Answer: 
Explanation:
Lattice energy : It is defined energy released when ions combine together in a gaseous phase to form a compound. it is energy possessed by the crystal lattice of a compound. Denoted by symbol 
.
, energy is absorbed while forming of the lattice
, energy is release while forming of the lattice
One mole of sodium ion when combines with one mole chloride ion release 786 kJ of energy.
Answer:
C: The Fe is not balanced
Explanation:
The reaction expression is given as:
Fe₂O₃ + 3H₂ → Fe + 3H₂O
The problem here is to find the specie that is not balanced.
Number of moles
Specie Reactant Product
Fe 2 1
O 3 3
H 6 6
So, we see that Fe is not balanced.
An ionic bond will most likely form
covalent bonds form when an electron is shared and ionic bonds form when an electron is transferred
