Relational operators are used to compare the values of two variables or expressions and determine if
they are equal to each other, unequal to each other, or whether one is less than or greater than the
other. Java has 6 relational operators, and all a
Java defines eight (8) fundamental data types. These fundamental types are referred to as primitive
types, and you can define variables that store data that fall into one of three categories:[*] Integer or
floating point values. There are 6 primitive
[*] Java variables are used in Java programs to store information while the program is running. The
values for variables may be assigned and changed while a program is running, and Java stores the values
for variables in main memory. A Java programmer

Explain why water is a polar molecule.
o Water is a triatomic molecule. The oxygen atom forms a covalent bond with each of the
hydrogen atoms. Oxygen has a greater electronegativity and therefore attracts the
electron pair of t

If a combustion problem states that excess oxygen is available, we need not concern ourselves with
the oxygen-to-water ratio. The mass of water produced is predicted from (and limited by) the mass of
hydrogen available. Of
