Butoxors [25]

Minerals are identified according to their properties. One of these properties is their breaking tendency: <em>cleavage</em><em> or </em><em>fracture</em>.<em> Cleavage: Calcite, mica, muscovita, pyroxene. Fracture: Quartz, Asbestos, Limestone.</em>

<u><em>Note</em></u><em>: Since I do not know which your 10 minerals are, I will provide examples of each type according to the breaking tendency.</em>

Many properties of minerals are used to identify them, such as <em>color, density, hardness,</em> among others. In this case, we are talking about their <u>breaking tendency.</u>

<h3 /><h3>How do minerals break?</h3><h3 />

Minerals can cleave or fracture.

A type of mineral breaks always in the same, and this is why the breaking tendency is useful to identify them.

<h3 />

<u>- Cleavage</u>

The mineral breaks in flat smooth planes.

Cleavage direction and smoothness of surfaces are significant when identifying.

<u>- Fracture</u>

The mineral break in irregular planes.

In these minerals, there is no particular breaking direction.

<h2 /><h3>Examples</h3>

<u>- Cleavage</u>

Calcite

Mica

Muscovite

Pyroxene

Halite

Feldspar

Gypsum

<u>- Fracture</u>

Quartz

Asbestos

Limestone

Beryl

Chromite

Agate

Copper

The concentration of a biomolecule inside a rod-shaped prokaryotic cell is 0.0037 m. calculate the number of molecules inside th

Talja [164]

First, let calculate the volume of the rod shaped-bacteria:

S = length of the bacteria * surface of its side = 4.1 * (0.45 *0.45 * 3.14) = 2.6 µm3

Now, let's convert the moles into molecules (with Avogadro's law):

0.0037mol/L = 0.0037 * 6.023 *10^23 = 2.22 *10^21 molecules / L

Now let's convert The volume and the concetrnation into µm3 (molecules / µm3)

1 L = 1 dm3 = 1000 cm3 = 1000000 mm3 = 10^9 µm3

so 2.22 *10^21 molecules / L = 2.22 10^ 12 molecules / µm3

The answer is 2.22 10^ 12 molecules / µm3

How is the structure of a nerve cell different from that of a red blood cell? Why do cells differ in shape and size? PLZ HELP!!.

ICE Princess25 [194]

Answer:

Blood cells are a lot smaller than nerve cells and have a disc-shaped structure, both great traits for moving quickly through small spaces. Their disc shape also provides them with a big surface where lots of oxygen can enter the cell.

hope it helps
