Answer:

C1V1=C2V2

C1 is 2.0mol/l

V1=?

C2=.4mol/L

V2=100ml or for this 0.1L

V1 is 20ml

Best way to prepare this is to measure out 20ml of the 2 molar solution and add 80mL to it to get to 100mL

Answer:

50 moles of many mango seeds = 2.107.10²⁴ mango

Further explanation

A mole is a unit of many particles (atoms, molecules, ions) where 1 mole is the number of particles contained in a substance that is the same amount as many atoms in 12 gr C-12

While the number of moles can also be obtained by dividing the mass (in grams) with the molar mass of element or molecule

With  Avogadro's number

N = number of gas particles

No = Avogadro number (6.02.10²³)

n = number of moles

n= N/No

3.50 moles of many mango seeds are comparable to

N mango seeds= 3.5 x 6.02.10²³

N mango seeds=2.107 x 10²⁴..

Answer:

6.27 X 10^26 atoms

Explanation:

Write down the formula:

number of moles = mass/Ar    (Ar is atomic mass)

Ar of carbon = 12

mass = 12.5kg or 12500g

Substitue these values into the formula:

number of moles = 12,500g / 12 = 3125/3 or 1041.6

Convert this to atoms:

1 mole = 6.022 X 10^23 atoms

So, 1041.6 moles = 6.27 X 10^26 atoms

When a plate moves it shifts the earth, and it can cause an earthquake.

A fault is where two of earth's tectonic plates come together. They can slide against the other, causing earthquakes, they can push against each other causing mountains to form, and they can move apart from each other, causing  valleys or trenches.

The atoms of helium are required to equalize the mass of a silver atom is 8.4 x 10 ⁻⁴⁸.

Atoms are the minute particles that are present inside elements.

Atomic mass of silver is 107.86 g/mol

Mass of one atom of silver will be

[tex]\dfrac{ 107.86 }{6.022 \times 10^{-23}} = 1.79 \times 10^2^4[/tex]

Atomic mass of helium is 6.941

[tex]\dfrac{6.022 \times 10^{-23}}{4.0 \times 1.79 \times 10^2^4 } = 8.4 \times 10^{-48}[/tex]

Thus, the atoms of helium are required to equalize the mass of a silver atom is 8.4 x 10 ⁻⁴⁸.

Physical

Explanation:

Physical weathering is defined as the geological process in which rocks are broken down but there is no change in their chemical composition.

Granite tor are the rock masses above the ground surface which are  associated with granites

Granite Tor is an example of physical weathering as they formed by freeze–thaw weathering. Granite tor are formed when magma present in the crust cools down and form batholith. Rocks above batholith gets erodes and left the batholith to expose.

Hence, the correct answer is "Physical weathering'.

Answer:

it readily gains another electron. the outer electron shell is closer to the nucleus, than iodine for example, which makes it less shielded (greater attraction for another electron = violent reaction to get it)

I believe it is Avogadro's number: 6.022 × 10²³

Explanation:

One mole of a substance is equal to 6.022 × 10²³ units of that substance

The given reaction is an example of displacement reaction. Here, one mole of oxygen reacts with one mole of oxygen molecules. Hence theoretically 32 g of sulphur needs 32 g of oxygen.

Displacement reactions are a kind of reactions where one element or group is displaced with other element or group. There are both single displacement and double displacement reaction.

The reaction of sulfur oxide with metallic copper producing copper oxide and copper sulphide is an example of single displacement reaction. The prior reaction for this is the combination of sulfur and oxygen.

Here, one mole of oxygen reacts with one mole of oxygen molecules. Hence theoretically 32 g of sulphur needs 32 g of oxygen. Thus each is reacting in 1 :1 ratio and giving the oxide of sulfur.

Answer:

Explanation:

A supersaturated solution is unstable—it contains more solute (in this case, sugar) than can stay in solution—so as the temperature decreases, the sugar comes out of the solution, forming crystals. The lower the temperature, the more molecules join the sugar crystals, and that is how rock candy is created.

Answer:

B. (NH₄)₃PO₄

Explanation:

Elevation of boiling point is one of the colligative properties.

Formula is: ΔT = Kb . m . i

ΔT = Boiling T° of solution - Boiling T° of pure solvent.

i = Van't Hoff factor (numbers of ions dissolved)

Kb = Ebulloscopic constant

In this case, all the m are the same so let's dissociate the salts:

NaI → Na⁺  +  I⁻     i = 2

(NH₄)₃PO₄ → 3NH₄⁺  +  PO₄⁻³     i = 4

NaBrO₄  →  Na⁺  +  BrO₄⁻    i = 2

LiCN  →  Li⁺  +  CN⁻         i = 2

KNO2  →  K⁺  +  NO₂⁻        i = 2

The biggest i would have the biggest boiling point, then B is the right answer, ammonium phosphate.

You count the i, with the moles of ions, you dissociate from the salt.

Answer: The molecular formula will be [tex]C_6H_6O[/tex]

Explanation:

Molecular formula is the chemical formula which depicts the actual number of atoms of each element present in the compound.  

Empirical formula is the simplest chemical formula which depicts the whole number of atoms of each element present in the compound.

The empirical formula is [tex]C_6H_6O[/tex]

The empirical weight of [tex]C_6H_6O[/tex] = 6(12)+6(1)+1(16) = 94 g.

The molecular weight = [tex]2\times \text{vapour density}=2\times 47=94[/tex]

Now we have to calculate the molecular formula.

[tex]n=\frac{\text{Molecular weight}}{\text{Equivalent weight}}=\frac{94}{94}=1[/tex]

The molecular formula will be=[tex]1\times C_6H_6O=C_6H_6O[/tex]
