What 2 physical properties would identify calcite?
hardness
What minerals are less dense than water?
Evenkite (CH3)2(CH2)22
What is the hardness scale of kaolinite on the mohs scale?
Kaolinite has a hardness of approximately 2-2.5 on the Mohs Scale. This means it is relatively soft and can be easily scratched by harder minerals.
How are minerals reprsented on the moh scale?
There are ten (10) minerals on the Moh's scale that represent the hardness for all minerals. Starting with the softest, #1, Talc and all minerals of the same properties all the way up till #10, Diamond being the hardest. So here's the complete table: #1 Talc #2 Gypsum #3 Calcite #4 Fluorite #5 Apatite #6 Feldspar #7 Quartz #8 Topaz #9 Corundum #10 Diamond
Identify two advantages of mining minerals?
Mining minerals has way more than two advantages, but since you asked for 2, they create jobs (for miners) and not to mention the countless uses of the atual minerals and profits.
What mineral that can scratch gypsum but cant scratch calcite?
Between 2 and 3 because its hard enough gypsum but it can not scratch calcite because calcite is harder
What are Texas's minerals?
Mineral: Location: 1) Selenite - Terlingua 2) Calcite - Terlingua
What are carbonate minerals?
Examples of carbonate minerals would be calcite, dolomite, and aragonite. These are widely distributed in the Earth's crust. Less common carbonate minerals include siderite, rhodochrosite, strontianite, smithsonite, witherite, and cerussite. Minerals that are considered to be carbonates contain the carbonate ion, CO32−
What quick test could you do to determine which is calcite and which is halite?
you can use streak by rubbing 2 minerals on a white hard surface. If the mineral leaves color its calcite and if it doesnt its halcite
What is the Mons scale?
A scale for classifying minerals based on relative hardness, determined by the ability of harder minerals to scratch softer ones. The scale includes the following minerals, in order from softest to hardest: 1. talc; 2. gypsum; 3. calcite; 4. fluorite; 5. apatite; 6. orthoclase; 7. quartz; 8. topaz; 9. corundum; 10. diamond. It should be Mohs scale. Anant
Name six types of nonsilicate minerals?
1 Copper 2 Calcite 3 Fluorite 4 Corundum 5 Gypsum 6 Galena
What if your teacher gives you two clear minerals What quick test could you do in order to determine which is halite and which is calcite?
you can rub the 2 minerals on a hard surface and if one the minerals leave a color that one is clcite and the other one that does not leave a color is halcite.
Is a No. 1 pencil harder or softer than a No. 2 pencil?
It's softer. #1 softest, #2 slightly harder, #3 harder than #2, etc.Softer.a #1 pencil is softer than a#2 pencil
What are 2 minerals that can be scratched by a fingernail?
Quartz (Mohs 7.0) and diamond (Mohs 10,0) are two of many minerals that are harder than copper (Mohs 2.5-3.0).
How can you check if a rock is calcite?
Calcite reacts to acid. The best thing to do to determine if a mineral is calcite is to place a drop of dilute hydrochloric acid on a sample. If the mineral fizzes and carbon dioxide bubbles are produced, the mineral is calcite. Place a drop of dilute hydrochloric acid on the mineral. If it fizzes and carbon dioxide bubbles are produced, the mineral is calcite.
What is the range of hardness of mohs scale?
The Moh's scale is defined as: Talc - 1 Gypsum - 2 Calcite - 3 Fluorite - 4 Apatite - 5 Orthoclase feldspar - 6 Quartz - 7 Topaz - 8 Corondum - 9 Diamond - 10 There are some minerals and substances softer then talc, however there is nothing harder then diamond.
Calcite bubbles when it comes in contact with hydrochloric acid because the calcite releases?
Either a. Quartz. b. Calcite. c. Feldspar. d. Mica
