The phase that occurs beyond the critical point is:

A. Liquid

B. Solid

C. Gas

D. All of the above

Answers

Answer 1

Answer:

C.  Gas

Explanation:

A supercritical fluid occurs beyond the temperature of  critical point, wherein the state  matter transitions from liquid to gaseous phase interchangeably. Whereas, triple point occurs when all three states of matter: solid, liquid nd gas; coexist.

Hence the answer to the question is Gaseous phase/

A compound was analyzed and found to contain the following percent composition: 2.056% hydrogen, 32.69% S, and 65.26% oxygen. Calculate the empirical formula.

Answers

Answer:

H2SO4

Explanation:

Firstly,

2.056% hydrogen = 2.056g of H

32.69% Sulphur = 32.69g of S

65.26% oxygen = 65.26g of O

Next, we convert each mass into moles by dividing by their respective molar mass:

H = 1, S = 32, O = 16

H = 2.056/1 = 2.056mol

S = 32.69/32 = 1.021mol

O = 65.26/16 = 4.078mol

Next, we divide each mole value by the smallest mole value (1.021)

H = 2.056/1.021 = 2.01

S = 1.021/1.021 = 1

O = 4.078/1.021 = 3.99

Approximately the ratio of H to S to O is 2:1:4, hence, the empirical formula for H, S and O is H2SO4.

The empirical formula of a chemical compound is the simplest whole-number ratio of atoms present in a compound

The correct answer of the following is [tex]H_2SO_4[/tex]

The data is given as follows:-

2.056% hydrogen = 2.056g of H 32.69% Sulphur = 32.69g of S65.26% oxygen = 65.26g of O

We have to find the moles in the reaction.

The mas of the element is as follows:-

H = 1S = 32O = 16

After solving the equation we get

[tex]H = \frac{2.056}{1} = 2.056mol\\\\S = \frac{32.69}{32} = 1.021mol\\\\O = \frac{65.26}{16} = 4.078mol[/tex]

Next, we divide each mole value by the smallest mole value (1.021)

[tex]H = \frac{2.056}{1.021} = 2.01\\\\S = \frac{1.021}{1.021} = 1\\\\O = \frac{4.078}{1.021} = 3.99[/tex]

The ratio of H to S to O is 2:1:4,

Hence, the empirical formula for H, S, and O is [tex]H_2SO_4.[/tex]

a container with a volume of 2.5L contains air at a pressure of 0.5 atm. if the volume is reduced to 1.5L at constant temperature, what will be the resulting pressure of the air inside

Answers

Answer:

Final pressure of the air inside is 0.83atm

Explanation:

Boyle's law is the gas law that relates the change in volume when pressure change at constant temperature and vice versa. The equation is:

P₁V₁ = P₂V₂

Where P is pressure and V is volume of 1, initial state and 2, final state of the gas

Replacing:

P₁ = 0.5atm

V₁ = 2.5L

P₂ = ?

V₂ = 1.5L

P₁V₁ = P₂V₂

0.5atm*2.5L = P₂*1.5L

0.83atm = P₂

Final pressure of the air inside is 0.83atm

If 34.0g of As react with excess NaOH at STP, what volume of H2 will be produced in liters?


If you can answer this question quickly, I will mark you brainliest, I'm stumped to be honest.

Answers

The volume of H₂ : = 15.2208 L

Further explanation

Given

Reaction

2 As (s) + 6 NaOH (aq) → 2 Na₃AsO₃ (s) + 3 H₂ (g)

34.0g of As

Required

The volume of H₂ at STP

Solution

mol As (Ar = 75 g/mol) :

= mass : Ar

= 34 g : 75 g/mol

= 0.453 mol

From the equation, mol ratio As : H₂ = 2 : 3, so mol H₂ :

=3/2 x mol As

=3/2 x 0.453

= 0.6795

At STP, 1 mol = 22.4 L, so :

= 0.6795 x 22.4 L

= 15.2208 L

From the following elements: lithium, beryllium, and fluorine, predict which
one will have the largest second ionisation energy. Explain your answer.

