2 | You can use an address on the 'r' command to read input at a particular | |
3 | location in the file. Thus | |
4 | 5r name | |
5 | reads file "name" and appends its contents after line 5 o f the file. | |
6 | You can use any kind of address, including a search. Here is a file "chem". | |
7 | Find the line in file "chem" which contains the word "eight"; | |
8 | read the file "more" and append it after that line. Then rewrite | |
9 | "chem" and type "ready". | |

11 | When elements combine to form compounds, the electrons in the | |
12 | outermost shell of the atoms are the only ones that take part in the | |
13 | reaction. These electrons are either transferred from the outer | |
14 | shell of one atom to the outer shell of another, or, in some cases, | |
15 | shared with the electrons in the outer shell of the second atom. | |
16 | Whether the electrons are transfered to the second atom or shared, | |
17 | this atom completes its quota of eight electrons in the outer shell. | |
18 | An oxide is a compound containing oxygen and one other element. | |
19 | The simplest of the oxides is H2O -- pure water, or hydrogen oxide. | |
20 | Carbon dioxide is CO2 and is formed during the burning of organic | |
21 | matter such as wood, paper, gasoline, or coal. In the same burning | |
22 | process, H2O is formed and energy is released, generally as heat, | |
23 | sometimes as light. Carbon dioxide is in the breath you just | |
24 | exhaled. This gas is given off by decaying plant and animal matter. | |
25 | Decay is a burning process. | |
26 | Oxidation is a word that covers all the different ways things | |
27 | burn. When something oxidizes, it is burning. | |
28 | Compounds which are formed by the interchange of electrons are | |
29 | called ionic compounds. The ions formed are said to possess | |
30 | electrovalence. | |
