e. has a melting point of$-{220}^{o}C$

Short answer

a. chemical

b. physical

c. physical

d. chemical

e. physical

Step-by-step solution

introduction

Physical property can be noticed or estimated without changing the component, similar to variety, shape and volume whereas chemical properties depict the capacity of a substance to change into another substance.

explanation

a.The reactivity of a component is a substance property. It demonstrates how fluorine responds with different components to make a compound. Fluorine is the most responsive nonmetal in the gathering.

b.Gas addresses the actual condition of a component. It addresses how it exists at room temperature. Thus, this is actual property.

c.Variety is an actual property that can be noticed straightforwardly without changing the personality of the component.

d.Fluorine when interacts with hydrogen responds with it and the response is profoundly exothermic. A huge measure of intensity is delivered in the type of blast. The substance character of the component gets changed. Along these lines, it is a synthetic property.

e.Melting point mirrors an adjustment of state from gas to fluid here. The synthetic personality doesn't change, just the state is changed. Thus, it is actual property.
