Computers and Technology
1 answer:
juin [17]3 years ago
3 0

Answer:

A. The mixture contains compounds with similar polarities but different solubilities.

Explanation:

Liquid – Liquid (LLE) extraction is a process for the isolation of compounds or metal complexes, also known as solvent extraction and partitioning, based on their relative solubility in two distinct liquids, generally water- (polar) liquids and an organic solvent (non-polar). Net transition from a liquid to a liquid process of one or more species, normally from aqueous to organic.

imagine that you wanted to write a program that asks the user to enter in 5 grade values. the user may or may not enter valid gr
Aloiza [94]

In a computer program, loops are used to perform repetitive operations until a condition is met.

The nested loop structure to use in this case is: <em>A "while" loop inside of a "for" loop</em>

<u>The outer loop</u>

First, you must iterate through each student.

This can be done using a for loop or a while loop.

However, it is faster to implement this kind of iteration on a for loop, than a while loop

So, the algorithm of the outer loop would look like the following:

<em>for student = 1 to 5 step 1</em>

<em />

<u />

<u>The inner loop</u>

Next, you must get input for the 5 grades for each student

After getting input for the grade of each student, a loop would be used to test if the input is valid.

The loop would be repeated until the user enters a valid input.

This can only be done using a while loop.

So, the algorithm of the inner loop would look like the following:

<em>input grade</em>

<em>while grade is invalid:</em>

<em>     input grade</em>

<em />

<em />

<em />

Hence, the nested loop structure to use is:

<em>A "while" loop inside of a "for" loop</em>

<em />

<em />

For this assignment, you will write a program that calculates gross and net revenue for a movie theater. Consider the following
Marrrta [24]

Answer:

// This program is written in C++

// Comments are used for explanatory purpose

#include<iostream>

using namespace std;

int main()

{

// Declare variables

int childticket, adultticket, childprice, adultprice;

double total, net, distributor;

string movie;

// Prompt user for name of movie

cout<<"Movie Name; ";

// Accept input for movie name

cin>>movie;

// Prompt user and accept input for price of adult tickets

cout<<"Adult Ticket Price: $";

cin>>adultprice;

// Prompt user and accept input for price of child tickets

cout<<"Child Ticket Price: $";

cin>>childprice;

// Prompt user and accept input for number of sold adult tickets

cout<<"Adult Ticket Sold: ";

cin>>adultticket;

// Prompt user and accept input for number of child tickets sold

cout<<"Child Ticket Sold: ";

cin>>childticket;

// Calculate total

total = childticket * childprice + adultticket * adultprice;

// Calculate distributor's payment

distributor = 0.25 * total;

// Calculate net box pay

net = 0.75 * total;

// Display and format results

cout<<"Gross Box Office Revenue: $";

printf("%.2f",total);

cout<<"\n Amount Paid to Distributor: -$";

printf("%.2f", distributor);

cout<<"\nNet Box Office Revenue: $";

printf("%.2f",net);

return 0;

}

Write a set of nested loops that display 10 rows of # characters. There should be 15 # characters in each row.
Andrews [41]

Answer:

Following are the code to this question:

public class M//defining class M

{

public static void main(String[] as)//defining main method

{

    int i,j;//defining integer variable

for (i= 1; i <=10; i++)//defining for loop for print column    

{

for (j = 1; j<=15; j++)//defining for loop for print rows

{

System.out.print("#");//print # value

}

System.out.println();//print space

}

}

}

Output:

###############

###############

###############

###############

###############

###############

###############

###############

###############

###############

Explanation:

The code defines a class "M" and the main method is defined within a class and two integer variables I and j" are defined within the primary procedure, while the next step defines two for a loop.  

In the first loop, the column value is printed, and a further loop that prints the row value is declared inside the loop.

Write a flowchart and C code for a program that does the following: Uses a do...while loop. Prints the numbers from 1 to 10 with
emmasim [6.3K]

Answer:

create the integer variable and initialize it to one, with the do statement, increment the variable by one and print it, then the while statement checks if the variable is less than or equal to 10.

#include <iostream>

using namespace std;

int main(){

   int i = 1;

   do {

       cout<< i << "\n";

       i++;

   }

   while (i <= 10);

}

Explanation:

The C++ source code initializes the integer variable i to one and increments and print the value if the value is less than or equal to ten. The do-while statement executes a block of code before the condition is implemented.
