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?
Heating magnesium is a physical process.But the reaction of magnesium with oxygen at high temperature is a chemical process.
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.
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 burning magnesium oxide a chemical change or physical?
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.
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.
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.
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.
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!
Does copper sulphate undergo any physical or chemical changes during heating?
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.
Does the body produce magnesium?
No. Magnesium is an element. No chemical or biological process can synthesize elements. We get magnesium from food.
Is chemical weathering a physical process?
No, it is a chemical process.
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.
