Description

"Chemical Properties of Metals" PPT (first lesson)

Part One: Teaching Objectives

1. Know the chemical properties of metals, which can react with oxygen and acids;

2. Know the definition of displacement reaction.

Thoughts and Discussions

What are the main chemical properties of metals? In addition to common metals, what other metal elements do you know?

Chemical properties of metals PPT, part 2: reaction between metals and oxygen

1. Medicines and equipment:

a magnesium ribbon

a copper wire

a piece of wire

alcohol lamp

Think: Which metal will burn in air?

What happens to the color of the surface of the non-burning piece of metal as it cools?

The magnesium strip burns violently in the air, emits dazzling white light, generates a large amount of heat, and generates a white solid.

Iron wire can burn violently when ignited by a match and placed in an oxygen bottle.

The copper wire cannot burn in the air, it emits red light, and a black solid is formed on the surface.

Chemical properties of metals PPT, part 3: reaction between metals and acids

1. Take a small amount of magnesium strips, zinc granules, and copper sheets and put them into three test tubes containing dilute hydrochloric acid respectively, and observe the experimental phenomena:

2. Use your thumb to press the mouth of the test tube containing zinc particles and dilute hydrochloric acid, bring the burning match close to the mouth of the test tube, release your thumb and find that the phenomenon is: ____________________, the gas should be __________.

3. Take a small amount of magnesium strips, zinc granules, and copper sheets and put them into three test tubes containing dilute sulfuric acid respectively, and observe the experimental phenomenon: _______________________________________.

4. Follow step 2 to check the gas generated. The experimental phenomenon is: ____________________________

Among magnesium, zinc, and copper, the one that does not react with dilute hydrochloric acid and dilute sulfuric acid is _________.

Chemical Properties of Metals PPT, Part 4: Displacement Reaction

The reaction in which one element reacts with one compound to form another element and another compound is called a displacement reaction.

Chemical Properties of Metals PPT, Part 5: Classroom Exercises

1. Titanium (Ti), an important metal in aerospace materials, can be produced by reacting TiO2 with Si. The chemical equation of the reaction is: TiO2+Si = SiO2+Ti. This reaction belongs to the basic types of chemical reactions --- ( )

A． Combination reactionB. decomposition reaction

C. Displacement reaction D. metathesis reaction

2. The aluminum products collected by collectors in the late Qing Dynasty are still very well preserved. The main reason why the art is not easy to rust is----()

A． Aluminum is not prone to chemical reactions

B. Aluminum does not react chemically

C. Aluminum reacts poorly with acids

D. Aluminum is easily oxidized, and the oxide film on its surface protects the interior.
