Backpacks are often the most convenient way to carry your gear, this one is specifically designed for flying with dedicated radio pocket, headset pocket and space for fuel testers and more. For a limited time it comes with a free water bottle holder. Makes a great gift for the Student Pilot starting out this fall.

Rusting is an oxidation reaction. The iron reacts with water and oxygen to form hydrated iron(III) oxide, which we see as rust. Here is the word equation for the reaction: iron + water + oxygen â hydrated iron(III) oxide. In the experiment below, the nail does not rust when air-containing oxygen-or water is not present:usting is an oxidation reaction.
