Question

section on adhesion. Calculate the molarity of each solution you generated and record the molarity in Data Table 1. Question: How long did it take? Question: Which is the solvent? Question: Which is the solute? Data Table 1: NaCl solution molarity concentrations Solution # Grams NaCl added Molarity (M) #1 5 #2 10 Hydrogen Bonding, Expansion on Freezing, Specific Heat, Evaporative Cooling Figure 3: 5 H-Bonded Water Molecules Water tends to "hang out" in groups of five molecules. This is due to the intramolecular hydrogen bonding that occurs between different water molecules. Question: How many hydrogen bonds are present in Figure 3 (shown above)? Question: What properties of water molecule allow hydrogen bonds to form? Question: Water expands when it freezes, forming a lattice type structure as shown in the Figure 4. Using information, explain why ice floats. Figure 4: Lattice formed by water molecules in ice.

Water tends to "hang out" in groups of five molecules. This is due to the intramolecular hydrogen
bonding that occurs between different water molecules.
Question: How many hydrogen bonds are present in
Figure 3 (shown above)? Question: What properties of
water molecule allow hydrogen bonds to form?
Question: Water expands when it freezes, forming a
lattice type structure as shown in the Figure 4. Using
information, explain why ice floats.
