Answer:

Ductility

Explanation:

Ductility is the ability of a metal to be converted into a thin wire without getting break and loosing its hardness. The property of Ductility of a metal allows us to make a wider use of them. Some most ductile metals are gold, silver, copper etc. whereas some of the metals with very less ductility are tungsten, steel and other alloys as they are very hard to transform into a thin wire.

A metal with less ductility can be malleable as it can have the ability to be converted into a thin sheet. Not all the metals are ductile but some of them have high ductility, some have less and some of them are non ductile.

Consider the reaction Mg₂Si(s) + 4 H₂O(ℓ) → 2 Mg(OH)₂(aq) + SiH₄(g). How many grams of silane gas (SiH₄) are formed if 25.0 g of

Neko [114]

Answer:

10.60 grams of silane gas are formed.

Explanation:

From the reaction:

Mg₂Si(s) + 4H₂O(l) → 2Mg(OH)₂(aq) + SiH₄(g)

We know that the limiting reactant is Mg₂Si, so to find the mass of SiH₄ formed we need to calculate the number of moles of Mg₂Si:

$\eta_{Mg_{2}Si} = \frac{m_{Mg_{2}Si}}{M_{Mg_{2}Si}}$

Where:

m: is the mass of Mg₂Si = 25.0 g

M: is the molar mass of Mg₂Si = 76.69 g/mol

$\eta_{Mg_{2}Si} = \frac{m_{Mg_{2}Si}}{M_{Mg_{2}Si}} = \frac{25.0 g}{76.69 g/mol} = 0.33 moles$

Now, the stoichiometric relation between Mg₂Si and SiH₄ is 1:1 so:

$\eta_{Mg_{2}Si} = \eta_{SiH_{4}} = 0.33 moles$

Finally, the mass of SiH₄ is:

$m_{SiH_{4}} = \eta_{SiH_{4}}*M_{SiH_{4}} = 0.33 moles*32.12 g/mol = 10.60 g$

Therefore, 10.60 grams of silane gas are formed.

I hope it helps you!

When the temperature of a 3. 0-l sample of a gas is dropped from 200°c to 100°c, what will be the final volume of the gas sample

ipn [44]

P1V1T1=P2V2T2 Add 273 to convert degrees Celsius to Kelvin:

∴200×25/298=250×V2/273, ∴V2=200×25×273/298×250, ∴V2=18.32L

<h3>Where is the volume equation?</h3>

The basic formula for volume is length, breadth, and height, as opposed to length, width, and height for the area of a rectangular shape. The calculation is unaffected by how you refer to the various dimensions; for instance, you can use "depth" instead of "height."

<h3>What is chemistry using volume units?</h3>

Volume, which is measured in cubic units, is the 3-dimensional space occupied by matter or encircled by a surface. The cubic meter (m3), a derived unit, is the SI unit of volume.

What is the average dose of radiation that most people are exposed to every year not including dental or medical personnel deali

andriy [413]

C. The average dose of radiation that most people are exposed to every year not including dental or medical personnel dealing with X-rays is 2400 u Sv.

X-rays are a form of electromagnetic radiation, similar to visible light used for medical treatment and other forms of x ray inspection.

An X-ray, or, much less commonly, X-radiation, is a penetrating form of high-energy electromagnetic radiation.

The average dose of radiation that most people are exposed to every year not including dental or medical personnel dealing with X-rays is 2400 u Sv or 2.4 m u Sv.

Thus, the average dose of radiation that most people are exposed to every year not including dental or medical personnel dealing with X-rays is 2400 u Sv.

Would the amount of solid magnesium increase decrease or stay the same if you added a strong acid to it?

Vlada [557]

Solid Magnesium is considered as active metal so it reacts with strong acids like HCl and H₂SO₄ liberating Hydrogen gas according to the following equations:

Mg(s) + 2 HCl(aq) → MgCl₂(aq) + H₂(g)
Mg(s) + H₂SO₄(aq) → MgSO₄(aq) + H₂(g)

so the amount of solid magnesium decrease by addition of strong acid to it.
