A rocks or a desk would be molecular solid. Ex. gas is not a molecular solid.
Because punnet squares are based off probability.
<span>1 drop is approximately 0.05mL. Since 0.500L of 0.550M NH4Cl contains 0.275mol of substance (calculated by using c=n/V formula), equal amount of substance of NH3 is needed to neutralize this solution (since pH of 7 is neutral solution). Thus, we need 0.0275L of NH3, i.e. around 550 drops.</span>
A.the force between two non polar molecules are stronger than the force between positive ions and freely moving electrons
