Homework Answers
- Question 1:
- Answer: Muscovite mica
- Explanation: Quartz and galena have 3 directions; Feldspar and olivine have 2 directions of cleavage. Muscovite mica has one direction of cleavage.
- Question 2:
- Answer: calcite
- Explanation: Calcite is the calcium carbonate and the formula is CaCO3
- Question 3:
- Answer: Ionic
- Explanation: Ionic bonding involves transfer of electrons from one atom to another. Covalent bonding involves sharing of electrons and metallic bonding is a system of electron cloud.
- Question 4:
- Answer: specific gravity
- Explanation: specific gravity is the weight of mineral per weight of water whereas cleavage is a symmetry property, density is the mass of mineral per volume of mineral and tenacity is a strength property.
- Question 5:
- Answer: Both A & B are correct.
- Explanation: Inert elements have fully filled electrons in the outer shell which makes other element to react with them by either sharing or supplying electrons with them.
- Question 6:
- Answer: cleavage.
- Explanation: Cleavage is a physical property where the planes are considered for the mineral’s strength. Fracture is a result of failure, tenacity is a stress property, luster is a visible identification property and streak is a visible identification like color in powdered form.
- Question 7:
- Answer : calcite
- Explanation: Carbonate minerals show effervescence with acids. Calcite is also called as calcium carbonate.
- Question 8:
- Answer: streak
- Explanation: color, hardness and luster are other properties where the mineral is not powdered but viewed in direct form.
- Question 9
- Answer : luster
- Explanation: The light interacts with the crystal and the view is described by luster.
- Question 10
- Answer: Organic
- Explanation: Mineral should define crystal structure, is naturally occurring, has a definite chemical composition and is a solid.
- Question 11
- Answer : Quartz
- Explanation: Pyrite is a sulfide mineral, Halite is sodium chloride, Sulphur occurs as sulfide and sulphate minerals , Gypsum is a sulphate mineral, Quartz is silicon dioxide and falls under group of silicate minerals.
- Question 12
- Answer : Gold.
- Explanation: Gold occurs in original state with impurities.
- Question 13
- Answer: Four O and one Si atom.
- Explanation: Si atom is connected to 4 oxygen atoms by sharing electrons with silicon.
- Question 14
- Answer: minerals are confined by other surrounding minerals: 2. Poorly developed or irregular crystals. minerals are unconfined: well developed crystals
- Explanation: poorly developed crystals are characterized by clash of other minerals surrounded by them which makes it difficult to form a properly shaped crystal.
- Question 15
- Answer : ionic
- Explanation: these elements are reactive and forms ionic bonds by gathering electrons.
- Question 16
- Answer : Atomic number.
- Explanation: It is defined as the number of protons or electrons in an atom.
- Question 17
- Answer: crystal form
- Explanation: color, luster and hardness are commonly used as a diagnostic property.
- Question 18
- Answer: eight
- Explanation: the rule states that atom is stable when they have eight electrons in the outermost orbital.
- Question 19
- Answer: scratching
- Explanation: Hardness is a resistance to deformation through scratching.
- Question 20
- Answer: two directions not at 90 degrees.
- Explanation: the directions meet at 56 and 124 degrees.

In this assignment, you will identify some minerals. The
ability to identify minerals is one of the most fundamental
geological skills. It is an essential skill in identifying rocks,
for one must first identify the minerals within a rock before the
rock itself can be identified. Only after minerals and rocks have
been identified can their origin, classification, and alteration be
adequately understood. The ability for a geologist to identify
minerals by using the simplest tools is often a necessity,...

See page 302 19 Question (1 point) *Native," or elemental copper can be found in nature, but most copper is mined as oxide or sulfide minerals. Chalcopyrite (CuFeS2) is one copper mineral that can be converted to elemental copper in a series of chemical steps. Reacting chalcopyrite with oxygen at high temperature produces a mixture of copper sulfide and iron oxide. The iron oxide is separated from CuS by reaction with sand (SiO2). CuS is converted to Cu2S in the...
