So, given today's subject is all about chemical reactions, we couldn't be in better company. We're looking at combustion and oxidation in relation to chemical reactions. I mean, it sounds really ...

All combustion reactions (such as the burning of coal) are exothermic. Incredibly, the reaction between iron and moist air that produces rust is a very exothermic process and generates lots of heat.

This module connects ideas across topics in a first semester introductory chemistry course to explore the impacts of combustion reactions. By motivating students to understand the relationship between ...

This demo is done most commonly with the copper hydrogen cone apparatus. After filling the apparatus with hydrogen, the hydrogen gas escaping through the hole in the cap is ignited and burns quietly ...

A balloon filled with helium and one filled with hydrogen are ignited. Hydrogen provides a loud explosion and flame. He(g) + O 2 (g) → N.R. Light the candle on the end of the yardstick and lower the ...

where Q is the heat of combustion. In this reaction, atoms are conserved and the equation balances for each of the species. The reaction is a stoichiometric reaction, and the coefficients multiplying ...

air and recirculated burnt gas are intensively mixed before combustion reactions start. This prevents local temperature peaks and strong nitrogen oxide formation in the flame. When the concept was ...
