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.

How many moles are in 187.54 grams of magnesium chlorate?

Svetlanka [38]

Hey there!

Magnesium chlorate: Mg(ClO₃)₂

Find molar mass.

Mg: 1 x 24.305 = 24.305

Cl: 2 x 35.453 = 70.906

O: 6 x 16 = 96

------------------------------------

191.211 g/mol

We have 187.54 grams.

187.54 ÷ 191.211 = 0.9808

There are 0.9808 moles in 187.54 grams of magnesium chlorate.

Hope this helps!

How do solve for density?

Pachacha [2.7K]

Density(D) is defined as Mass(M) divided by Volume(V).

The formula for Density is:

D = M / V.

Another way to remember the formula for Density is to remember "Mass per unit of volume".

I hope this helps!

an engineer wishes to design a container that will hold 12.0 mol of ethane at a pressure no greater than 5.00x10*2 kPa and a tem

OleMash [197]

Answer:

The minimum volume of the container is 0.0649 cubic meters, which is the same as 64.9 liters.

Explanation:

Assume that ethane behaves as an ideal gas under these conditions.

By the ideal gas law,

$P\cdot V = n\cdot R\cdot T$ ,

$\displaystyle V = \frac{n\cdot R\cdot T}{P}$ .

where

$P$ is the pressure of the gas,
$V$ is the volume of the gas,
$n$ is the number of moles of particles in this gas,
$R$ is the ideal gas constant, and
$T$ is the absolute temperature of the gas (in degrees Kelvins.)

The numerical value of $R$ will be $8.314$ if $P$ , $V$ , and $T$ are in SI units. Convert these values to SI units:

$P =\rm 5.00\times 10^{2}\;kPa = 5.00\times 10^{2}\times 10^{3}\; Pa = 5.00\times 10^{5}\; Pa$ ;
$V$ shall be in cubic meters, $\rm m^{3}$ ;
$T = \rm 52.0 \textdegree C = (52.0 + 273.15)\; K = 325.15\; K$ .

Apply the ideal gas law:

$\displaystyle \begin{aligned}V &= \frac{n\cdot R\cdot T}{P}\\ &= \frac{12.0\times 8.314\times 325.15}{5.00\times 10^{5}}\\ &= \rm 0.0649\; m^{3} \\ &= \rm (0.0649\times 10^{3})\; L \\ &=\rm 64.9\; L\end{aligned}$ .
