Answers

because of atom don't put that as an answer

Explanation:

i need point to do finals

Answer 2

The different behavior of particles in solids and gases, including the intermolecular forces and kinetic energy, leads to solids filling only part of a closed jar while the same mass of a gas fills the whole jar. A solid fills only part of a closed jar, while the same mass of a gas fills the whole jar due to the differences in the behavior of particles in each state of matter.

1. Solid: In a solid, the particles are tightly packed and held in a fixed position. They have a definite shape and volume. The intermolecular forces between the particles are strong, preventing them from moving freely. As a result, solids occupy a specific amount of space within a container.

2. Gas: In a gas, the particles are spread out and move freely. They have no definite shape or volume. The intermolecular forces between the particles are weak, allowing them to move and fill the available space. As a result, gases can expand to fill the entire volume of a container.

When the same mass of a gas and a solid are placed in a closed jar, the gas particles have higher kinetic energy and are more mobile. They collide with each other and the walls of the container, exerting pressure and spreading out to occupy the entire space. Since the intermolecular forces are weak, the gas particles are not constrained by a fixed arrangement.

can someone please explain how to find an emperical formula given mass not percentage?​

Answers

Answer:

1. Get the mass of each element by assuming a certain overall mass for the sample (100 g is a good mass to assume when working with percentages). ...

2. Convert the mass of each element to moles. ...

3. Find the ratio of the moles of each element. ..

4. Use the mole ratio to write the empirical fomula

Answer:

Multiply each result by the given mass.

Explanation:

Hi!

In order to find percent/mass composition you would

1. write the formula

2. calculate the molar mass for each equation

3. add all the masses to get the compound molar mass

4. divide each molar mass by the total mass

and then for mass composition, you would multiple eachy result by the given mass.

For example;

Calculate the number of grams of gold in 89.6 grams of gold(1) perchlorate.

Your formula would be AuClo4

Au : 196.96 x 1

Cl: 35.4 x 1

O: 16 x 4

Add the masses together to get 296.5 g/mol

Lets say we're looking for Oxygen. You would take what you got (16 x 4) and divide it by the total mass. 64/296.5

This would equal 0.215. Instead of multiplying this by 100 like you would for percent, for mass you would multiply by what is given. in this instance it is 89.6.

0.215 x 89.6 = 19

But the question is asking for gold,

197/296

= 0.664 x 89.6

= 59.5

Your answer would be 59.5 grams Au

when an electron is acquired by a neutral atom, the energy change is called

Answers

Answer:

when an electron is acquired by a neutron atom, the energy change is called its electron affinity

When an electron is added to a neutral atom to create a negative ion, the energy of the atom changes (in kJ/mole). This is how electron affinity is defined. Alternatively put, the possibility of the neutral atom receiving an electron.

What is electron affinity ?

The amount of energy released when an electron binds to a neutral atom or molecule in the gaseous state to produce an anion is known as the electron affinity of an atom or molecule.

Although there is a slight distinction between the two, electron gain enthalpy is occasionally also referred to as electron affinity. The amount of energy released when an electron is added to a single gaseous atom is known as the electron gain enthalpy.

The amount of energy released when an atom receives an additional electron is known as its electron affinity. The gaseous state is when electron affinities are measured. On the periodic table, electron affinities tend to shift from negative to positive as we move from left to right.

Thus, when an electron is acquired by a neutral atom, the energy change is called as electron affinity.

Answers

Answer:

D (But as a heads up, you wrote barium instead of Bromine)

Explanation:

The Potassium atom will lose an electron since its valence shell only has one, while Bromine has 7 electrons in its valence shell. Potassium wants to get rid of its one electron, Bromine wants to gain that one electron to get a full shell.

Potassium will become a CATION with a positive charge (since it lost an electron), Bromine will become an ANION with a negative charge (since it gained an electron)

1. In drawing Lewis structures, a single line (single bond) between two elements represents: ? a shared electron B. ? B 2 a shared pair of electrons c. ? an octet of electrons D. ? an unshared pair of electrons​

Answers

Answer:

B a shared pair of electrons (2)

Explanation:

In Lewis structures, a single line represents a single pair of electrons. This means that the elements share 2 electrons or one pair of electrons

Hope this helps!

