Description

"Carbon and Its Compounds" Fuel and Combustion PPT Courseware

1. Carbon element

1. Diamond

Properties: Transparent, translucent or opaque solid, the hardest substance in nature, wear-resistant and corrosion-resistant.

Usage: cutting glass, drilling ore, cutting metal bearings, etc.

2. Graphite

Properties: Dark gray metallic luster, opaque fine phosphorus flake solid, soft and greasy, can withstand high temperatures, and is a good conductor of heat and electricity.

Usage: Making pencil leads, electrodes, etc.

3. Activated carbon

Properties: loose and porous, with good adsorption properties.

Usage: used for decolorizing oils, beverages, food and drinking water, etc.

4. Sodium

Properties: metallic luster, radiation resistance, high temperature resistance, high pressure resistance, superconducting, chemical corrosion resistance

Why do the same elements of carbon have different properties?

Carbon atoms are arranged in different ways

[Summarize]:

1. The same element may form many different elements. Therefore, pure substances composed of the same elements are simple substances.

2. Multiple elements may be composed of one element.

2. Carbon oxides

(1) Carbon monoxide (CO)

1. Nature (P95)

Carbon monoxide reacts with oxygen

carbon monoxide + oxygen → carbon dioxide

CO O2 CO2

(2) Carbon dioxide (CO2)

experiment

Properties of dioxide:

Chemical properties:

1. Carbon dioxide does not burn and does not support combustion under normal circumstances.

2. Carbon dioxide can make purple litmus test solution turn red.

carbon dioxide + water → carbonic acid

CO2 H2O H2CO3

3. Carbon dioxide can make clear lime water turbid.

Carbon dioxide + calcium hydroxide → calcium carbonate + water

CO2 Ca(OH)2 CaCO3 + H2O

Laboratory preparation of carbon dioxide

1. Drugs: dilute hydrochloric acid limestone (or marble)

2. Principle: dilute hydrochloric acid + calcium carbonate → calcium chloride + water + carbon dioxide

HCl CaCO3 CaCl2 H2O CO2

3. Device: See the book (P 98)

4. Collection method: upward air exhaust method (Question 1: Why can the upward air exhaust method be used? 2. Why can’t the drainage method be used for collection)

5. Full inspection and verification

Check for fullness: Use the burning bar to reach the mouth of the bottle. If the bar goes out, it proves that the collection is full.

Verification: Pour in clear lime water. If the clear lime water turns cloudy, it proves that it is carbon dioxide.

3. Calcium carbonate (CaCO3)

chemical properties

high temperature

Calcium carbonate → calcium oxide + carbon dioxide

CaCO3 CaO CO2

(quicklime)

Calcium oxide + water → calcium hydroxide

CaO H2O Ca(OH)2
