Valence electrons in a covalent bond are shared among the bonded atoms.
Answer:
false
Explanation:
when heat is added to atoms, the molecules vibrate more quickly, because it increases the heat energy, which in turn, increases the particle movement
Answer:
Negative
Explanation:
For a solution to form, the change in Gibbs free energy must be negative for dissolving. When a solute dissolves in a saturated solution, ΔH(enthalpy change) is negative and ΔS(entropy change) is positive, giving rise to a large negative ΔG(change in gibbs free energy) and a very high solubility.
