i have an assignment that i have to email back my friend on identifying minerals. simple enough

the trouble is how do i write this assignment in "EMAIL FORM"

could you helped me please very please...i already finished my assignment now i just have to turn the write up in the form of an email

my assignment:

The properties used to identify minerals are:
• Crystal Form: The shape that the crystal faces (flat sides).
• Cleavage: The number of directions a mineral break.
• Hardness: Use Moh’s hardness scale numbered 1-10. Diamond is 10 (hardest) and Talc is 1 (softest). Use iron, glass, copper, and fingernail.
• Luster: How the surface of a mineral reflects light. Vitreous? Waxy? Pearly? Earthy? Metallic? Greasy?
• Streak: The color of the mineral in powdered form. Rub mineral on a piece of white porcelain and determine its color.
• Color: Most minerals have a distinctive color that can be used for identification (NOT very reliable).
• Specific Gravity: The density of the mineral compared to the density of water.
• Magnetism: Is it magnetic?
• Reaction with HCl: Does it fizzes when HCl comes in contact?

How to tell the difference between:

Calcite and Halite
The main difference between calcite and halite is that calcite reacts with acid and halite doesn’t. Another difference is their hardness. Calcite is 3 and Halite is 2.5.

Pyroxene and Amphibole
It’s difficult to tell whether it is pyroxene or amphibole because their properties are very much similar. The differences between pyroxene and amphibole are their crystal form and cleavage. Pyroxene has stubby crystals and amphibole has long crystals. Pyroxene has 2 excellent cleavages at 90 ° and amphibole has 2 excellent at 56 °.

Biotite and Muscovite
The major difference between biotite and muscovite is their color. Biotite is black or brown-black and muscovite is white or yellow. Also their streaks are different as well. Biotite has a grey or brown streak and muscovite has a white streak.

Bornite and Fluorite
There are any differences between bornite and fluorite. Bornite streak is grey-black and fluorite is white. Bornite is metallic and fluorite is vitreous. Bornite has dense brittle masses and fluorite has cubic crystals and fluorescent. Bornite has no cleavage and fluorite has 4 excellent cleavages. Bornite is denser than fluorite.

Gold and Pyrite
Gold has a yellow streak and Pyrite has a greenish black streak. Gold has flakes, grains, and is malleable while pyrite has cubic crystals. Gold hardness is 2.5-3.0 and pyrite is 6.0-6.5. Gold density is 19 and pyrite is 5.0. Gold is about 4 times denser than pyrite.

Galena and Sphalerite
Galena color is lead-grey and sphalerite is brown to yellow. Galena has a grey-black streak and sphalerite has a brown to yellow streak. Galena crystal form is cubes or massive and sphalerite has tetrahedral crystals. Galena has 3 perfect cleavages and sphalerite has 6 perfect. Galena hardness is 2.5 and sphalerite is 3.5-4.0. Galena density is 7.6 and sphalerite is 4.0.

Malachite and Olivine
Malachite has a pale green streak and olivine has a white or grey streak. Malachite luster is earthy and olivine is vitreous. Malachite reacts to acid and olivine does not. Malachite hardness is 3.5-4.0 and olivine hardness is 6.5. Malachite density is 3.6-4.0 and olivine density is 3.3.

please help and thank you...i really appreciate it

Subject: Mineral Identification Assignment

Dear [Friend's Name],

I hope this email finds you well. I have completed my assignment on identifying minerals, and I am now sharing my findings with you in the form of an email.

In this assignment, I explored the properties used to identify minerals. Here are the properties that I focused on:

1. Crystal Form: This refers to the shape of the crystal faces of a mineral. It helps in distinguishing different minerals from one another.

2. Cleavage: Cleavage refers to the number of directions a mineral can break. It is an important characteristic for mineral identification.

3. Hardness: I used Moh's hardness scale, which is numbered from 1 to 10. Diamond, with a hardness of 10, is the hardest mineral, while talc, with a hardness of 1, is the softest. To determine the hardness of a mineral, I compared it with various substances like iron, glass, copper, and a fingernail.

4. Luster: Luster describes how the surface of a mineral reflects light. It can be vitreous, waxy, pearly, earthy, metallic, or greasy.

5. Streak: Streak refers to the color of a mineral in powdered form. I rubbed each mineral on a piece of white porcelain to determine its color.

6. Color: Although not highly reliable, color can be used as an additional means of identifying minerals.

7. Specific Gravity: This property compares the density of a mineral to the density of water. It helps in distinguishing between different minerals.

8. Magnetism: I checked whether a mineral exhibited any magnetic properties.

9. Reaction with HCl: I observed whether a mineral fizzed when it came in contact with hydrochloric acid (HCl).

To further elaborate, I have also included explanations on how to differentiate between specific mineral pairs:

1. Calcite and Halite:
The main differences between calcite and halite are:
- Calcite reacts with acid, while halite does not.
- Calcite has a hardness of 3, while halite has a hardness of 2.5.

2. Pyroxene and Amphibole:
It can be challenging to differentiate between pyroxene and amphibole, as their properties are quite similar. However, the differences are:
- Pyroxene has stubby crystals, while amphibole has long crystals.
- Pyroxene exhibits 2 excellent cleavages at 90°, whereas amphibole has 2 excellent cleavages at 56°.

3. Biotite and Muscovite:
The major differences between biotite and muscovite are:
- Biotite is black or brown-black, while muscovite is white or yellow.
- Biotite has a grey or brown streak, while muscovite has a white streak.

4. Bornite and Fluorite:
Significant differences between bornite and fluorite include:
- Bornite has a grey-black streak, while fluorite has a white streak.
- Bornite is metallic, while fluorite is vitreous.
- Bornite has dense brittle masses, while fluorite has cubic crystals and is fluorescent.
- Bornite does not exhibit cleavage, while fluorite has 4 excellent cleavages.
- Bornite is denser than fluorite.

5. Gold and Pyrite:
To differentiate between gold and pyrite:
- Gold has a yellow streak, while pyrite has a greenish-black streak.
- Gold appears as flakes and grains and is malleable, whereas pyrite forms cubic crystals.
- Gold has a hardness of 2.5-3.0, whereas pyrite has a hardness of 6.0-6.5.
- Gold is about four times denser than pyrite.

6. Galena and Sphalerite:
Galena and sphalerite can be distinguished by the following characteristics:
- Galena's color is lead-grey, while sphalerite is brown to yellow.
- Galena has a grey-black streak, while sphalerite has a brown to yellow streak.
- Galena occurs in cubes or massive forms, while sphalerite has tetrahedral crystals.
- Galena exhibits 3 perfect cleavages, whereas sphalerite has 6 perfect cleavages.
- Galena has a hardness of 2.5, while sphalerite has a hardness of 3.5-4.0.
- Galena is denser than sphalerite.

7. Malachite and Olivine:
The differences between malachite and olivine include:
- Malachite has a pale green streak, while olivine has a white or grey streak.
- Malachite has an earthy luster, while olivine has a vitreous luster.
- Malachite reacts with acid, while olivine does not.
- Malachite has a hardness of 3.5-4.0, whereas olivine has a hardness of 6.5.
- Malachite has a density of 3.6-4.0, while olivine has a density of 3.3.

I hope my assignment provides you with useful information on mineral identification. If you have any further questions or need clarification, please feel free to ask.
