A state government is considering construction of a flood control dike having a life span of 18 years. History indicates that a flood occurs every 6 years, on average, and causes $700,000 in damages on each occasion. If the stateuses a MARR of8% per year and expects every public works project to have a benefit-cost ratio of at least 1.0, what is the maximum investment (to the nearestwhole dollar) that will be allowed for the dike?

what are some examples of situations where recrystallization would not be suitable to purify an organic compound
A solution of only A is made that is initially 0.800 M. After the solution is allowed to reach equilibrium, it is determined that the concentration of B is 1.20 x 10^-4 M. Use this information to determine the equilibrium constant for the reaction..
