Question

Question 2 (1 point)
A student wants to conduct an investigation to describe a chemical property that could be used to distinguish between two compounds. Which investigation would work best?

a
An investigation comparing the melting points of two compounds.
b
An investigation comparing which of the two compounds is combustible.
c
An investigation comparing the color of two compounds at room temperature.
d
An investigation comparing how the two compounds dissolve in water.

Answer 1

Answer: b

Justification: Combustibility (flammability) is a chemical property because it involves a substance undergoing a chemical change (reaction with O2). Melting point and color are physical properties, and solubility/dissolving is generally a physical property.
