Answer: E
Explanation:
The lattice energy is the energy change when one mole of a crystal is formed from its components ions in its gaseous sate
Therefore lattice energy = heat of Sublimation+ ionization energy +electron affinity-(heat of formation)
Therefore lattice Energy = 109 +495 -328 +570.
Lattice energy = --923kjmol-1
I think B or D because an eye obviously doesn't have a lense, mirror..maybe sorry for not giving u straight forward response
It is a compound because a compound is two or more different elements chemically combined.
Answer:An atom
Explanation:
Because molecules more spread out and have things that connnect them and are not bunched up togoether
And Atoms are all packed up like in the picture
Hope this helps!:D
