1. Introduction
---------------
1.1 Copyright and Disclaimer
-----------------------------
All files in the ChemLab package are copyrighted(c) by Arnold Moy
unless otherwise noted.
The software contained in this package is provided as free of charge
and therefore contains no warranty of any kind. Should the Software
prove defective, you and not the author assume the entire cost of any
service and repair. This disclaimer of warranty constitutes an
essential part of the agreement.
1.2 The ChemLab Library
-----------------------
The ChemLab library uses a graphical periodic table front-end to
display various properties for 109 elements. A total of 22
properties are listed for each element and are fully accessible to
external programs requiring access to the internal database. Other
features include a molecular weight calculator and a chemical

2. equation balancer. A light version which is about half the size of
the full version, only contains the periodic table viewer, molecular
weight calculator and chemical equation balancer.
1.2.1 Features
--------------
o graphical periodic table with element symbols
o find element by symbol
o fast property browser with 22 properties
o stack placeable properties via property browser
o internal database accessible by external programs
o compressed database
o last position preserved upon exit
o fast molecular weight calculator
o chemical equation balancer
o uses the UFL (Universal Font Library)
o works on all HP48 models (S,G,SX,GX)
o works from any port
o light version without the full database and property browser
2. Installing and Removing the ChemLab Library
----------------------------------------------
The ChemLab library requires at least 18.4K(full) or 9.5K(light)
available to install and an auxiliary library called the Universal
Font Library (UFL) must be present.
2.1 Installing
--------------
a) send either chemlb27.lib(full) or chemlt27.lib(light) to the HP48
b) put a copy of the library on the stack
c) enter the port number to store the library (0-33 GX, 0-2 SX)
d) here is an example of the stack setup so far:
--------------------------
4:
3:
2: Library 1014: CHE...
1: 0
| | | | | | |
e) at this point, press [STO]
f) perform a warmstart with [ON][C] or turn on and off the HP48
g) erase the variable containing the library. eg. 'CHEMLB27.LIB' PURGE
h) read the next section for the Universal Font Library (UFL)
requirements
2.2 Universal Font Library (UFL)
--------------------------------
The ChemLab library requires the UFL to be present. Install UFL3.LIB
which is included in this package. You must use UFL3.LIB because
FNT1 and FNT2 are required.
If you have not installed the UFL library, install it now:
a) send the library(UFL3.LIB) to the HP48
b) put a copy of the library on the stack
c) enter the port number to store the library (0-33 GX, 0-2 SX)
d) here is an example of the stack setup so far:
--------------------------

3. 4:
3:
2: Library 257: UFL...
1: 0
| | | | | | |
e) at this point, press [STO]
f) perform a warmstart with [ON][C] or turn on and off the HP48
g) erase the variable containing the library.
h) The ChemLab library is ready for use.
2.3 Bytes and Checksum
----------------------
Placing the library on the stack and executing the BYTES command:
Full version
------------
Checksum: # 4612h
Bytes: 18378.5
Light version
-------------
Checksum: # 8E79h
Bytes: 9424.5
2.4 Removing the Library
-------------------------
a) :0: 1014 DETACH
b) :0: 1014 PURGE
Depending on which port number the ChemLab library was stored, :0: in
the above example can be replaced by the appropriate port number.
3. Usage

position

MOW - molecular weight calculator
- requires a string representing a chemical formula
eg. "Ca2Fe(OH)5"
BAL - chemical equation balancer
- requires a matrix representing the chemical equation
Steps to balance:
=================
1. Label each molecule in order as A,B,C,D, etc. This will
keep track of the corresponding coefficients for later
reference.
A B C D
C2H6 + O2 => CO2 + H20
2. Create a list of individual elements in the equation as
a column down the left/right edge.
| A B C D
| C2H6 + O2 => CO2 + H20
--------------------------
C |
H |
O |
3. Inspect each individual molecule and write down how many
atoms of an element are in that particular molecule.
| A B C D
| C2H6 + O2 => CO2 + H20

5. --------------------------
C | 2 0 1 0
H | 6 0 0 2
O | 0 2 2 1
4. Create a matrix from the table in step 3.
[[ 2 0 1 0 ]
[ 6 0 0 2 ]
[ 0 2 2 1 ]]
5. Execute BAL and the answer will appear:
"2A + 7B => 4C + 6D"
A,B,C,D corresponds to the molecules labelled in step 1.
6. The final answer:
2 C2H6 + 7 O2 => 4 CO2 + 6 H20
ERSECLP - erases chemlabPAR from the hidden directory.
- see section 3.4 chemlabPAR

3.4 chemlabPAR
--------------
The ChemLab library uses a variable called chemlabPAR to store
certain parameters such as last preserved positions. chemlabPAR is
stored in the hidden directory and can be removed by using the
ERSECLP command.
