Consider the equation: 2NO2= N2O4. Using ONLY the information given by the equation which of the following changes would increase the molar concentration at equilibrium of the product N2O4?

Answers

Answer 1

Answer: By the way I love science. So there are two moles of NO2(g) with an N204(g). Decreasing most moles. So your answer would be "Pressure Increase" Hope his helps.

Federalism and Separation of Powers policies seek for decentralised the power and avoid tyranny.

Explanation:

Separation of Powers, according to Montesquieu, is a policy that allow the country to have democracy, because this separation is constituted by three main autonomous powers: judicial, executive and legislative. Each institution can judge others, so this way whole nation power is not concentrated in one point.

In this way, Federalism is alike, because this policy is about having a central government (Federal), and regional governments (States) in a whole political system. So, each regional government has their own rules and freedom to their jurisdiction.

Lewis structures are used to represent ___.

Answers

How many molecules are in 165 g of carbon dioxide?

Answers

Answer: $22.6 * 10^(23)$ molecules

Explanation:

To calculate the moles, we use the equation:

$\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}$

For $CO_2$

Given mass= 165 g

Molar mass of $CO_2$ = 44 g/mol

Putting values in above equation, we get:

$\text{Moles of}CO_2 =(165g)/(44g/mol)=3.75mol$

According to avogadro's law, 1 mole of every substance weighs equal to the molecular mass and contains avogadro's number $6.023* 10^(23)$ of particles.

1 mole of $CO_2$ contains = $6.023* 10^(23)$ molecules of $CO_2$

Thus 3.75 moles $CO_2$ contains = $(6.023* 10^(23))/(1)* 3.75=22.6 * 10^(23)$ molecules of $CO_2$

Thus there will be $22.6 * 10^(23)$ molecules of $CO_2$

The molar mass of CO2 is 44 grams per mole.

165 grams / 44 grams per mole of CO2 = 3.75 moles CO2

Using Avogadro’s law where 1 mole of substance equals 6.023 x 10^23 molecules

3.75 moles CO2 (6.023 x 10^23 molecules /mole) = 2.26 x 10^24 molecules CO2

Lattice energy is an estimate bond of the bond:-conductivity
-group
-length
-strength

The answer is *strength*

Answers

Answer:

Strength

Explanation:

Lattice energy is the energy needed to remove one mole of ionic substance to its gaseous ion.

The lattice energy is used to determine the strength of a substance.

Lattice energy increases as the size of an ion decreases.
It decreases as the ion size increases.
This quantity is often determined using electrostatics method in the laboratory
The lattice energy is used to break an ionic solid to form a gaseous compound.

Lattice energy is an estimate of the strength of the bond because lattice energy is a measure of the strength of the electrostatic forces holding ions together in an ionic compound's crystal lattice. So the correct option is D.

D. strength

Lattice energy is the energy required to completely separate one mole of an ionic compound into its individual gaseous ions. In other words, it measures the strength of the forces that hold the ions together in the crystal lattice. Lattice energy is typically expressed in energy units per mole, such as kilojoules per mole (kJ/mol).

Factors Influencing Lattice Energy:

1. Charge of Ions: Greater charge on ions leads to stronger attractions and higher lattice energy.

2. Ionic Radius: Smaller ionic radii lead to higher lattice energy. When ions are smaller, they can get closer to each other in the crystal lattice, resulting in stronger electrostatic attractions.

3. Distance between Ions: Lattice energy increases as the distance between ions decreases. Closer ions experience stronger attractions.

4. Electron Configuration: The arrangement of electrons affects the effective nuclear charge felt by the ions. Ions with more stable electron configurations (e.g., noble gas configurations) have higher lattice energies.

Lattice energy plays a crucial role in determining the stability and properties of ionic compounds. It influences properties such as melting and boiling points, hardness, solubility, and the overall stability of the compound. Compounds with higher lattice energies tend to have higher melting points and are less likely to dissociate into ions in solution.

Therefore, lattice energy is a measure of the strength of the electrostatic forces holding ions together in an ionic compound's crystal lattice. It's influenced by factors such as ion charges, ionic radii, and distance between ions.

Help please I don’t know

Answers

Answer:

I don't EXACTLY know but hopefully the description below helps you find the answer!

Ionic bonding is a type of chemical bond in which valence electrons are lost from one atom and gained by another. This exchange results in a more stable, noble gas electronic configuration for both atoms involved. An ionic bond is based on attractive electrostatic forces between two ions of opposite charge.
