What is lattice heat capacity?

Definitions of lattice energy: * The energy released when one mole of a crystal is formed from gaseous * The energy for the reaction of the infinitely separated ions to give the solid. It measures the electrostatic interaction between the * The energy given off when oppositely charged ions in the gas phase come together to form a solid. For example, the energy given off in the following reaction: Na + (g) + Cl - (g) NaCl(s) * Lattice energy deals primarily with metals. The lattice energy, or lattice enthalpy, of an ionic solid is a measure of the strength of bonds in that ionic compound. It is given the symbol U and is equivalent to the amount of energy required to separate a solid ionic compound into gaseous ions. energy the lattice energy of an ionic solid is a measure of the strength of bods in that ionic compound. it is usually defined as the enthalpy of formation of ionic compound from the gaseous ions and as such is invariably exothermic

What happens to the stability of atoms when they form covalent?

The formtion of chemical compounds generally involves heat being given off so energy is required to "break" the compound up back nto its elments. This s true for the all of the types of bonds, each one increases the overall stability.Bonds have bond energy - the energy required to break them.

Is energy given out when elements are formed from a compound?

In almost all cases, it requires energy to break a compound down to its constituent elements. There are, however, some cases in which the decay of a compound into its constituent elements would release energy. Platinum hexafluoride would be an example.

What is the energy required to increase the surface area of a liquid by a given amount?

Surface Tention

Is energy given off or required when chemical bonds are formed?

Yes because if you put something together the energy will change. Or if you put a chemical ( Any kind) It would change the energy that it 2was before. What kind of form of energy is it though!

How can you predict lattice energy?

An estimate of the strength of the bonds in an ionic compound can be obtained by measuring the lattice energy of the compound, which is the energy given off when oppositely charged ions in the gas phase come together to form a solid.

Energy required to melt a solid into a liquid?

Energy is given off when cooling from a liquid to a solid. How much depends on the elements involved and the amount.

How do you separate copper from copper sulfate?

Given its an ionic compound, you could probably just disassociate it with water. Or you could react it with a more electrophilic metal than Copper is.

A great deal of energy is produced when an ionic compound is formed?

False. Formation of a compound is usually exothermic because a Noble Gas configuration forms around each atom. Therefore energy is given off during formation, and the atoms in the compound are more stable.

What is metabolic load in gene expression?

The metabolic load of a given gene is the amount of energy required to express it within a cell.

Process of vaporization require an input of energy?

Yes, the process of vaporization does require an input of energy. The energy is required to break the intermolecular forces of a given substance. The intermolecular forces is usually very strong.

What do you call the amount of energy required to change a liquid to a gas?

Latent Heat of Evaporation, or Evaporation Enthalpy. It is given in units of energy over unit of mass, i.e., KJ/Kg.
