AMAZING, WILD, WONDERFUL WATER (And organisms that use it) dict I hope that after the lecture on water and this lab on water you will never be able to drink a glass of water again without feeling amazed. Understand -no water...no life. This is something you probably know on the level of dehydration of a human being...but do you know all of the amazing properties of water and why they sustain and contribute to life on earth? Water is so great. Three-fourths of the earth's surface is submerged in it. Cells are surrounded by it and mostly made up of it. Much of the search for life beyond earth is based on the identification of the existence of water. Water has a unique structure and remarkable emergent properties. Water is involved in the process of transpiration, which brings water from a root to the top of a tree as tall as a giant sequoia. Water is an amazing moderator of temperature. Water as ice has a unique property that sustains life below the ice! Water is the most versatile solvent we have! WOW! Are you a believer? From what you wil/have learned in lecture about water, answer a few preliminary questions 1. In the H2O molecule, which atom is the most electronegative? ten Because of the electronegativity differences of the atoms in the water molecule what type of covalent bond is formed between the atoms? 2. 3. Define the type of covalent bond you named in question 2 4. What effect does this type of bond have on each of the atoms of the H20 molecule? What resulting bonds can be formed between water molecules because of this effect? 5. Explain why two water molecules would not associate as you see in this image? 6. If oxygen and hydrogen had equal electronegativity, what would be lost in water? The covalent bunds of water moie c ogen on 39 41

Explanation / Answer

Q2 ANSWER) Hydrogen bonds. Since the atoms in water form a polar covalent bond, the positive.  This attraction forms the hydrogen bond.

Q5 ANSWER) As per the question the hydrogen form both of hydrogen molecules lie on the same place and hence there will maximum distortion or repulsion because of postive charge between H-H . Hence the two water molecules would not associate or the above structure is not possible.
