Which property is best to use when determining the strength of an ionic bond in a solid?
lattice energy
conductivity
hardness
solubility

Option (a) is the correct answer.

Explanation:

Lattice energy is defined as the heat of formation of oppositely charged ions in the gaseous phase which combines to form an ionic solid.

Hence, stronger is the force of attraction between the oppositely charged ions stronger will be the strength of ionic solid.

Whereas conductivity is the ability of a substance to let current pass through it.

Hardness is the property of a substance to resist any kind of deformation.

Solubility is the property of a substance to completely dissolve into a solution.

Thus, we can conclude that lattice energy is the property which is best to use when determining the strength of an ionic bond in a solid.

linda: 3 ; laura: 15

step-by-step explanation:

note that linda + laura's age is 18, and that linda is 12 years younger than her sister.

let "linda" = x , "laura" = y:

x + y = 18

x = y - 12

first, plug in y - 12 for x in the first equation:

(y - 12) + y = 18

simplify.

2y - 12 = 18

isolate the variable (y). note the equal sign, what you do to one side, you do to the other. do the opposite of pemdas. first add, then divide.

2y - 12 (+12) = 18 (+12)

2y = 18 + 12

2y = 30

(2y)/2 = (30)/2

y = 30/2

y = 15

next, plug in 15 for y in the second equation (the other equation would work too).

x = y - 12

x = (15) - 12

x = 3

linda's age is 3, laura's age is 15.
