How many Liters are in 17.3 moles of Iron?

Answers

Answer 1

Answer:

There are 0.12269 Liters of Iron

Explanation:

First, by means of the molecular weight equation, the grams of iron corresponding to 17.3 moles can be calculated:

[tex]MW=\frac{mass(grams)}{moles}[/tex]

[tex]mass=MW*moles=55.845\frac{g}{mol} *17.3mol=966.119 g[/tex]

Then using the density equation the iron milliters are calculated:

[tex]d=\frac{mass(g)}{volume(mL)}[/tex]

[tex]volume=\frac{mass}{density}=\frac{966.119g}{7.874\frac{g}{mL} } =122.69 mL[/tex]

Milliliters to liters are converted:

122.69 mL = 0.12269 L of Iron.

Answer 2

Answer:

[tex]V_{Fe}=0.125L[/tex]

Explanation:

Hello,

In this case, given the moles of iron, we need to use it atomic mass (55.845  g/mol) and density (7.874 g/cm³) in order to firstly convert from moles to grams and secondly from grams to cubic centimetres:

[tex]V_{Fe}=17.6molFe\times \frac{55.845gFe}{1molFe}*\frac{1cm^3}{7.874gFe}=124.8cm^3[/tex]

Finally, we obtain the volume in litres by:

[tex]V_{Fe}=124.8cm^3*\frac{1L}{1000cm^3} \\\\V_{Fe}=0.125L[/tex]

Best regards.

how does the sun light affect earths climate

Answers

Answer:

The Sun powers life on Earth; it helps keep the planet warm enough for us to survive. It also influences Earth’s climate: We know subtle changes in Earth’s orbit around the Sun are responsible for the comings and goings of the past ice ages. But the warming we’ve seen over the last few decades is too rapid to be linked to changes in Earth’s orbit, and too large to be caused by solar activity

Explanation:

A typical cell phone uses wavelength of 0.36meters. How much energy does this wave have?

Answers

Answer:

55×10^-26 J

Explanation:

We can calculate the energy of the wave from

E= hc/λ

Where

h= Planks constant = 6.6×10^-34 Is

c= speed of light = 3×10^8 ms-1

λ= wavelength of the wave = 0.36 metres

Recall that cell phone use radio waves which belong to the electromagnetic spectrum hence it must possess the speed of light.

E= 6.6×10^-34 × 3×10^8/ 0.36

E= 55×10^-26 J

Hence the energy possessed by 0.36 meters wavelength radio waves is 55×10^-26 J

That means those substances have pH = 7.

When the amount of H+ is more than the amount of OH- in solution, the substance is acidic ( eg.: Lemon juice ). pH < 7

When the amount of H+ is less than the amount of OH- in solution, the substance is basic ( eg.: Baking soda ). pH > 7

What is the mole fraction of Ba(OH)2 in an aqueous solution that contains 22.8% Ba(OH)2 by mass?

Answers

Answer:

0.03

Explanation:

22.8 g Ba(OH)2 (1 mol Ba (OH)2/ 171.34 g) = 0.133 mol Ba (OH)2

77.2 g H2O (1 mol H2O/18 g) = 4.29 mol H2O

X= molar fraction= mol Ba(OH)2/ mol total

X= 0.133/ (0.133+4.29) = 0.03

0.03 is the mole fraction of [tex]Ba(OH)_2[/tex] in an aqueous solution that contains 22.8% [tex]Ba(OH)_2[/tex] by mass.

What is a mole fraction?

The ratio of the number of moles of one component of a solution or other mixture to the total number of moles representing all of the components.

Moles of [tex]Ba(OH)_2[/tex]

Moles = [tex]\frac{mass}{molar \;mass}[/tex]

Moles = [tex]\frac{22.8 g Ba(OH)_2}{171.34 g}[/tex]

= 0.133 mol [tex]Ba (OH)_2[/tex]

Moles of [tex]H_2O[/tex]

[tex]Moles = \frac{mass}{molar \;mass}[/tex]

[tex]Moles = \frac{77.2 g H_2O}{18 g}[/tex]

= 4.29 mol [tex]H_2O[/tex]

The mole fraction of [tex]Ba(OH)_2[/tex]

[tex]\frac{mol Ba(OH)_2}{total \;mol}[/tex]

Balance the following equation by adding the correct mole numbers.
P⁴+Cl²->PCl³​

Answers

Hey there!

P₄ + Cl₂ → PCl₃

First, let's balance Cl.

There are 2 on the left, and 3 on the right.

To balance this, let's put a coefficient of 3 in front of Cl₂ and a coefficient of 2 in front of PCl₃.

P₄ + 3Cl₂ → 2PCl₃

Now we have 6 on the left and 6 on the right.

Next, let's balance P.

There are 4 on the left and 2 on the right.

