Given the segment header below of a transport protocol along with the following checksum definition that is computed and then stored before every segment is sent to a receiver: Treat the Source_port, Destination_port and Length fields as 8 bit numbers Add the Source port to the Destination port to obtain Result_1 Add Result_1 to the Length field to obtain Result_2 Take the 1’s complement of Result_2 and put the 8 bit value in the Checksum field
< 1 byte > <1 byte >
Source_port Destination_port
Length Checksum
Compute the value that will be put in the Checksum field for the segment below.
0011 0100 0110 1000
0001 0010

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;
