Question

magnesium has a melting point of 650 degrees celsius, is silvery white, and is reactive with hydrogen in water. It is capable of forming alloys with other metals and has a density of 1.74g/cm3 classify the 5 properties mentioned as either physical or chemical property. Then explain how you know the difference

Answer 1

Answer: Chemical property : It is reactive with hydrogen

Physical property : magnesium has a melting point of 650 degrees celsius, It is silvery white, it has a density of
`1.74g/cm^3` , It is capable of forming alloys with other metals

Step-by-step explanation:

Chemical property is defined as the property of a substance which is observed during a reaction where the chemical composition identity of the substance gets changed.

Example: It is reactive with hydrogen

Physical property is defined as the property which can be measured and whose value describes the state of physical system. For Example: State, density etc.

Example: 1. magnesium has a melting point of 650 degrees celsius,

2. It is silvery white.

3. It is capable of forming alloys with other metals

4. It has a density of
`1.74g/cm^3`
