Qualitative and Quantitative Equilibrium - PowerPoint

9 important questions on Qualitative and Quantitative Equilibrium - PowerPoint

What is Dynamic Equilibrium?


It is established when two reversible processes occur at the same rate, thus there is a constant ratio between reactant and product concentrations (Must be in a closed system)

What are aliphatic hydrocarbons?

Organic compounds w/ molecular structures tht are either straight, branched chains or rings of carbon-to-carbon bonds

What are aromatic hydrocarbons?

Organic compounds w/ rings of carbon bonded in alternating double-single-double structure tht switch to single-double-single

Ex: Benzene

How many bonds do alkanes have?

Alkanes have single bonds
C - C

Why does saturated NaCl in water have no net change (no visible change)? (3 reasons)

1. Closed vessel
2. Fixed temperature
3. For ea. Formula unit tht dissolves, there is 1 tht solidifies
(rate of dissolution = rate of crystalization)

What are conditions met for dissolving? Ex: saturated CO2 in H2O

1. Must have excess gas
2. Closed vessel
3. Fixed temperature


Explain how non-radioactive CH3I came to have some radioactive CH3I in it, even tho levels of liquid in both compartments did not change.


vapour of A goes to B:For ea. 1 particle of B going to liquid state, 1 particle goes to vapour state
  • thus, non-radioactive side becomes more radioactive
  • thus radioactive side becomes less radioactive (since some of non-reactive CH3I comes out of vapour state and goes to liquid state)
    • over time both A & B become equally radioactive
      • (no net chng in liquid vs vapour state)

What are ringed alkanes called?

Cycloalkanes
  • formula:
  • named "cyclo_____ane"
    • names are based on # of carbons it has!

What are the 3 steps in naming alkanes?

  1. Find the longest chain
  2. Determine the # and types of branches
  3. Designate the position of the branch by stating # of the carbon in longest chain it is attached to
