| Be able to describe or identify how the electronegativity of oxygen produces a partial charge differential (polarity) across the water molecule part 1 | Due to the higher electronegativity of oxygen electrons are pulled more towards the oxygen atom than towards the hydrogen atom in the water molecule. Between different molecules of h2o due to presence of a slight+charge over H & a slight-charge over O...

| Be able to identify how the polarity leads to hydrogen bonding and cohesiveness | The dipole interaction water has forms hydrogen bonds. Positive side of one molecule is attracted to the positive side of another. The high surface tension caused between hydrogen bonds creates cohesion, attaching to itself.

| Be able to identify how polarity of water affects water's ability as a solvent | Water is capable of dissolving a variety of different substances, which is why it is such a good solvent. And, water is called the "universal solvent" because it dissolves more substances than any other liquid.

| Be able to identify how hydrogen bonding leads to waters resistance to vaporization | Water is very resistant to changes in its KE (temperature) due to restraints of hydrogen bonds. More energy is needed to break it, meaning much more heat=vaporization of water needs a lot of energy to be complet

| Be able to describe or identify how the electronegativity of oxygen produces a partial charge differential (polarity) across the water molecule part 2 | These 2 parts of different molecules get attracted to each other leading to H bond.The attraction between the opposite poles of different h2o molecules leads to cohesiveness.

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
