Question | Answer |
Water is a polar molecule because _____________________. | it has one end that is negatively charged and another end that is positively charged |
In a water molecule, the hydrogen atom has a slight __________ charge. | positive |
Polar mixes (likes) __________ molecules. | polar |
In our lab, oil and water did not mix because oil is __________. | nonpolar |
In our lab, water and food coloring mix because food coloring is __________. | polar |
A ______________ bond is formed when atoms share electrons. | covalent |
Two types of bonds occur because opposite charges attract, they are: | ionic and hydrogen |
In a single water molecule, the hydrogen and oxygen atoms are held together by a __________ bond. | covalent |
In a water molecule, the oxygen has a slight _______________ charge. | negative |
In an atom, protons and neutrons make up the _____________, of the atom and this has an overall ______________ charge. | nucleus, positive |
Water molecules are attracted to each other by ___________ bonds. | hydrogen |
Which property of water allows it to dissolve polar and ionic substances our bodies need such as salt. | universal solvent |
Which property of water allows water molecules to cling to other water molecules? | cohesion |
Water is pulled from the roots of a plant up its stem by ____________________. | capillary action |
Which property of water allows it to cling to another surface (such as the stem of a plant)? | adhesion |
Electrons have a __________ charge. | negative |
Be able to draw water molecules showing: hydrogen bonds, covalent bonds, correctly label the hydrogen and oxygen atoms and indicate their charges. | hydrogen (+ charge), oxygen (- charge); covalent bond between hydrogen and oxygen atoms; hydrogen bond between water molecules -- remember, opposites attract. |
Are hydrogen bonds a strong or weak bond? | weak |
Sodium chloride (table salt) is held together by an _______ bond. | ionic |
What property of water causes surface tension? | cohesion |
Why is it important for our cells that water is an universal solvent? | otherwise, substances like sugar and salt wouldn't be able to able to enter our cells |
How does salt dissolve in water? | As the ionic bond holding sodium chloride together breaks, the negative oxygen surround the positive sodium and the positive hydrogen surround the negative chloride. |
Is the cell membrane polar or nonpolar? | nonpolar |
