Is pop fizzing a physical change?
Both. The chemical change is H2CO3 decomposing into H2O and CO2. The physical change is the dissolved CO2 forming a bubble and "fizzing" up to the surface.
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.
When A warm soda bottle fizzes when opened is it a physical change or a chemical change?
It is a physical change. The fizzing is caused by the release of carbon dioxide gas that was dissolved in the liquid, which does not involve a change in the chemical composition of the liquid itself.
Is magnesium plus oxygen a chemical or physical change?
The reaction between magnesium and oxygen to form magnesium oxide is a chemical change. This is because new substances with different properties are formed during the reaction.
When limestone fizzes when acid is added is physical or chemical change?
The fizzing of limestone when acid is added is a chemical change. This is because a chemical reaction occurs between the acid and the calcium carbonate in the limestone, resulting in the production of carbon dioxide gas.
Is fizzing is an example of physical change?
Fizzing is the result of a chemical change - a chemical reaction with gas releasing.
Is pop fizzing a physical change?
Both. The chemical change is H2CO3 decomposing into H2O and CO2. The physical change is the dissolved CO2 forming a bubble and "fizzing" up to the surface.
Is fizzing after mixing two chemicals a physical change?
No, fizzing after mixing two chemicals is a chemical change.
Is Hydrogen peroxide fizzing when applied to a wound physical or chemical change?
chemical
Is magnesium physical change or chemical change?
Magnesium is not a change of any sort. It is a metallic element that can undergo both physical an chemical changes.
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.

Shaving magnesium physical or chemical change?
It's a physical change because it might be in a different form but it's still magnesium
Is magnesium burning a physical change?
No, magnesium burning is a chemical change because the magnesium undergoes a chemical reaction with oxygen to form magnesium oxide. Physical changes do not alter the chemical composition of a substance, whereas chemical changes do.
