![Page 1: Warm-Up Write a word equation to represent the following situation: – Ammonia is an important chemical in fertilizer. It is produced by reacting hydrogen](https://reader034.vdocument.in/reader034/viewer/2022051620/56649ef55503460f94c08d50/html5/thumbnails/1.jpg)
Warm-UpWrite a word equation to represent the following situation:– Ammonia is an important chemical in
fertilizer. It is produced by reacting hydrogen gas with nitrogen gas.

Recall: Formulas for Elements• Most elements can be represented with the
element symbol: ie. Sodium Na• BUT there are 7 gas elements that always
travel in pairs: Hydrogen Iodine NitrogenChlorine Bromine OxygenFluorine
