Question

Heating of magnesium in water which change physical or chemical ​

Answer 1

Answer:

Magnesium gives up two electrons to oxygen atoms to form this powdery product. This is an exothermic reaction. An exothermic reaction is a term that describes a chemical reaction in which there is a net release of energy (heat).

Answer 2

The heating of magnesium in water causes a chemical change.

CHEMICAL CHANGE -

• The change that occur when one substance combines with another substance.
• It involves the rearrangement of the molecular structure.
• The change is irreversible in nature that involves either synthesis or decomposition of the substances.
• When magnesium is heated in water, it forms magnesium hydroxide and hydrogen gas.
• Magnesium reacts violently with hot water in comparison to the cold water.
• The magnesium hydroxide is a basic solution and is insoluble in water.
