Non-metallic mineral reserves consist of stone quarries and clay and sand pits; chemical and fertiliser mineral deposits; salt deposits; deposits of quartz, gypsum, natural gem stones, asphalt and bitumen, peat and other non-metallic minerals other than coal and petroleum. Metallic minerals containing valuable metals such as nickel (pentlandite), copper (chalcopyrite), zinc (sphalerite), lead (galena) and gold (occurs as a native element or as a minor constituent within other minerals) that are used in all aspects of our daily lives.
Explanation:
Mass is both a property of a physical body and a measure of its resistance to acceleration (a change in its state of motion) when a net force is applied. An object's mass also determines the strength of its gravitational attraction to other bodies.. The basic SI unit of mass is the kilogram (kg). There is no name for the color, but there is the "streak" of a mineral, meaning the color of its streak. Hardness is the ability resist scratching.
<span>Helium nuclei have a positive charge of 2+ when observed. Compared to a hydrogen nuclei, we can see that the Helium nuclei is more difficult to fuse as it has a greater charge than Hydrogen 1+. This chemical difference makes the answer true.</span>
