Draw Lewis structures for each of the following compounds. In
each case, specify the number of valence electrons surrounding the
central atom.
a) bromine dioxide (BrO2) (Assume the central atom
does not contain an expanded octet.)
There are ___ valence electrons surrounding the central
atom.
b) beryllium fluoride (BeF2)
There are___ valence electrons surrounding the central atom.
c) phosphorus pentabromide (PBr5)

atom.
Create an application that makes the user guess a number. The
user must be allowed tries. You must have a loop, user input
(Scanner), and a constructor. (JAVA)
Show: Create an application that allows the user to enter the
number of calories and fat grams in a food. The application should
display the percentage of the calories that come from fat. If the
calories from fat are less than 30% of the total calories of the
food, it should also display a message indicating the food is low
in fat.
One gram of fat has 9 calories, so:
Calories from fat = fat grams *9
The percentage of...
Create a C++ program that will prompt the user to input an
integer number and output the corresponding number to its numerical
words. (From 0-1000000 only)
**Please only use #include <iostream>,
switch and if-else statements only and do
not use string storing for the conversion in words. Thank
you.**
**Our class is still discussing on the basics of programming.
Please focus only on the basics. Thank you.**
Example outputs:
Enter a number: 68954
Sixty Eight Thousand Nine Hundred Fifty Four...
Java Programming
Create a program that prompts the user for an integer number and
searches for it within an array of 10 elements. What is the average
number of comparisons required to find an element in the array?
Your program should print the number of comparisons required to
find the number or determine that the number does not exist.
Try finding the first and last numbers stored in the array.
Run your program several times before computing the average.
Create design document for a program that will allow the
user:
Convert a number to binary.
Convert from binary to number.
Display the hexadecimal representation of a binary number.
Given an hexadecimal display its binary representation.
Convert a number to IEEE single precision and vice versa.
More to come.

Create an application that lets the user enter a number of
seconds and produces output according to the following
criteria:
There are 60 seconds in a minute. If the number of seconds
entered by the user is greater than or equal to 60, the program
should display the number of minutes in that many seconds.
