Magnesium is highly reactive to water because of the atom's electron arrangement. The products of the reaction are, heat, light, and gas, which are all indicators that they had undergone a chemical reaction.

Is putting an iron nail in sea water a physical change?
Corrosion is a chemical process.
What is the word equation for magnesium and water?
word equation : magnesium + water --> magnesium hydroxide + hydrogen chemical equation : Mg + 2H2O → Mg(OH)2 + H2
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
What is the balanced chemical reaction of Solid magnesium hydroxide decomposes into gaseous water and solid magnesium oxide?
and H(OH)
Does magnesium hydroxide dissolve in water?
Magnesium oxide does not "dissolve" in hydrochloric acid. Dissolution is a physical change. When magnesium oxide is mixed with hydrochloric acid, a chemical reaction takes place: Mg(s) + 2HCl ---> MgCl2(aq) + H2(g)
What are the Definitions of chemical and physical changes?
A physical change is a change in the physical state of a substance. An example of a physical change is water turning to ice (a solid) when frozen. Its state of matter has changed, but it is still the same substance (water).A chemical change is a change in the chemical structure of a substance(s). For example, when oxygen and magnesium react, they form magnesium oxide (a different substance). The chemical state of both the oxygen and magnesium atoms involved has changed.Equations:Oxygen + Magnesium --> Magnesium OxideO2 + 2Mg --> 2MgO
Is magnesium sulfate in water a physical or chemical change?
Dissolving is a physical process.
What is the chemical formula for magnesium and water?
Magnesium Hydroxide and Hydrogen
Is putting an iron nail in sea water a physical change?
Corrosion is a chemical process.
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 distinguishes a chemical reaction from a physical change?
Matter that undergoes a physical change has the same chemical make up as the product. For example, when ice melts, the liquid water and ice are still water with the formula H2O. In a chemical change, matter does undergo a change, so that it is no longer the same substance that you started with. For example, magnesium plus hydrochloric acid react to produce the products magnesium chloride and hydrogen gas. So the products are completely different from the reactants.
What is the chemical equation or magnesium and hydrochloric acid?
magnesium + hydrochloric acid = magnesium chloride + water
Why would water turn black when rinsing a glass coffee pot with just the coffee residue left in it?
The glass could have traces of magnesium in it which when combined with hard water would create magnesium-oxide. This chemical change would turn the water black.
What is the word equation for magnesium and water?
word equation : magnesium + water --> magnesium hydroxide + hydrogen chemical equation : Mg + 2H2O → Mg(OH)2 + H2
What is the chemical change of water?
The chemical reaction of water with sodium is a chemical change.
Why a evaporation of water is a physical changes?
It is a physical change because no chemical process is being done, only the fact that it was wet now is dry, a chemical change would be putting salt on ice.
What is the chemical formula for aqueous magnesium hydroxide?
The chemical formula of magnesium hydroxide is Mg(OH)2; this compound is extremely low soluble in water.
