Water is Wet
Vocab: Made up of two or more different atoms
Compound
Vocab: Made up of only one type of atom
Element
Drawing: Draw two water molecules attracted to each other
Mickey mouses ears to chin
Vocab: Attraction between water molecules and the glass of a capillary tube
Adhesion
Fill in the Blank: Water is called the universal solvent because it is a _______ molecule, which allows it to dissolve most polar and ionic solutes.
Polar
Vocab: Smallest unit of measurement having unique chemical properties
Atom
Vocab: Anything that has mass and takes up space
Matter
Drawing: Draw a hydrogen bond - label the charges on the hydrogen and oxygen
Surface tension
Fill in the Blank: If a substance does not dissolve in water, we can conclude that the covalent bonds in the substance are ______ and the electrons are shared equally.
Vocab: Bond formed when electrons are shared between 2 atoms
Covalent Bond
Vocab: Equal sharing of electrons (does not have a charge)
Nonpolar
Drawing: Draw a hydrogen bond - label the covalent bond
Where the ears meet the head on a single molecule
Vocab: Allows water molecules to move upward through a narrow tube such as the stem of a plant
Capillary Action
Fill in the Blank: Oil will not dissolve in water, so a mixture of oil and water is called a ______.
Suspension
Vocab: Bond formed when electrons are lost or gained
Ionic Bond
Vocab: Unequal sharing of electrons (has a charge)
Polar
Drawing: Draw a hydrogen bond - label where the hydrogen bond actually is
Where the ears of one molecule meet the head of the other molecule
Vocab: Why does water not change temperature quickly
High Specific Heat
Fill in the Blank: When you dissolve sugar in iced tea, the sugar would be a ______.
Solute
Vocab: Weak attraction between polar molecules
Hydrogen Bond
Vocab: Contains the protons and the neutrons
Nucleus
Cohesion
Fill in the Blank: Ice floats because it has a lower _____ than water.
Density
Chitty Chat: Tell me how either cohesion, adhesion, high specific heat, solubility, or density are related to the polarity of water.
Cohesion - water molecules are polar so they stick to each other
Adhesion - Water molecules stick to other polar molecules around them
High Specific Heat - hydrogen bonds make it hard for the temp of water to fluctuate
Solubility - water can dissolve other polar molecules
Density - when water freezes the hydrogen bonds stop moving, allowing more air between the bonds
