Answer:

Compound can be represented as a molecular formula,empirical formula, structural formula,ball and stick model, space filling model.

Explanation:

Compounds can be represented as a chemical formula and a molecular model.

A chemical formula shows the number of atoms present in a compound. Whereas, the molecular model shows the geometry of a compound.

The chemical formula can be further divided into 3 types:

1)molecular formula: indicates the actual number of atoms in a compound.

2)empirical formula: indicates the relative number of atoms present in a compound.

3)structural formula: is illustrated in the forms of lines which actually shows the bond(such as covalent bond) and also shows how atoms are connected to each other in a molecule.

Molecular model is preferably a better way to represent a molecule. It is categorised into the following:

1)a ball and stick model: its a three dimensional representation of a compound. The atom(s) in a compound is represented by ball while, their chemical bonds are shown by sticks.

2)A space filling model: its a three dimensional structure,it represents the size and shape of the whole molecule,showing relatively how much space each atom in a molecule occupies.

Answer:

structural formula, space-filling model, molecular formula, empirical formula and ball and stick model.

Explanation:

Chemical compounds are resultants of chemical elements in a reaction. There are several ways of represent a compound, they are;

Structural formula represents chemical compounds in a two dimensional diagram, showing the bonding of the various elements.

Empirical formula gives the relative number of atoms in the compound, while molecular formula shows the actual number of atoms. Space filling, and ball and stick models are three dimensional diagrams describing the relationship between elements represented as balls and bonds as sticks ( for ball and stick model), and the space occupied by individual elements in the compound (space filling).

Answer:

lean media

Explanation:

Dr. Thomas uses email as a medium of lean media to convey messages.

Lean media may be defined as the source of conveying messages that are short or of lean capacity. It is meant for instant messages and message and information that is not considered to be of out most importance. Whereas a rich media is a video chat or face to face communication.

Dr. Thomas send emails to her patients to follow up with them and also encourages her patients to call her for appointments or any questions. She uses email as a source of lean media for this communication.

Develop a C program that calculates the final score and the average score for a student from his/her (1)class participation, (2)
Ghella [55]

Answer:

#include <iomanip>

#include<iostream>

using namespace std;

int main(){

char name[100];

float classp, test, assgn, exam, prctscore,ave;

cout<<"Student Name: ";

cin.getline(name,100);

cout<<"Class Participation: "; cin>>classp;

while(classp <0 || classp > 100){  cout<<"Class Participation: "; cin>>classp; }

cout<<"Test: "; cin>>test;

while(test <0 || test > 100){  cout<<"Test: "; cin>>test; }

cout<<"Assignment: "; cin>>assgn;

while(assgn <0 || assgn > 100){  cout<<"Assignment: "; cin>>assgn; }

cout<<"Examination: "; cin>>exam;

while(exam <0 || exam > 100){  cout<<"Examination: "; cin>>exam; }

cout<<"Practice Score: "; cin>>prctscore;

while(prctscore <0 || prctscore > 100){  cout<<"Practice Score: "; cin>>prctscore; }

ave = (int)(classp + test + assgn + exam + prctscore)/5;

cout <<setprecision(1)<<fixed<<"The average score is "<<ave;  

return 0;}

Explanation:

The required parameters such as cin, cout, etc. implies that the program is to be written in C++ (not C).

So, I answered the program using C++.

Line by line explanation is as follows;

This declares name as character of maximum size of 100 characters

char name[100];

This declares the grading items as float

float classp, test, assgn, exam, prctscore,ave;

This prompts the user for student name

cout<<"Student Name: ";

This gets the student name using getline

cin.getline(name,100);

This prompts the user for class participation. The corresponding while loop ensures that the score s between 0 and 100 (inclusive)

<em> cout<<"Class Participation: "; cin>>classp; </em>

<em> while(classp <0 || classp > 100){  cout<<"Class Participation: "; cin>>classp; } </em>

This prompts the user for test. The corresponding while loop ensures that the score s between 0 and 100 (inclusive)

<em> cout<<"Test: "; cin>>test; </em>

<em> while(test <0 || test > 100){  cout<<"Test: "; cin>>test; } </em>

This prompts the user for assignment. The corresponding while loop ensures that the score s between 0 and 100 (inclusive)

<em> cout<<"Assignment: "; cin>>assgn; </em>

<em> while(assgn <0 || assgn > 100){  cout<<"Assignment: "; cin>>assgn; } </em>

This prompts the user for examination. The corresponding while loop ensures that the score s between 0 and 100 (inclusive)

<em> cout<<"Examination: "; cin>>exam; </em>

<em> while(exam <0 || exam > 100){  cout<<"Examination: "; cin>>exam; } </em>

This prompts the user for practice score. The corresponding while loop ensures that the score s between 0 and 100 (inclusive)

<em> cout<<"Practice Score: "; cin>>prctscore; </em>

<em> while(prctscore <0 || prctscore > 100){  cout<<"Practice Score: "; cin>>prctscore; } </em>

This calculates the average of the grading items

ave = (int)(classp + test + assgn + exam + prctscore)/5;

This prints the calculated average

cout <<setprecision(1)<<fixed<<"The average score is "<<ave;
