When looking at an energy diagram, how do you determine what the rate-limiting step is? How do you determine what the energy of activation is for the rate determining step
Distillation is frequently used to isolate the nonvolatile organic solute from a solution containing an organic solvent. Explain how this would be accomplished using a simple distillation.
If the ultimate BOD of waste is 24mg/l and the BOD5 of that waste is 16mg/l, how much oxygen per liter would the waste consume in 7 days
The linear molecule FeH2 has been observed in the gas phase. Assume that the iron atom can potentially use s, p, and d orbitals to interact with the hydrogens
Can 1,2,3-tribromocyclohexane or 3-bromocyclohexene be formed as a side product if these experimental conditions are used? Explain please why?
A gas expands against a constant external pressure of 0.9 bar until its volume has increased from 6.8 L to 10.4 L. During this process it absorbs 770.0 J of heat from the surroundings. Calculate the energy change of the gas.
