Describe 3 uses of rhodium as a catalyst (written description and the balanced chemical equation) for its use in
1)three way catalytic converters on cars
2) the manufacture of acetic acid by catalytic carbonylation of methanol, called the Monsanto process
3) its use for the plating of jewelry and other things because it does not oxidize at all in the air and remains shiny.
The addition of a sodium flouride solution to one of lead nitrate results in a net ionic equation of PB 2+ (aq) + 2 Fe- (aq) yielding PbF2 (s). If 25.0 ml of 0.200 M NaF solution are mixed with 10.0 ml of 0.150 M Pb(NO3)2 solution, how many grams ..
A beaker with 185 mL of an acetic acid buffer with a pH of 5.00 is sitting on a benchtop. The total molarity of acid and conjugate base in this buffer is 0.100 M. A student adds 6.70 mL of a 0.440 M HCl solution to the beaker.