Let's change the coefficient in front of PCl₃ from 2 to 4.

P₄ + 3Cl₂ → 4PCl₃

There are now 4 P on each side.

However, now Cl is unbalanced, with 6 on the left and 12 on the right.

We can change the coefficient in front of Cl₂ from 3 to 6.

P₄ + 6Cl₂ → 4PCl₃

So now, we have 4 P on each side and 12 C on each side.

This is our final balanced equation.

Answers

Answer:

Limiting reactant is CS2

% yield = 131.8 %

Explanation:

Using the alanced equation given, Mole ratio of C to CS2 is 1 : 5.

That is, for every 1 mole of CS2 used, 5 moles of Carbon is produced.

35g of CS2 --- [tex]\frac{35}{76.14}[/tex] moles

= 0.4597 moles

⇒ mass of C produced = 5 × 0.4597 × 12 g/mol

= 27.6 g of C.

Percentage yield (%) = [tex]\frac{actual- yield}{theoretical- yield}[/tex]

= [tex]\frac{36.4}{27.6} * 100[/tex] =131.9%

Answers

Answer: C

# The main reason why the reaction above can not be balanced is:

   This chemical reaction SO2 + H2O -> H2SO2 is not correctly written.

    It must be: SO2 + H2O -> H2SO3

Explanation:

Note 1:

H2SO2 can be produced by the other chemical reaction:

2H2O + SCl2 -> 2HCl + H2SO2

....

Note 2: Answer A is false

As you can see in the reaction  SO2 + H2O -> H2SO3, the oxygen atoms are in two molecules on one side, but one in the other - However, this reaction is written correctly.

Note 3: Answer D is false

Of course the Sulfur atom must be placed in different places: in reactant and product molecules.

Note 4: Answer B is false

There are different kinds of chemical reactions, and this is normal that there are more molecules on one side than on the other.

The answer is C

The correct way to balance the reaction, would be to write it as SO2 + H2O →  H2SO3

Answer A is incorrect.

The oxygen atoms in the reaction SO2 + H2O -> H2SO3 are in two compounds on one end but on the other, it is in just one.

Answer D is wrong.

The sulfur atom has to be in the reactants and the products.

Answer B is not correct.

There are many types of chemical reactions . One side commonly has more atoms than the other.

Please answer this and ill mark you as brainliest

Answers

Answer:

Dark matter also called baronic matter is the matter that makes up 27% of the universe.

In 1933 it was determined as that mass that cannot be seen, that is, the non-visible mass of outer space.

Dark matter also plays a central role in the formation of structures and the evolution of galaxies and has measurable effects on the anisotropy of cosmic microwave background radiation. The composition of this matter is unknown today.

The dark matter component has considerably more mass than the "visible" component of the Universe.

Explanation:

There are certain researchers who say that the appearance of dark matter was before the appearance of the big bang.

A relevant fact of this matter is that dark matter exerts gravity, and that gravity affects the movements of objects.

Despite the fact that nothing is known about its origin, astronomers have amply demonstrated that dark matter plays a determining role in the formation of galaxies and galactic clusters, which could not maintain their cohesion without its existence, but many doubt that it is the remainder / remnant or product of a big bang.

A gas occupying a volume of 3.75L at a pressure of 0.980 arm is allowed to expand at constant temperature until its pressure reaches 0.641 atm. What is the final volume of the sample?

Answers

Answer:

Volume = 5.73L

Explanation:

Data;

V1 = 3.75L

P1 = 0.980atm

P2 = 0.641atm

V2 = ?

This question involves the use of Boyle's law, which states that, the volume of a fixed mass of gas is inversely proportional to its pressure provided that temperature remains constant.

Mathematically,

V = kP, k = PV

P1V1 = P2V2 =P3V3=........=PnVn

P1V1 = P2V2

V2 = (P1 * V1) / P2

V2 = (0.980 × 3.75) / 0.641

V2 = 5.73L

The final volume of the gas is 5.73L

Number of moles of in 4 grams of Hydrogen 4 grams is = given weight / molecular weight of Hydrogen (H₂) = 4/2 =2 Number of atoms/molecules in 2 moles of Hydrogen is (2*6.023*10²³) atoms. = 12.046*10²³ atoms.

(Hope this helps)

The number of atoms in 2 moles of helium is 1.204×10²⁴ atoms

From Avogadro's hypothesis,

1 mole of any substance = 6.02×10²³ atoms

Thus,

1 mole of helium = 6.02×10²³ atoms

With the above information in mind, we can obtain the number of atoms in 2 moles of helium as follow:

1 mole of helium = 6.02×10²³ atoms

Therefore,

2 moles of helium = 2 × 6.02×10²³ atoms

2 moles of helium = 1.204×10²⁴ atoms

Thus, we can conclude that 2 moles of helium contains 1.204×10²⁴ atoms
