Answer:
no H2O molecules are produced:)
Explanation:
Answer:
condensation
Explanation:
when gases change to liqud it condenses.This occurs when the temperature is lowered
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
The answer is 2.138 g of H2
