The dissolution of magnesium sulfate in water is a physical process. When magnesium sulfate (MgSO₄) is added to water, it separates into its constituent ions (Mg²⁺ and SO₄²⁻) but does not undergo a chemical change; the chemical identity of the compound remains unchanged. The process is reversible, as the ions can recombine to form solid magnesium sulfate upon evaporation of the water.
Heating magnesium is a physical process.But the reaction of magnesium with oxygen at high temperature is a chemical process.
Adding hydrochloric acid to magnesium ribbon results in a chemical reaction. The magnesium reacts with the hydrochloric acid to produce magnesium chloride and hydrogen gas. This process involves the breaking and forming of chemical bonds, indicating a change in the substance's chemical identity. Thus, it is a chemical change rather than a physical one.
It is not a chemical reaction, it is dissolution; this physical process is exothermic.
No. Magnesium is an element. No chemical or biological process can synthesize elements. We get magnesium from food.
The oxidation of magnesium is a process, and as such has a chemical equation rather than a formula: 2 Mg + O2 -> 2 MgO. MgO is the chemical formula for the oxide of magnesium.

When magnesium sulfate dissolves in water, it undergoes a physical change, not a chemical change. The molecules of magnesium sulfate are simply dispersed in the water, but no new chemical substances are formed.
Yes, the combustion of magnesium, or anything else for that matter, represents a chemical change. For magnesium, the combustion reaction results in the loss of magnesium and the production of magnesium oxide. Clearly a chemical change.

This process involves the breaking and forming of chemical bonds, indicating a change in the substance's chemical identity. Thus, it is a chemical change rather than a physical one.
Burning magnesium oxide is a chemical change because it involves a chemical reaction where the magnesium oxide is converted to a new substance (magnesium oxide reacts with oxygen to form magnesium oxide). This process involves the breaking and forming of chemical bonds.
The reaction of sulfuric acid and magnesium produces hydrogen gas and magnesium sulphate. The acid attacks the metal, and the balanced equation for the reaction looks like this: Mg + H2SO4 → MgSO4 + H2 gas Sulfuric acid has 2 H+ ions and one SO4 ion. The sulphate ions react with the magnesium to produce magnesium sulphate, and H2 gas is released in the process.
It is not a chemical reaction, it is dissolution; this physical process is exothermic.
Burning magnesium (or burning anything) can be described as a chemical reaction, or as a chemical change. It is not a property. However, the capacity of being able to burn, also known as flammability, is a chemical property.
Yes! beacuse you are not creating a new substance and making something new just changing a the appearance!
When heated, copper sulfate undergoes a reversible physical change where it loses its water molecules (dehydration) and changes color from blue to white. This process is purely physical and does not involve any chemical reactions.
