Description

"Diamond, Graphite and C60" Carbon and Carbon Oxides PPT Courseware 2

learning target:

1. Know the similarities and differences in the composition, structure, properties, and uses of several carbon elements.

2. Know that the same element can make up different substances and understand the diversity of substances.

[Review the past and learn the new] What is a single substance?

1. Can the same element form different elements?

Yes, for example: oxygen element can make up two different elements, oxygen and ozone, and phosphorus element can make up two different elements, red phosphorus and white phosphorus.

2. Are diamond, graphite and C60 the same substance?

Diamond, graphite and C60 are not the same substance, but three different carbon elements composed of carbon elements.

Graphite - an ordinary and versatile carbon substance

graphite

Graphite is a dark gray, metallic, opaque fine flake-like solid.

Uses of graphite

Pencil lead is a mixture of graphite and clay powder.

Graphite has excellent electrical conductivity and can be used as electrodes.

Graphite is resistant to high temperatures and can be made into crucibles to smelt metals.

Self-study tips

5. Are charcoal, coke, activated carbon, and carbon black elements?

They are made up of a mixture of tiny crystals of graphite and small amounts of impurities, called amorphous carbon.

Adsorption properties of charcoal and activated carbon

Both charcoal and activated carbon are composed of tiny grains of graphite and a small amount of impurities.

What properties of activated carbon are used in the picture on the right?

C60 - the magical carbon molecule

Please state the information given in the picture and text.

⒈ C60 is a molecule.

⒉ Each C60 molecule is composed of 60 carbon atoms.

⒊ The structure of C60 molecule is shaped like a football.

4. C60 is a single substance.

power enhanced

1. Activated carbon can be used as a deodorant in refrigerators. This is how to use it ( )

A. Oxidizing B. Reducing

C. Adsorption D. Volatility

2. Activated carbon and charcoal can make red-brown NO2 gas and red ink fade because ( )

A. They are all granular and black.

B. Their main component is carbon

C. They have a loose and porous structure

D. Their density is small

3. As shown in the picture below, put a few small pieces of activated carbon in a gas collecting bottle containing reddish-brown nitrogen dioxide gas, and finally observe a reddish-brown ____ (fill in "darker" or "disappear" or "unchanged") , the liquid level in the funnel ____ (fill in "rising" or "falling" or "unchanged"). The reason is: activated carbon has a ____ effect, making the gas pressure in the bottle ____ the outside atmospheric pressure.

Summary

⒈Different elements can make up different substances; the same element can also make up different substances.

For example: diamond, graphite and C60 molecules are all elements composed of carbon elements.

2. The reason why the physical properties of diamond and graphite are different is that the order of carbon atoms is different.

3. Charcoal and activated carbon have adsorption properties. The reason is that they all have a loose and porous structure.

⒋The structure of a substance determines its properties; its properties determine its use.

What is the difference between "carbon" and "carbon"?

"Carbon": Carbon element, a chemical term. Used when writing the names of elements and the elements of carbon and carbon compounds.

"Charcoal": It is not a chemical term. Amorphous carbon is an artificial carbon substance, which contains a small amount of impurities to indicate the difference. It is often written as: charcoal, activated carbon, coke, carbon black, etc.

What happens when graphite is converted into diamond under certain conditions?

It's a chemical change because graphite and diamond are two different substances.

Is diamond steel? Is pencil lead lead?
