Question

Need to know answers to A, B, C and D.

A. Discuss the why polar covalent bonds between oxygen and hydrogen are so significant to thr propeeties of water.

B. identify the physical properties of water that make it physiologically important.

C. Discuss the significance of Hydrogen Bonds between water Molecules, which have to do sith high surface tension, high specific heat, etc.

D. why can you grow cherries next to lake michiganc but typicallt not in the interior of michigan?

Answer 1

A. One of the important properties of water is its composition of polar molecules. The water molecules contains two hydrogen atoms and one oxygen atom to form polar covalent bonds. As oxygen is more electronegative than hydrogen, it generates the charges of water. Presence of hydrogen within the water molecules causes hydrogen bonding by giving polarity, which makes water a good solvent and gives ability to stick to itself and also to other substances. So, the polar covalent bonds between hydrogen and oxygen are significant to the properties of water.

B. The physical properties of water that make it physiologically important are its polarity (two hydrogen atoms and one oxygen atom within water molecule forms covalent bond), cohesion (makes water molecules attracted to each other), adhesion (tendency of water molecules to attract or stick to other substances), surface tension (property of a water molecule to resist external force), high specific heat (amount of heat required to raise the temperature) and evaporative cooling, charge of water molecules due to more electronegativity of oxygen than hydrogen. These physical properties of water makes it physiologically important.

C. Hydrogen bonds between water molecules are significant because when heat is absorbed, hydrogen molecules between water gets broken and the water molecules can move freely. Also when the temperature of water decreases, hydrogen bonds are formed and releases considerable amount of energy. So, hydrogen bonds between water molecules are significant.

D. The Lake Michigan is provided ideal for growing cherries as it tempers Arctic winds in winter and cold the orchards in summer. So, the cherries are grown next to the Lake Michigan but not inside it. In the Lake Michigan, all the cold air sits on the bottom so, cherries are grown on the tops.
