Which of the following properties is a chemical property of phosphorus?
a) it burns in air
b) it is a white waxy solid
c) it melts to form a viscous liquid at 44.1 oC
d) Both a and c are both examples of chemical properties.
e) a, b, and c are examples of chemical properties.
i think it's A? but confused about B and pretty sure it's not C
You are correct that it is A. Color, melting point, boiling point, size, density, etc are physical changes. b is a physical change as is c.
