Description

"Carbon and Its Compounds" Fuel and Combustion PPT Courseware 2

Carbon element

1. Diamond is a simple substance of carbon and the hardest substance in nature;

2. Graphite is another carbon element, one of the softest minerals and a slippery substance;

3.C60 is also a carbon element with metallic luster, radiation resistance, high pressure resistance and chemical corrosion resistance.

Think about it:

Gas poisoning often occurs when coal is used for heating in winter. What is the reason?

Incomplete combustion:

When there is insufficient oxygen, combustibles are prone to incomplete combustion (burning is slower and less heat is released).

ignite

C+O2(insufficient)→CO

Complete combustion:

Normally, when there is sufficient oxygen, combustibles can burn completely (burn faster and release more heat).

ignite

C+O2 (sufficient)→CO2

Note: Carbon monoxide is highly toxic and can bind to human hemoglobin, thus preventing hemoglobin from combining with oxygen, causing hypoxia in the human body.

[Q] When using a coal stove to warm up a fire in winter, you need to open the window for ventilation. Why?

Because coal contains combustible carbon elements, which generate carbon monoxide and carbon black when incomplete combustion occurs.

Note: Therefore, the conditions for complete combustion of combustibles: the combustibles must be fully in contact with oxygen and have a sufficient contact area.

Carbon oxides:

Carbon monoxide and carbon dioxide are two oxides of carbon. Although there is only one oxygen atom in their molecules, their properties are very different.

Properties of carbon monoxide

Carbon monoxide is a colorless, odorless, toxic, water-insoluble gas
