Which property is best to use when determining the strength of an ionic bond in a solid? lattice energy conductivity hardness so
Leona [35]

The property best used when determining the strength of an ionic bond in a solid is:

LATTICE ENERGY

The lattice energy is the energy released during the deposition of gaseous ions of opposite charges. Deposition is the transformation of gas to solid.

Explanation:

The main types of solids are ionic, molecular, covalent, and hard. Ionic solids consist of absolutely and negatively energized ions held concurrently by electrostatic forces; the power of the bonding is indicated in the lattice energy. Ionic solids manage to have high melting points and are fairly hard. lattie energy is a stratagem of the energy received in the crystal lattice of a compound, similar to the energy that would be delivered if the element ions were produced together from infinity.

Chemist preformed Reaction of solid magnesium burning and found that the mass of the magnesium oxide what is greater than the ma
tankabanditka [31]

Answer:

The magnesium reacted with the oxygen in the air.

Explanation:

For argument’s sake, let’s say that the mass of magnesium oxide was 3 g and that of the oxide was 5 g.  

The reaction was

            magnesium + oxygen ⟶ magnesium oxide

Mass:           3 g                                          5 g

Mass of oxygen = 5 g – 3 g = 2 g

The 3 g of magnesium must have combined with 2 g of oxygen to form 5 g of magnesium oxide.

In a previous problem, the empirical formula of a compound of phosphorus and oxygen was found to be p2o5. experimentation shows
agasfer [191]
The empirical formula for the compound is - P₂O₅
the empirical formula is the simplest ratio of whole numbers of components in a compound.
molecular formula is the actual ratio of components in a compound.
we have to first find the number of empirical units in the molecular formula 
molecular mass - 283.89 g/mol
mass of empirical formula - 283.8 g
number of empirical units - 283.89 g/mol / 283.8 g
number of empirical units - 1.000 
therefore empirical formula = molecular formula 
molecular formula - P₂O₅
