(note: the databases you will evaluate come from student groups in another class responding to the hokie resort problem. this problem also is provided for your review.)
to achieve this you decide to do the following:
review the hokie resort situation description and the er diagrams for the two operational databases.
write the three most important questions that management must answer to achieve a competitive advantage in the hotel market. submit the questions and a brief (1-2 pages) explanation/justification of why these are the most important questions. (10 points)

Write a function balancechemical to balance chemical reactions by solving a linear set of equations. the inputs arguments are: reagents: symbols of reagents in string row array products: symbols of products in string row array elements: elements in the reaction in string row array elcmpreag: elemental composition of reactants in two dimensional numeric array elcmpprdcts: elemental composition of prducts in two dimensional numeric array hint: the first part of the problem is setting up the set of linear equations that should be solve. the second part of the problem is to find the integers from the solution. one way to do this is to mulitiply the rational basis for the nullspace by increasing larger integers until both the left-and right-side integers exist. for example, for the reaction that involves reacting with to produce and : reagents=["ch4", "o2"]; products =["co2", "h2o"]; elements =["c","h", "o"] elcmpreag=[1,4,0;
