Correct, a 5 hardness can scratch a 5 and below.
Successful fossilization or preservation of an organism can occur in several ways: (1) preservation without change; (2) complete replacement by a mineral; (3) filling in of a hollow space by a mineral; (4) formation of a thin film of carbon; and (5) formation of an imprint or the filling in of an imprint.
Hardness test: Determining the mineral's hardness using Mohs scale. Streak test: Observing the color of the mineral's powdered form. Acid test: Reacting the mineral with acid to observe effervescence. Magnetism test: Checking if the mineral is attracted to a magnet. Cleavage or fracture test: Assessing how the mineral breaks when subjected to stress.
The mineral with a Mohs hardness value of 7 (such as quartz) would scratch the mineral with a value of 5 (such as apatite). This is because a mineral can scratch any other mineral with a lower Mohs hardness value.
The 7 would wear away the 5.

Einsteinium is used only for nuclear physics research or as a raw material to obtain new heavier isotopes.
Five different ways in which minerals are used are1.electronics,2.jewelry,3.coins,4.in construction,5.in foods
5+10+10 5+5+5+10 5+5+5+5+5 5+20 Four ways.
There are 5 choices for the first digit, as any of the 5 given digits can be used. After selecting the first digit, there are 4 remaining choices for the second digit, and 3 choices for the third digit. Therefore, the total number of ways to write a 3-digit positive integer using the given digits without repetition is 5 x 4 x 3 = 60 ways.
