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



The answer is *strength*

Answers

Answer 1
Answer:

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.
Answer 2
Answer:

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.

Given the reaction: Mg(s) + 2 AgNO3(aq) → Mg(NO3)2(aq) + 2 Ag(s) Which type of reaction is represented?

Answers

The reaction: Mg(s) + 2 AgNO3(aq) → Mg(NO3)2(aq) + 2 Ag(s) is represents - single replacement reaction.

A single replacement reaction is one in which a more reactive element displaces a less reactive element from its salt solution. Magnesium can easily lose electrons as compared to silver and result in the formation of magnesium nitrate and silver.

  • A double displacement reaction is a chemical reaction in which ion exchange takes place.
  • A synthesis reaction is a chemical reaction in which two reactants combine to give a single product.
  • Decomposition is a chemical reaction in which one substance decomposes to give two or more than two products.

Thus, the reaction represents - single replacement reaction.

Can anyone explain this?

Answers

I can tell you that the first five elements of the periodic table does not obey the octet rule. The only reason for that is because they are trying to be like their closest noble gas which will be helium in this case.
