Asked in Fire Extinguishers
Why do fire extinguishers have carbon dioxide when fire is made out of carbon dioxide?
Fire is not made out of carbon dioxide. Carbon dioxide is a product of fire. Fire is a chemical reaction between oxygen and some flammable substance. Since most flammable materials contain carbon, most fires will produce carbon dioxide. Carbon dioxide is completely non-flammable and can cut a fire off from its supply of oxygen. ...

What is the carbon cycle and why is it called a cycle?
The carbon cycle is the cycle in which carbon moves around...well, here's a "simple" description: Humans take in oxygen and change it to carbon dioxide. Burning things and the fire itself, also releases carbon dioxide. It's not just humans; it's also animals like dogs and cats that take in oxygen and give off carbon dioxide. We do it with every breath. So, how come we don't run out of oxygen and have carbon dioxide in its place? Well, plants take in carbon...

Asked in Elements and Compounds
Does a fire give off carbon dioxide or carbon monoxide?
Either of those compounds can be produced by a fire. A well oxygenated fire will produce carbon dioxide, but if there is an inadequate oxygen supply, there will carbon monoxide. Many fires produce a mixture of both. For example, there is both carbon monoxide and carbon dioxide in the smoke that people inhale from their cigarettes (and this is one of the reasons why cigarettes are so extremely bad for your health). ...

Why is it important that plants give off carbon dioxide?
I think you have it backwards. Plants actually absorb carbon dioxide and give off oxygen. It's obvious why it's important they give off oxygen. ...
