When zinc is added to a solution of iron(II) sulfate (FeSO₄), a displacement reaction occurs. Zinc is more reactive than iron, so it displaces iron from the compound. The chemical reaction can be represented as follows: Zn(s) + FeSO₄ (aq) → ZnSO₄(aq)+Fe (s) In words, zinc reacts with iron(II) sulfatRead more

In words, zinc reacts with iron(II) sulfate to form zinc sulfate and elemental iron. The appearance of elemental iron may be observed as a change in color or the formation of a precipitate in the solution. The zinc sulfate formed remains in solution.
Ionic compounds have high melting points due to the strong electrostatic forces of attraction between positively and negatively charged ions in the crystal lattice structure.

Ionic compounds have high melting points due to the strong electrostatic forces of attraction between positively and negatively charged ions in the crystal lattice structure. Ionic compounds are composed of ions, which are formed when electrons are transferred from one atom to another. One atom loses electrons to form a positively charged ion (cation), and another atom gains those electrons to form a negatively charged ion (anion).
The positive and negative ions are held together in a three-dimensional array or lattice structure by strong electrostatic forces of attraction, often referred to as ionic bonds. These forces are quite strong and require a significant amount of energy to overcome, which is why ionic compounds generally have high melting and boiling points.
To melt or boil an ionic compound, you need to provide enough energy to break the ionic bonds and separate the ions. The higher the melting point, the more energy is required to overcome these strong forces of attraction.
In contrast, covalent compounds, where atoms share electrons rather than transfer them, generally have lower melting points because the forces holding the molecules together (intermolecular forces) are weaker than the ionic bonds in ionic compounds.
When a reactive metal reacts with dilute hydrochloric acid, the gas produced is hydrogen.

When a reactive metal reacts with dilute hydrochloric acid, the gas produced is hydrogen. The general chemical equation for this type of reaction is:
Metal + 2HCl →Metal chloride+Hydrogen gas
Now, for the specific example of iron reacting with dilute sulfuric acid (H₂SO₄), the chemical equation is as follows:
Fe(s) + H₂SO₄(aq) → FeSO₄(aq) + H₂(g)
In this reaction, iron sulfate (FeSO₄) is formed along with the evolution of hydrogen gas.
Sodium is a highly reactive metal that reacts vigorously with water and even moisture in the air. When sodium comes into contact with water, it undergoes a violent reaction, producing hydrogen gas and heat. This reaction is highly exothermic and can lead to a fire hazard.

Sodium is a highly reactive metal that reacts vigorously with water and even moisture in the air. When sodium comes into contact with water, it undergoes a violent reaction, producing hydrogen gas and heat. This reaction is highly exothermic and can lead to a fire hazard.
To prevent sodium from reacting with moisture in the air, it is often stored immersed in a non-reactive substance, such as kerosene oil. Kerosene forms a protective layer around the sodium, preventing it from coming into contact with water vapor or atmospheric moisture. This helps to minimize the risk of uncontrolled reactions and fires.
The use of kerosene oil or other inert substances for storing reactive metals is a common practice in laboratories and industrial settings where such metals are used. It ensures the safe handling and storage of these materials.
