1. What additional control(s) could have been implemented to assure the imposter establishing an identity with tech support would have been thwarted? 2. Humor about the emojis aside, Star Fraud is made up of mostly North American teenagers. What about teenagers make them a more likely candidate for computer fraud, compared to traditional financial reporting fraud that is usually perpetrated by older, c-suite executives? 3. What control allowed for the computer systems to be rebuilt? What do you think about Bill Hornbuckle's decision to shut all the servers down and restart versus paying the ransom? What decision would you have made?

Which of the following statements are true and which are false. true false The equilibrium constant depends on the initial concentrations. true false In general, at a given temperature, the reaction quotient (Q) is a constant. true false 1 mol of H2O(g) and 1 mol of CO(g) are placed in a vessel and 1 mol of H2(g) and 1 mol of CO2(g) are placed in another of equal volume. At equilibrium, at 350°C, the amounts of H2(g) in the two vessels are equivalent. true false At equilibrium, individual molecules may be subject to rapid chemical transformations. true false At equilibrium, the overall composition of the reaction mixture is changing slowly. true false Amounts of all reactants and products corresponding to an exact equilibrium composition for this reaction are sealed in a vessel. The CO placed in the vessel is labelled with 14C. After an indefinite period of time 14C may be found in both CO and CO2 molecules.
