Is magnesium sulphate with water physical or chemical process?
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.
Is humidifiers putting moisture into the air a physical or chemical change?
The humidifier putting moisture into the air is a physical change. It involves adding water vapor, which is a change in the physical state of water from liquid to gas, without altering the chemical composition of the water molecule.
Is putting ice in a soda to make it cold a physical or chemical change?
Putting ice in a soda to make it cold is a physical change. The ice melts into water, but it does not change the chemical composition of the soda itself.
Is putting an iron nail in sea water a physical change?
Corrosion is a chemical process.
Is evolution of gas upon boiling water with magnesium strips a chemical change?
A chemical change is a change in which molecular composition of taken reactants changes.If water decomposes to hydrogen and oxygen then it is a chemical change while freezing or boiling of water is a physical change as it's composition remains same.Now if we take the case of boiling water with magnesium strips a colorless and odorless gas is evolved which can be collected using suitable arrangements. The colorless gas can be only water vapor or hydrogen( from decomposition of water ) or it can be a mixture of both of them. If we remove the water vapor using desiccating agent from the collected gas and them test the gas for combustion we will find that it is a supporter of combustion. This shows that gas is not water vapor but hydrogen. But hydrogen was not taken initially, hence we conclude that hydrogen was produced due to decomposition of water. Since the composition has changed so it is concluded that a chemical change has occurred.Here is the chemical equation :Mg + 2H2O --> Mg(OH)2 + H2
Is magnesium sulfate in water a physical or chemical change?
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.
Mixing magnesium and the product of burning magnesium with hydrochloric acid is it a physical or chemical change?
Mixing magnesium and the product of burning magnesium with hydrochloric acid would lead to a chemical change. The reaction between magnesium oxide (product of burning magnesium) and hydrochloric acid would produce magnesium chloride and water, showing a chemical reaction taking place due to the formation of new substances with different properties.
What are the Definitions of chemical and physical changes?
A chemical change involves a rearrangement of atoms to form new substances with different chemical structures. In contrast, a physical change involves a change in the state, shape, or form of a substance without altering its chemical composition.

What is the chemical formula for distilled water magnesium sulfate and carbon dioxide?
What is the chemical formula of distilled water, magnesium sulfate and C02
What is the chemical reaction between Epsom salt and water?
When Epsom salt (magnesium sulfate) is dissolved in water, it dissociates into magnesium ions (Mg2+) and sulfate ions (SO4 2-). This dissociation process is a physical change, not a chemical reaction, as the chemical composition of Epsom salt remains the same.
