Instructions:
Subscripts are indicated using an underscore, i.e molecular oxygen
is indicated as O_2, while water is H_2 O (the space after the
2 is optional).<p>
If the subscript requires more than one character, it is placed in
curly brackets, i.e., H_{2x}O would put the 2 and the x below the line.
<p> 
Superscripts are indicated using the caret (^), and curly brackets
are used to group superscripts also.
The exponential, e^{2x^2} is &quot e to the power (2 times x squared)
&quot . Note, the x is squared, not the 2, (2*x*x) and all of this is in 
the exponent.<P> ===============SOME SELECTED UNITS====================<br>R = 8.314 J/(mole &#176K) = 1.987 cal/(mole &#176K) = 0.082 liter-atm/(mole &#176K)<br>0&#176C = 273.16&#176K<br>1.01325bar = 1atm<br>N_{Avogadro} = 6.02486E^{23} molecules/mole<br>h = 6.627E^{-27} erg-sec<br>c = 2.99793E^{10} cm/sec<HR><br>charge on the electron = 4.80286E^{-10} esu<br>mass of electron = 9.1055E^{-28} gram<br>mass of proton = 1.67312E^{-24} gram