The shared electrons behave as if they belong to both atoms in the bond and bind the two atoms together to form a molecule. The shared electrons are typically depicted as a line (—) connecting the bonded atoms. (A line in a Lewis structure represents two electrons. Therefore, option A is correct.

What is lewis structure ?

Lewis structures, also known as Lewis dot formulas, Lewis dot structures, electron dot structures, or Lewis electron dot structures, are diagrams that depict the bonding between atoms in a molecule as well as any lone pairs of electrons that may exist.

A Lewis structure is based on the octet rule, which states that atoms share electrons in order for each atom to have eight electrons in its outer shell. An oxygen atom, for example, has six electrons in its outer shell.

Gilbert N. Lewis, who introduced the Lewis structure in his 1916 article The Atom and the Molecule, was named after it. Lewis structures expand on the electron dot diagram concept by adding lines between atoms to represent shared pairs.

Thus, option A is correct.

M - Molarity.

V - Volume (in mili liters/ml/ in this case).

The formula is stated as:

M1 * V1 = M2 * V2

Given- Required

M1 = 0.125M V1 = 265ml M2 = ?

V2 = 186ml

Plug these values into the formula above and divide V2 to get M2.

It takes 60 mL of 0.20 M of sodium hydroxide (NaOH) to neutralize 25 mL of carbonic acid (H2CO3) for the following chemical reaction:


2 NaOH + H2CO3 → Na2CO3 + 2 H2O


The concentration of the carbonic acid is _____.

Answers

It requires 60 mL of 0.20 M sodium hydroxide [tex](NaOH)[/tex] to neutralize 25 mL of carbonic acid [tex](H_2CO_3)[/tex], hence the carbonate ions concentration is [tex]0.24M[/tex].

Given:

Reaction:

[tex]\to \bold{2NaOH + H_2CO_3 \to Na_2CO_3 + 2H_20 }[/tex]

[tex]NaOH[/tex] volume [tex](V_B) = 60 \ ml[/tex]  

[tex]H_2CO_3[/tex] Volume [tex](V_A) = 25\ ml[/tex]  

[tex]NaOH[/tex] Molarity [tex](C_B) = 0.20\ M[/tex]

[tex]H_2CO_3[/tex] moles [tex](n_A) = 1[/tex]

[tex]NaOH[/tex] moles [tex](n_B) = 2[/tex]

To find:

[tex]H_2CO_3[/tex] Molarity [tex](C_A) =?[/tex]

Solution:

Using the neutralization reaction:  

[tex]\to \frac{C_AV_A}{C_BV_B} =\frac{n_A}{n_B} \\\\[/tex]

[tex]\to C_B = 0.2\ M \\\\ \to n_A = 1 \\\\ \to n_B = 2 \\\\ \to V_B = 60\ ml \\\\ \to V_A = 25\ ml[/tex]

Calculating the [tex]C_A[/tex]:

 [tex]\to \frac{C_A \times 25}{0.2 \times 60} =\frac{1}{2} \\\\\to C_A =\frac{1 \times 0.2 \times 60}{2 \times 25} \\\\\to C_A =\frac{1 \times 2 \times 12}{2 \times 5 \times 10} \\\\ \to C_A =\frac{ 12}{ 5 \times 10} \\\\\to C_A = \frac{6}{5 \times 5} \\\\\to C_A = \frac{6}{25} \\\\\to C_A=0.24\ M[/tex]

The concentration of carbonic acid( H₂CO₃) is 0.24 M.

The given reaction:

2 NaOH + H₂CO₃ → Na₂CO₃ + 2H₂O

Volume of NaOH  = 60mL

Volume of H₂CO₃ = 25 mL

Molarity of NaOH= 0.20M

To find:

Molarity of H₂CO₃=?

2 moles of NaOH and 1 mol of H₂CO₃ reacts to give 1 mol of Na₂CO₃.

Using the neutralization reaction:  

Consider A to be NaOH and B to be  H₂CO₃

[tex]\frac{\text{Number of moles of A}}{\text{Number of moles of B}} =\frac{\text{Molarity of A*Volume of A}}{\text{Molarity of B*Volume of B}}[/tex]

On substituting the values in order to calculate molarity of H₂CO₃:

[tex]\text{Molarity of B}=\frac{1*0.2*60}{2*25} \\\\\text{Molarity of B}=0.24M[/tex]
