Knowledge and skills

1. Know the reaction phenomena between common metals such as iron, aluminum, magnesium and copper and oxygen.

2. Preliminarily understand the displacement reactions between common metals and hydrochloric acid and sulfuric acid; be able to use displacement reactions to explain some chemical problems related to daily life.

Process and Method

1. Understand the basic process of scientific inquiry, be able to carry out preliminary inquiry activities, and understand the chemical properties of metals;

2. Initially learn to use methods such as comparison, induction, and generalization to process the acquired information, so that we can gradually form good study habits and methods.

Emotions, attitudes and values

1. Through the observation of colorful chemical phenomena, stimulate our curiosity and thirst for knowledge, and develop interest in learning chemistry;

2. Understand the close relationship between chemistry and daily life and production, and improve our ability to solve practical problems.

The key points of this lesson

Key points:

(1) Be able to speak proficiently about the reactions of common metals with oxygen, acids and salt solutions;

(2) The significance and use of metal activity sequence.

difficulty:

(1) Preliminarily use the chemical properties of metals to master new chemical reactions and reaction types;

(2) Use the reactions between metals and oxygen, metals and acids, metals and salt solutions to determine the activity of metals; the significance and application of the metal activity sequence table.

1. Reaction of metal with oxygen

1. What metals have we learned that can react with oxygen?

2. What are the conditions under which they react with oxygen?

Observe the combustion of aluminum foil in oxygen and write a chemical equation.

Aluminum foil can burn violently in oxygen to produce aluminum oxide. Chemical equation for the reaction:

4Al+3O2 2Al2O3

2. Reaction between metal and acid

(1) Experimental research

①Exploration tasks:

a. Explore whether iron, copper, and zinc can react with acid;

b. Compare the severity of reactions between different metals and acids.

②Experimental supplies:

Iron wire, copper wire, zinc particles, dilute hydrochloric acid (10%), dilute sulfuric acid (10%), test tube, sandpaper, tweezers

③Question thinking:

a. What steps are you going to follow to complete the above two experimental research tasks?

b. Does the experimental process require variable control? What other issues should I pay attention to?

Metal purity, dosage, acid volume and concentration, reaction temperature

Class exercises

1. After the pig iron reacts with a sufficient amount of hydrochloric acid, there will always be some residue left, and the main component of the residue is ( ).

A.Iron B.Ferric chloride

C. Ferrous chloride D. Carbon and some impurities

2. Under normal circumstances, the product of iron wire burning in oxygen is ( )

A.FeO B.Fe3O4 C.Fe2O3 D.Fe(OH)3

3. If 20 g of each of magnesium, zinc, and iron react with a sufficient amount of hydrochloric acid, how many grams of hydrogen will be produced?

(Variation: Magnesium, zinc, and iron react with sufficient amounts of hydrochloric acid to produce 2g of hydrogen. How many grams of each of the three metals magnesium, zinc, and iron participate in the reaction?)

Class summary

In this lesson, we learned two aspects of the chemical properties of metals: one is the reaction with oxygen, the other is the reaction with acid, and we also learned about the displacement reaction. In the process of experimental exploration, you must learn how to use comparative methods to analyze and summarize problems, find out patterns, deepen your understanding and mastery of knowledge, and gradually understand the differences in the chemical properties of different metals.
