increase or decrease as the cell operatres? c. What is the initial concentration of Ag+ in the cell?
Calculate mass of the dye per liter Kool Aid solution C in units of grams/L, i got a molecular weight of the dye as 496.42g/mol a concentration of the dye as 1.26x10^-14 mol/L and a mass of Kool Aid of 0.566g
In a particular redox reaction, NO is oxidized to NO3- and Fe3 is reduced to Fe2 . Complete and balance the equation for this reaction in acidic solution. Phases are optional. NO + Fe^3+ ----->NO3^- + Fe^2+
Estimate the mass of water that must evaporate from the skin to cool the body by 0.50^circ C. Assume a body mass of 85 kg and assume that the specific heat capacity of the body is 4.0 {rm{J}}/{rm{g}}; cdot ;^circ {rm{C}}.
