Type of silicate minerals is shown from this arrangement of silicon tetrahedron: B. single chain

<h3>Further explanation </h3>

Silicate minerals are rock-forming minerals made up of silicate groups. Silicate minerals are the largest class of minerals because it make up approximately 90 percent of the Earth's crust. Silica SiO₂ is usually considered a silicate mineral. Silica tetrahedra, made up of silicon and oxygen, form chains, sheets, and frameworks, and bond with other cations to form silicate minerals.

Single chain silicates contain silica tetrahedra that are linked up in a chain by sharing two oxygen atoms. The most common single chain silicate is pyroxene. In single-chain silicates, tetrahedra link to form a chain by sharing two oxygen atoms each. A common mineral in this group is pyroxene.

Pyroxene is any of a large class of rock-forming silicate minerals, generally containing calcium, magnesium, and iron and typically occurring as prismatic crystals

In pyroxene, silica tetrahedra form a chain because one oxygen from each tetrahedron is shared with the adjacent tetrahedron.

Since no choices are given, I would just give the 6 possible tetrahedron structures of silicate minerals. Then, it will be up to you to distinguish which one fits to your choices.

1. Isolated tetrahedra - they are separated by positive charges. An example would be olivine.
2. Ringed tetrahedra - they are linked together by positive charges, like that of tourmaline.
3. Tetrahedra - oxygen is shared by two neighbors like that of the pyroxene family.
4. Double chains/Ribbons - example whould be the amphibole family
5. Silica Sheets - when oxygen is shared by three adjacent molecules like the micas and the clay minerals.
6. Three-dimensional framework - four oxygen atoms are linked to other tetrahedra like feldspar and quartz.

What is an example of equilibrium?

frez [133]

A good example of equilibrium would be the mixing of oil and water in a closed container.

<h3>What is chemical equilibrium?</h3>

Chemical equilibrium is a condition in which the concentrations of components of a chemical reaction remain unchanged and have no tendency to change.

Of all the options, the only one where the concentrations of the component reactants cannot change is a mixture containing oil and water in a closed container.

Oil and water are immiscible and thus, their concentrations remain constant.

99 POINTS!!!!!! PLEASE HELP ASAP!!!!!

ohaa [14]

What you can do is organize them by color, what matter they are in room temperature, their molecular structure, or what kind of conductor in electricity and heat it is. I'm not sure what the format is supposed to look like but first just organize them all in different categories.

Potassium cyanide is a toxic substance, and the median lethal dose depends on the mass of the person or animal that ingests it.

kakasveta [241]

Answer:

The volume will be 89.6875 ml

Explanation:

So to count this we will use a single proportion.

0.0640 mol - 1000 ml

5.74×10−3 mol - x ml

x ml=5.74×10−3 mol*1000 ml/0.0640 mol=89.6875 ml

What tests can you do to identify gases, based on their chemical properties?

GuDViN [60]

Tests for gases
Hydrogen, oxygen, carbon dioxide, ammonia and chlorine can be identified using different tests.
Hydrogen. A lighted wooden splint makes a popping sound in a test tube of hydrogen.
Oxygen. A glowing wooden splint relights in a test tube of oxygen.
