  1. Based on their Mohs hardness values, the minerals in the list are arranged in order of increasing hardness:   1. Gypsum (2.5) 2. Corundum (7-9) 3. Fluorite (4) 4. Topaz (8)   The axe would be able to scrape a line on the gypsum, as it has the lowest hardness value. The axe would also be abRead more

    Based on their Mohs hardness values, the minerals in the list are arranged in order of increasing hardness:

    3. Fluorite (4)

    4. Topaz (8)

     

    The axe would be able to scrape a line on the gypsum, as it has the lowest hardness value. The axe would also be able to scrape a line on fluorite, as it has a slightly higher hardness value than gypsum. However, the axe would not be able to scrape a line on corundum or topaz, as they have much higher hardness values than both gypsum and fluorite.
