Answer:
The distance the plane flies.
Explanation:
This is the dependent (outcome) variable because it is changing depending on the number of paper clips that are added to the plane.
Oxygen is more ELECTRONEGATIVE than Hydrogen, which means that the electrons in the atom are coaxed more toward the Central Oxygen atom. Because of this, the charge is not evenly distributed among the molecule, causing it to have positive and negative sides. This is what we call a POLAR molecule.

Answer is: solution is acidic, because pH value is less than 7,46.
The Kw (the ionic product for water) at 0°C is 0,12·10⁻¹⁴ mol²/dm⁶.
Kw = [H⁺] · [OH⁻<span>].
</span>[H⁺] = [OH⁻] = √0,12·10⁻¹⁴ mol²/dm⁶.
[H⁺] = [OH⁻] = 3,5·10⁻⁸ mol/L.
pH = -log[H⁺].
pH = -log(3,5·10⁻⁸ mol/L).
pH = 7,46; neutral solution on 0°C.
Ponds are most likely to dry up
