Hello, it is a pleasure to serve you and give you the following answers: The reaction equation between sodium magnesium iron and water: Na+H2O NaOH + H2MG+H2O MG (OH) 2 + H2Fe + H2O Fe (OH) 2 + H2 Causes of the problem:

1.Soda-mafic-iron reaction with water may produce a lot of heat, which can cause the container**. 2.

If the reaction temperature is too high, it may lead to the formation of water vapor, which will cause the reactants to mix unevenly. Workaround and practice steps:1

Use heat-resistant containers to prevent containers**. 2.A low-temperature reaction is used to prevent the formation of water vapor.

3.Use a stirrer to ensure that the reactants are mixed evenly. Teaching:

1.In the laboratory, students should be familiar with the safe operating procedures for the reaction of soda-mafic iron with water to prevent accidents. 2.

In the lab pants virtual sail room, students should be familiar with how to use a heat-resistant container to prevent the container**. 3.In the laboratory, students should be familiar with how to use cryogenic reactions to prevent the formation of water vapor.

4.In the lab, students should be familiar with how to use a stirrer to ensure that the hail reactants mix evenly. Personal Tips:

1.In the laboratory, one should be familiar with the safe operating procedures for the reaction of soda-mafic-iron with water to prevent accidents. 2.

In the Yuno laboratory, heat-resistant containers should be used to prevent containers**. 3.In the laboratory, a low-temperature reaction should be used to prevent the formation of water vapor.

Soda-mafic reaction with water is a common chemical reaction that can generate a lot of heat and can lead to containers**. If the reaction temperature is too high, it may lead to the formation of water vapor, which will cause the reactants to mix unevenly. Therefore, in the laboratory, heat-resistant vessels should be used, low-temperature reactions should be used, and stirrers should be used to ensure that the reactants are mixed evenly to prevent accidents.

The phenomenon is the production of a large number of bubbles, after which a white precipitate is produced.

The principle of the reaction is divided into two steps:

1. The chemical properties of sodium are very active, and it reacts violently with the water in the magnesium chloride solution to generate sodium hydroxide and a large amount of hydrogen, which makes the solution produce a large number of bubbles.

The reaction equation is:

2. The generated sodium hydroxide reacts with the magnesium chloride solution to generate magnesium hydroxide and sodium chloride, and the magnesium hydroxide is a white precipitate, so there is a white precipitate in the solution.

The reaction equation is:

The phenomenon of sodium first reacting with water is very simple: high-speed rotation of bubbles heats up.

It will generate OH-, and then combine with Mg2+ to form magnesium hydroxide, which is insoluble, so the next phenomenon is: there is a precipitate formation

The chemical properties of sodium are more active than magnesium, so sodium will react with water first, and sodium will spin out a sound at high speed in edema and melt into a bright ball, and it will also produce bubbles to form NaOH

2NaOH + MgCl2 = Mg(OH)2 + 2NaCl, and Mg(OH)2 is a white precipitate.

Sodium reacts with water: 2Na + 2H2O = 2NaOH + H2

Magnesium chloride reacts with sodium hydroxide: MgCl2 + 2NaOH = Mg(OH)2 + 2NaCl

Phenomenon: Gas is formed first, followed by white precipitate.

Rotating at high speed, bubbles, heat, white precipitate.

2Na + 2H2O = 2NaOH + H2 (gas).

2NaOH + MgCl2 = 2NaCl + Mg(OH)2 (white precipitate).
