Question

Как понять с чем реагируют металлы

Answer 1

Как правило, классы неорганических соединений реагируют с противоположными по свойствам классами. Так металлы будут иметь основные свойства и реагировать с классами, имеющими кислотные свойства. Тут всё просто) Металлы будут реагировать
1) с неметаллами (по принципу противоположное с противоположным)
2) с кислотами, НО металлы только до Н2 в эл-химическом ряду напряжений (кроме щелочных и щёлочно-земельных)
3) с солями , если металл более активный чем металл в соли. Он будет вытеснять металл из соли 
4) Ну и наконец с водой Н2О. но только стоящие до водорода опять же. Щелочные и щёл-земельные легко, а вот остальные только под температурой:) 
Удачи в изучении химии!

Answer 2

Металлы реагируют с неметаллами, с кислотным оксидом, с кислотой и с солями.

Answer 3

Understanding How Metals React

Metals can react with other substances, such as acids or other metals, to form new compounds or undergo chemical changes. The reactivity of metals depends on various factors, including their position in the periodic table and their electron configuration. Let's explore how metals react with different substances.

Reactivity of Metals with Acids

Metals can react with acids to produce a salt and hydrogen gas. The general equation for this reaction is:

Metal + Acid → Salt + Hydrogen gas

For example, when magnesium (Mg) reacts with hydrochloric acid (HCl), it forms magnesium chloride (MgCl2) and hydrogen gas (H2):

Mg + 2HCl → MgCl2 + H2 Different metals have different reactivities with acids. Some metals, such as magnesium and zinc, react readily with acids, while others, like gold and platinum, do not react with most acids.

Reactivity of Metals with Other Metals

Metals can also react with other metals to form alloys or undergo displacement reactions. In a displacement reaction, a more reactive metal displaces a less reactive metal from its compound.

For example, when zinc (Zn) is added to a solution of copper sulfate (CuSO4), a displacement reaction occurs, and zinc displaces copper from the compound:

Zn + CuSO4 → ZnSO4 + Cu The reactivity series of metals provides a useful guide to predict displacement reactions. Metals higher in the reactivity series can displace metals lower in the series from their compounds.

Factors Affecting Reactivity

The reactivity of metals is influenced by several factors, including:

1. Position in the Periodic Table: Metals on the left side of the periodic table, such as alkali metals and alkaline earth metals, are generally more reactive than transition metals on the right side. 2. Electron Configuration: Metals with fewer valence electrons are generally more reactive because they are more likely to lose electrons and form positive ions. 3. Nature of the Reacting Substance: The concentration and nature of the substance the metal is reacting with can also affect its reactivity. For example, the concentration of an acid can influence the rate of reaction with a metal.

Conclusion

In summary, metals can react with acids and other metals to form new compounds or undergo displacement reactions. The reactivity of metals depends on their position in the periodic table, electron configuration, and the nature of the reacting substance. Understanding how metals react is important in various fields, including chemistry, materials science, and engineering.