Answers

Answer:

The element that has the largest second ionization energy is;

Lithium, Li

Explanation:

The given elements and their positions on the periodic table are;

1) Lithium is located in group 1, period 2 position on the periodic table

2) Beryllium is located in group 2, period 2 position on the periodic table

3) Fluorine is located in group 17, and period 2 position on the periodic table

The first ionization energy of the atoms in the periodic table increases across the periods from left to right and also increases from bottom to the top within a group

However  for the second ionization energy, which is the energy required to remove an electron from an atom that has one less electron, we have;

The electron configuration of the given of ions that take part in the reaction for the removal of the second ionization energy are;

Li⁺ = [He} 2s⁺

Therefore, the second ionization energy is the removal of an electron from the stable duplet of the helium atom (the core of the lithium atom) which require about 7297 kJ/mol

For beryllium, we have;

Be⁺ = [He]2S¹⁺

Therefore, the second ionization requires the removal of the remaining one electron in the valence shell, which will then lead to the remaining structure of the stable helium core and therefore, the second ionization energy of beryllium is about 1757 kJ/mol, which is low compared to helium

For fluorine, we have;

F⁺ = [He] 2s² 2p⁴⁺

Therefore, the second ionization of fluorine remains high due to the increased attraction of the positively charged fluorine ion for electrons than electrically neutral fluorine atom that has equal number of protons and electrons such that the second ionization energy of fluorine is higher than the first ionization energy and is about 3357 kJ/mol

Therefore, the element that has the largest second ionization energy is lithium, Li.

C6H10CI2
C6H8CI2
C3H5CI
C4H4CI
C8H8CI2​

Answers

Answer:

C6H10Cl2

Explanation:

Convert mass % to mass

100g of the compound contains from each elements: 46,3g Cl; 47,05g C and 6,63g H

Molar mass

Cl = 35.5 g/mol

C = 12 g/mol

H = 1 g/mol

Find the number of moles:

Chlorine: 46.4g /35.5g/mol = 1,3 moles

Carbon: 47,05g/12 g/mol = 3,92 moles

hydrogen: 6,63g/1g/mol = 6,63 moles

Molar fraction:

Cl = 1,30/ 1,30 = 1

C = 3,92/ 1,30 = 3,01

H = 6,63/ 1.30 = 5,01

C3H5Cl = 76,5 g/ mol x 2  = 153 g/ mol

So multiply the molecular formula by two = C6H10Cl2

Answers

Answer:

2CH4 ------> 3H2 + C2H2

Explanation:

The law of conservation of mass states that atoms can neither be created nor destroyed in a chemical reaction.

The implication of this law is that the number of atoms of each element on the reactant side must be equal to the number of atoms of each element on the product side.

This law is only obeyed by the reaction, 2CH4 ------> 3H2 + C2H2

There were eight atoms of H on the left hand side as well as the right and side of the reaction equation. There were two atoms of C on both the left and right hand sides of the reaction equation respectively. Hence, the law was obeyed here.

Number of molecules = ?

Solution:

Avogadro number:

The number 6.022 × 10²³ is called Avogadro number.  

It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.  

For example,

18 g of water = 1 mole = 6.022 × 10²³ molecules of water

1.008 g of hydrogen = 1 mole = 6.022 × 10²³ atoms of hydrogen

Number of molecules of silver:

1 mole contain 6.022 × 10²³ molecules

0.89 mol  ×  6.022 × 10²³ molecules /1 mol

5.36 × 10²³ molecules

When a metal replaces another metal in solution, we say such a reaction has undergone a single displacement reaction.

In such a reaction, metal higher up in the activity series replaces another one due to their position.

To known the metal or metals that will replace the given copper, we need to reference the activity series of metals.

Every metal higher than copper in the series will displace copper from the solution.

So, there metals are: potassium, sodium, lithium, barium, strontium etc.
