The following properties are of metal lithium. classify them as chemical or physical.

1.) reacts violently with chlorine to form a white solid.
2.) burns in oxygen with a bright red flame
3.) changes from silvery gray to black when placed in moist aitlr
4.) silvery gray in color
5.) in the liquid state reacts spontaneously with its glass container, producing a hole in the container
6.) light enough to float on water
7.) can be cut with a sharp knife
8.) boils at 1317°c in the liquid state

Explanation:

We have to classify the properties as chemical or physical for metal lithium  in given   properties

Physical property:It is define as that  property in which no chemical reaction occurs.

Chemical property:It is that property of substance in which chemical reaction takes place.

Physical property

- "the choice that is not an indicator of a chemical change is "state of matter changes". more common than not, chemical reactions produce energy in the form of light or heat. along with energy, they also produce a new substance called the product that could be in any state of matter (solid, gas, or liquid)."
