D. by specific gravity​

Answer 1

Answer:

Explanation:

By Crystal Shape

Answer 2

To distinguish amphibole from olivine based on a)crystal structure

Explanation:

by Crystal shape

• Amphibole is a dark-colored mineral with a Mohs hardness of 5 to 6. The most common amphibole is hornblende.
• It has a transparent appearance and a glassy gloss. It has very long and thin crystals. Olivine is a silicate mineral with a general chemical composition of (Mg, Fe)2 SO4, however, magnesium and iron can be replaced with calcium, manganese, and nickel.
• It is noted for its distinctive olive-green hue and is frequently referred to as peridot in the gemstone business.
• It is a translucent, glassy substance that is nearly as hard as quartz. Its crystals are granular in appearance.

by luster

• In mineralogy, luster refers to the look of a mineral's surface in terms of light-reflective properties.
• The refractive power, diaphaneity (degree of transparency), and structure of a mineral determine its luster.
• The term "luster" relates to how a mineral surface appears in reflected light.

by basicity

• The difficulty for acid to react with a base is dictated by the number of hydrogen atoms that can be replaced in the acid.
• Basicity is defined as the condition of being a base.
• Sodium hydrochloride is an example of a basic substance.

by specific gravity​

• Specific gravity, often known as relative density, is the ratio of a material's density to that of a reference substance.
• Specific gravity has no dimension because it is the ratio of two quantities with the same dimensions (mass per unit volume).
