The removal of giardia cysts from a soft, cold, low-turbidity water requires 20 mg/l of alum plus 0.1 mg/l of anionic polymer. (a) how many mg/l of natural alkalinity are consumed in the coagulation reaction? (b) how much (mg/l) carbon dioxide is released by this reaction? (c) what is the stoichiometric dosage of soda ash to react with the 20 mg/l of alum

2. determine the proper pump operating conditions and bit nozzle sizes for - chegg

answer:

// here is code in C++.

#include <bits/stdc++.h>

using namespace std;

//main function

int main()

{

  // variable

 int n;

 cout<<"enter a number:";

 // read the input

 cin>>n;

 // find the square root of the absolute value

 float square_root=sqrt(abs(n));

 // print the square_root

 cout<<"square root of "<<n<<" is: "<<square_root<<endl;

  return 0;

}

Explanation:

Read a number from user and assign it to "n".Then find its absolute value with abs() function.Then calculate the square root of the absolute value with sqrt() function.Print the square root of the number.

Output:

enter a number:-17

square root of -17 is: 4.12311
