In your class, many students are friends. let’s assume that two students sharing a friend must be friends themselves; in other words, if students 0 and 1 are friends and students 1 and 2 are friends, then students 0 and 2 must be friends. using this rule, we can partition the students into circles of friends. to do this, implement a function networks() that takes two input arguments. the first is the number n of students in the class. we assume students are identified using integers 0 through n 1. the second input argument is a list of tuple objects that define friends. for example, tuple (0, 2) defines students 0 and 2 as friends. function networks() should print the partition of students into circles of friends as illustrated: > > > networks(5, [(0, 1), (1, 2), (3, 4)]) social network 0 is {0, 1, 2

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;
