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.

What are the five layers in the internet protocol stack? What are the principal responsibilities of each of these lay?
mariarad [96]

Solution:

The five Layers in Internet protocol stack are:

1.Application Layer  

2.Transport Layer  

3.Network Layer  

4.Link Layer  

5.Physical Layer  

The principal responsibilities of these layers are as follows:

1.Application Layer •Applications with appropriate requirement for user.  

•It is reserved for network applications and their application protocols such as HTTP, SMTP, and FTP etc.  

•Its protocol uses transport layer protocols for establishing host-to-host connection.  

2.Transport Layer  

•It is responsible for End-to-Communication  

•Transport layer transports messages from application layer between client and server of application  

•It uses two protocol for transporting messages: TCP and UDP.TCP provides reliable connection oriented services, while UDP provides connectionless service  

3.Network Layer  

•Network Layer moves packets from one host to destination.

•It has two principal component:IP protocol:-It defines the datagrams and decide how the end system and router will work Routing protocols: these protocols decide the routing path between source and destination. 4.Link Layer  

•It is responsible for link-level communication  

•Link layer receives the data gram from network layer at each node and delivers it to next node, the next node passes the datagram to network layer.so This layer moves entire frames from one network element to adjacent one.

•The service provided by link layer is protocol dependent

5.Physical Layer  

•It provides Physical media

•At each node, it moves individual bits of frames to next node.

Create a Card class that represents a playing card. It should have an int instance variable named rank and a char variable named
Helen [10]

Answer:

Explanation:

The following code is written in Java. It creates the Card class and then uses it to create a full house and print out the rank and suit of every card in that hand.

class Card {

   int rank;

   char suit;

   public Card(int rank, char suit) {

       this.rank = rank;

       this.suit = suit;

   }

   public int getRank() {

       return rank;

   }

   public char getSuit() {

       return suit;

   }

}

class CardTester {

   public static void main(String[] args) {

       Card card1 = new Card(3, '♥');

       Card card2 = new Card(3, '♠');

       Card card3 = new Card(3, '♦');

       Card card4 = new Card(2, '♦');

       Card card5 = new Card(2, '♣');

       System.out.println("Card 1: " + card1.getRank() + " of " + card1.getSuit());

       System.out.println("Card 2: " + card2.getRank() + " of " + card2.getSuit());

       System.out.println("Card 3: " + card3.getRank() + " of " + card3.getSuit());

       System.out.println("Card 4: " + card4.getRank() + " of " + card4.getSuit());

       System.out.println("Card 5: " + card5.getRank() + " of " + card5.getSuit());

   }

You are given a class named Clock that has three instance variables: One of type int called hours, another of type boolean calle
Ivahew [28]

Answer:

Clock (int hours, boolean isTicking, int diff) // constructor clock

{

this.hours = hours;

// set the instance variable hours

this.isTicking = isTicking;

// set the boolean variable isTicking

this.diff =diff;

//set the instance variable diff

}

Explanation:

Here we declared a constructor clock which has 3 parameter hours,boolean isTicking,and diff.

The int hours, diff is of int type and isTicking is of boolean type. In this constructor, we set the instance variables values by using this keyword.
