Answer:

Lattice energy is <em>the energy required to convert a mole of ionic solid into its constituent ions in the gas phase</em>

Explanation:

Lattice energy is usually calculated by the Born-Haber cycle, from the affinity energies and sublimation ethalphy values. It is used as an estimation of the ionic energy strength between the ions in an ionic compound.

It is defined as the energy needed to broke 1 mol of a given ionic compound into its ions in the gaseous state. For example, the lattice energy for sodium chloride (NaCl) is the energy required to separate 1 mol of solid ionic compound (NaCl(s)) and produce the sodium and chlorine ions in the gas phase: Na⁺(g) and Cl⁻(g).

To convert from mass of X to liters of Y in any stoichiometry problem, the following steps must be followed
gizmo_the_mogwai [7]

Answer:

A. mass X to moles X to moles Y to liters Y

Explanation:

Remember: moles are the great converter. They're basically just a made-up concept meant to facilitate conversions!

Starting with mass X, you must then convert to moles X.

Once you have moles X, convert  moles Y. Think of a chemical equation: the mole ratios are the coefficients!

Once you have moles Y, all you have to do is convert to liters Y. You can do this with the molarity equation M = mol/L, or if it's a gas at STP you know the conversion!

there are 3 isotopes of the element Gz: Gz-80,Gz-81,Gz-83. the average atomic mass of Gz is 82.74. what is the most abundant iso
Romashka-Z-Leto [24]

The most abundant isotope is Gz-83 because the average atomic mass of Gz is closer to 83.

The average atomic mass is defined as the weigthed mean of the isotopes.

The mass of the isotopes is 80, 81 and 83 uma, respectively.

As the average atomic mass (82.74uma) is closer to the atomic mass of Gz-83 than the mass of the other isotopes, you can interpretate that the most abundant isotope is Gz-83.

The number of protons in a neutral atom is balanced by an equal number of
anastassius [24]
There would be an equal amounts of ELECTRONS.

In order for the atom to be neutral it would imply that the number of protons (positive particles) and the number of electrons (negative particles) are equal since the neutrons are without charge.
