Is adding magnesium and heat chemical or physical change?
Heating magnesium is a physical process.But the reaction of magnesium with oxygen at high temperature is a chemical process.
Is the reaction of magnesium sulfate and water exothermic or endothermic?
It is not a chemical reaction, it is dissolution; this physical process is exothermic.
Does the body produce magnesium?
No. Magnesium is an element. No chemical or biological process can synthesize elements. We get magnesium from food.
What is the chemical formula for magnesium dioxide?
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.
Is digestion of a candy bar a physical change or chemical change?
Chemical property
Is adding magnesium and heat chemical or physical change?

Is magnesium sulfate in water a physical or chemical change?
Dissolving is a physical process.
What is the ionic reaction of magnesium and sulfuric acid?
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.
If you melt magnesium metal is it a chemical change?
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.
Is the reaction of magnesium sulfate and water exothermic or endothermic?
It is not a chemical reaction, it is dissolution; this physical process is exothermic.
When magnesium burns in air is it chemical or physical change?
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.
Does the body produce magnesium?
No. Magnesium is an element. No chemical or biological process can synthesize elements. We get magnesium from food.
Is cutting Mg ribbon a physical change?
Yes! beacuse you are not creating a new substance and making something new just changing a the appearance!
Is chemical weathering a physical process?
No, it is a chemical process.
Is processes a physical or chemical property?
A process is not a property; and a process may be physical or chemical.
Is mechanical weathering a chemical process?
No. It is a physical process. Chemical weathering is a chemical process.
Is powdery a physical or chemical change?
Powdery is an adjective which not require any change!You can have a physical change where a large lump of some substance is ground into powder. Or you can have a chemical change (eg magnesium burning) which leaves a powdery residue.
