Give some values of pressure and temperature at which you are sure that the substance called zinc exists in an equilibrium state as a) solid and b) vapor. Explain how you go the results
This was allowed to react under reflux for an hour and then the products seperated. I wrote out a mechanism before lab and ended up predicting 4-chlorobenzoic acid and 4-chlorophenol as my final products.
Key by key on calculator how would I solve for x in 0.2=(0.5)^(x/14.2)? -Original question that brought me to that point-"The half-reaction of 32P is 14.2 days
