Question

Дополниье реакции. 1) SO3 + H2O …. 2)Zn + CuSO4

Answer 1

1) H2SO4

2) ZnSO4 + Cu

Answer 2

1) The reaction between sulfur trioxide (SO3) and water (H2O) is an example of an acid-base reaction. When SO3 reacts with water, it forms sulfuric acid (H2SO4). The balanced chemical equation for this reaction is:

SO3 + H2O → H2SO4

In this reaction, SO3 acts as an acid because it donates a proton (H+) to water, which acts as a base. The resulting product, sulfuric acid (H2SO4), is a strong acid commonly used in various industrial processes.

2) The reaction between zinc (Zn) and copper sulfate (CuSO4) is an example of a single displacement reaction. When zinc reacts with copper sulfate, it displaces copper from the compound and forms zinc sulfate (ZnSO4). The balanced chemical equation for this reaction is:

Zn + CuSO4 → ZnSO4 + Cu

In this reaction, zinc acts as a reducing agent because it donates electrons to copper ions, reducing them to copper metal. Copper sulfate, on the other hand, acts as an oxidizing agent because it accepts electrons from zinc, oxidizing it to zinc ions. This reaction is commonly used in electrochemical cells, such as batteries, where the flow of electrons generates electrical energy.
