28 hardness. how easily a mineral can be scratched can be used to identify or classify which method would best help a scientist compare the hardness of three minerals? a seeing whether a fingernail can put a dent in each mineral b seeing whether each mineral can scratch the other two minerals c seeing whether each mineral breaks apart when dropped on a solid floor d seeing whether hitting each mineral with a hammer will break pieces to break off 29 use the information in table 1 to answer the question a scientist finds an unknown mineral that might be mineral y. she decides to do several tests and complete the characteristics of mineral y. identify which characteristic can be determined using each test. the types of chemicals that the strength of the make up the mineral between particles in the mineral pour some vinegar over a small piece of the mineral slowly add mass on top of a small piece of the mineral place a small piece of the mineral in a beaker of water use a rock hammer to carefully break pieces off the mineral 30 a scientist scrapes mineral w across a ceramic tile and observes a pink streak on the tile. which statement best explains how the pink streak is created? a the pink streak is created by the ceramic tile. b the pink streak is created by tiny particles of the mineral. c the pink streak is created by the pink color of the mineral. d the pink streak is created by a reaction that occurs between the mineral and the ceramic.

Answer

Brief Explanations:

When a mineral is scraped across a ceramic tile in a streak - test, the streak is made of tiny particles of the mineral that are left behind on the tile. The color of the streak can be different from the surface color of the mineral and is a characteristic property used for mineral identification.

Answer:

B. The pink streak is created by tiny particles of the mineral.
