calculate the number of moles of Cu in 2.4x10^21 atoms of Cu
Answer:
0.004 molesExplanation:
To find the number of moles in a substance given it's number of entities we use the formula
[tex]n = \frac{N}{L} \\[/tex]
where n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question we have
[tex]n = \frac{2.4 \times {10}^{21} }{6.02 \times {10}^{23} } \\ = 0.003986[/tex]
We have the final answer as
0.004 molesHope this helps you

The Great Fire of 1910 burned through parts of North Idaho,
western Montana, eastern Washington, and southeastern
British Columbia. Many small fires and several large fires that
were started by an electric storm coalesced into one "Big
Blowup" of unprecedented size that lasted two days.
Hurricane-force winds spread the firestorm; trees became
blowtorches, sucking fire from the ground and hurling it in
several directions, spreading the fire on contact. Witnesses
described fireballs being flung like cannons. Trees exploded
like fireworks. The fire killed 87 people, destroyed several
towns in its path, and burned more than three million acres of
forest

The Great Fire of 1910 that burned through parts of North Idaho, western Montana, eastern Washington, and southeastern British Columbia serves as a model of conduction as the fire spread from tree to tree without actual movement of the trees away from their position but as a result of contact between the burning flames in the trees.
What are the processes of heat transfer?Heat transfer processes refers to the process by which heat energy is transferred from one point to another within a medium of between two points.
There are three processes of heat transfer, namely:
ConductionConvection, and RadiationConduction is a process of heat transfer in which is transferred from one point to another in a medium without the actual movement of the particles of that medium.
During conduction, the particles of the medium vibrate about a mean position as they acquire heat. This heat energy is then transferred from that particle to the neighboring particle as they particles are in close contact. Hence the heat is transferred from one particle to the next.

Which state of matter has a definite volume but can change its shape?
A.) Solid
B.)gas
C.)liquid
Answer:
solid
Explanation:
because solid has a definite shape and volume
Answer:
Liquid
Explanation:
This is because the intermolecular forces of attraction are strong enough to hold the molecules together but not so strong as to fix them into definite positions (as in solids). Instead, they possess fluidity and hence no definite shape.

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!
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.
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.

Why do you sound weird when you hold your your nose and talk?
Answer:
People with a nasal voice can sound as though they're speaking through a clogged-up or runny nose, which are both possible causes. Your speaking voice is created when air leaves your lungs and flows upward through your vocal cords and throat into your mouth. The resulting sound quality is called resonance. (i hope i helped ya )

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