Answer to Question 1

According to Figure 2.4, fluorite is 20 times harder than talc and gypsum is 2 times harder than talc, so fluorite is 10 times harder than gypsum.

Answer to Question 2

Color is not a useful property in identifying a mineral because a mineral's color can vary significantly with very small changes in composition and because many different minerals can be the same color.
