Knowing how electrons behave in metallic materials, describe why metals make great conductors of electricity

Answers

Answer 1

Answer:

Metals are an excellent conductor of electricity and heat because the atoms in the metals form a matrix through which outer electrons can move freely. Instead of orbiting their respective atoms, they form a sea of electrons that surround the positive nuclei of the interacting metal ions.

How many moles of HCl can be produced from 0.207 g of SOC12 SOC12(1) + H2O(1) = SO2(g)+ 2HCl(g) ​

Answers

Answer:

.80*10⁻³ moles of HCl can be produced from 0.226 g of SOCl₂

Explanation:

The balanced reaction is:

SOCl₂ + H₂O ----> SO₂ + 2 HCl

By stoichiometry of the reaction they react and produce:

SOCl₂: 1 mole

H₂O: 1 mole

SO₂: 1 mole

HCl: 2 mole

Being:

S: 32 g/mole

O: 16 g/mole

Cl: 35.45 g/mole

H: 1 g/mole

the molar mass of the compounds participating in the reaction is:

SOCl₂: 32 g/mole + 16 g/mole + 2*35.45 g/mole= 118.9 g/mole

H₂O: 2*1 g/mole + 16 g/mole= 18 g/mole

SO₂: 32 g/mole + 2*16 g/mole= 64 g/mole

HCl: 1 g/mole + 35.45 g/mole= 36.45 g/mole

Then, by stoichiometry of the reaction, the following amounts of mass react and are produced:

SOCl₂: 1 mole* 118.9 g/mole= 118.9 g

H₂O: 1 mole* 18 g/mole= 18 g

SO₂: 1 mole* 64 g/mole= 64 g

HCl: 2 mole* 36.45 g/mole= 72.9 g

Then the following rule of three can be applied: if by stoichiometry of the reaction 118.9 grams of SOCl₂ produce 2 moles of HCl, 0.226 grams of SOCl₂ how many moles of HCl do they produce?

moles of HCl= 3.80*10⁻³

3.80*10⁻³ moles of HCl can be produced from 0.226 g of SOCl₂

Carbonated beverages contain dissolved carbon dioxide gas. Which temperatures are best for the liquid while it is being produced in the factory?

A. High temperatures are best to minimize the solubility.
B. High temperatures are best to maximize the solubility.
C. Low temperatures are best to minimize the solubility.
D. Low temperatures are best to maximize the solubility.

Please answer and thankyou!

Answers

Carbonated beverages contain dissolved carbon dioxide gas. Low temperatures are best to minimize the solubility. option C is correct.

Drinks that have carbon dioxide dissolved in the water are referred as carbonated beverages. The presence of this gas causes the liquid to froth.

Carbonation takes place by applying pressure. Spring water, beer and soda, and pop are a few examples of carbonated beverages. When carbon dioxide  is absorbed in a liquid, for example spring water, it absorbs Carbon dioxide from the subsurface. It can also happen naturally. Beer is  example of a naturally carbonated beverage as the brewing process produces carbon dioxide soda .

Thus option C is correct.

A sample of Element X is found to contain 82.15% of isotope type 1 (84.9118 amu)
and 17.85% of isotope type 2 (86.9092 amu). Calculate the average atomic
mass.

Answers

Answer:

Have you gotten your answer yet?

The average atomic mass of element X is 85.26 amu.

To calculate the average atomic mass of Element X, we need to take into account the abundance of each isotope and its respective atomic mass.

First, let's assign variables to the abundance and atomic mass of each isotope:

- Isotope 1: abundance = 82.15%, atomic mass = 84.9118 amu

- Isotope 2: abundance = 17.85%, atomic mass = 86.9092 amu

To calculate the average atomic mass, we can use the following formula:

average atomic mass = (abundance₁ ×atomic mass₁) + (abundance₂ ×atomic mass₂)

Substituting the values:

average atomic mass =

[tex]\dfrac{82.15\times84.9118}{100}+\dfrac{17.85\times86.9092}{100}\\=85.26 \ \rm{amu}[/tex]

Thus, average atomic mass of element X is 85.26 amu.

Then he brings home the hide, and his father cuts it into a long coil which is wound into a loop, and the boy takes his quiver and throws it on his back as if he was going on a hunt, and takes his bow and arrows in his hand. Then his father throws the loop over him, and he jumps through it. This he does five times.
