"Diamond, Graphite and C60" Carbon and Carbon Oxides PPT Courseware 3

What element is this?

Do you know what elements oxygen can form?

Please guess whether carbon element can form different elements?

Can you tell me what you have learned about carbon?

Do you know what substances contain carbon?

The chemical properties of carbon elements are basically similar

The physical properties of carbon elements vary greatly, but what about their chemical properties?

Experimental exploration

Use tweezers to hold a piece of charcoal, heat it red with an alcohol lamp, put it into the oxygen bottle, then add a small amount of clarified lime water, oscillate and observe the changes.

Summary of reflection:

What did you gain from this class? What did you learn?

practice

1. "Scientific prevention and defeat of influenza A" is an important measure for the people of the country to fight against influenza A in 2009. Wearing a mask containing activated carbon can prevent influenza A because of the _____ of activated carbon.

2. Connect the following substances on the left with the uses on the right.

Graphite refrigerator deodorant

Diamond as electrode

Coke to make ink

Activated carbon for drill bits

3. Below is a schematic diagram of the structure of several elements of carbon. The small circles in the picture represent carbon atoms.

(1) According to the fact that the layers of nail material can slide between each other and have a slippery feel, one of its uses is ________.

(2) The chemical formula of substance B in the picture is C60. It is known that a simple substance of silicon also has the same number of atoms and a similar structure as substance B. Some scientists have tried to put a molecule of substance B into a single substance of silicon. In the molecule, the reaction forms a new type of molecule with the chemical formula _________.

4. After scientists discovered the C60 molecule in 1985, scientists discovered a tubular carbon substance—carbon nanotubes—in 1991. Please use the knowledge you have learned to answer the following questions.

(1) Are the chemical properties of C60 molecules and carbon nanotubes active at room temperature? Briefly explain the reasons.

(2) Design a plan to prove that C60 molecules and carbon nanotubes are composed of carbon elements.
