For each reaction, identify the acid-base conjugate pairs. Then rank all reacionts in order of increasing tendency for the reaction to go to completion (to the right). (Hint: reactions runs toward weaker acid and base).
a) CH3COO- + HCN <--> CH3COOH + CN^-
b) CH3OH + Br^- <--> CH3O^- + HBr
c) HSO4^- + NH3 <--> SO4^2- + NH4^+
d) HClO4 + CH3NH2 <--> ClO4^- + CH3NH3^+
Calculate the percent by mass of calcium carbonate in the rock, assuming that it is the only substance reacting with the HCl solution.
provide reaction mechanisms for the formation of each of these byproducts and specify whether the mechanisms you write are SN1, SN2, E1, E2, or none of these. explain why you would expect bisulfate to be a good leaving group for substitution or eli..
The Cl^- concentration in the water analysis given has been questioned. What concentration of Cl^- (mg/L) would make the cations and anions balance?
Hydrogen sulfide () is a common and troublesome pollutant in industrial wastewaters. One way to remove is to treat the water with chlorine, in which case the following reaction occurs:
A water desalination plant is set up near a salt marsh containing water that is 0.10 M NaCl. Calculate the minimum pressure that must be applied at 17°C to purify the water by reverse osmosis.
Which of the following is NOT true about the thermodynamic standard state?
Calculate the % yield of Al2(SO4) from the reaction: 2Al(OH)3(s) + 3H2SO4(aq) -> Al2(SO4)3(s) + 6H2O(l) given that 205 g of Al(OH)3 react with 751 g of H2SO4 to yield 252 g Al2(SO4)3.
Aerosol cans have a label that warns the user not to use them above a certain temperature and not to dispose of them by incineration. Even an empty can contains residual gaseous propellant.
