Match the definition: The branch of science which studies the chemical processes within living organisms.
Chemistry
Physics
Biochemistry
Anatomy
Match the definition: A substance formed by two or more elements combing (not necessarily a covalent bond) Ex. Water (H20 is made of Hydrogen and Oxygen)
Molecule
Ion
Compound
Covalent Bond
Match the definition: The basic unit of matter, the smallest unit of an element that retains the chemical and physical properties of that element. Made up of subatomic particles like protons, neutrons, and electrons.
Element
Ion
Molecule
Atom
Match the definition: A pure substance that consists entirely of on type of atom (Listed on the periodic table (Ex. Oxygen, Carbon)).
Ion
Isotope
Atom
Element
Match the definition: An electron in one of the outermost shell of an atom that can participate in forming chemical bonds with other atoms. (octet rule)
Ions
Ionic Bonds
Valence Electrons
Covalent Bonds
Match the definition: An atom that has a positive or negative charge due to loss or gain of electrons
Ion
Atoms
Molecule
Isotope
Match the definition: One form of an element, which contains the same number of protons but different numbers of neutrons (Ex. C12, C13, C14)
Valence Electrons
Molecules
Isotope
Hydrogen Bond
Match the definition: A chemical bond formed when one or more electrons are transferred from one atom to another. Atoms are held together by chemical attraction. (Ex. NaCI)
Covalent Bond
Ion
Element
Ionic Bond
Match the definition: Composed of two or more atoms held together by chemical bonds. (Ex. H20, C02, C6H12O6)
Ion
Molecule
Isotope
Element
Match the definition: Type of bond between atoms in which the electrons are shared (Ex. H2O) Strongest type of bond
Hydrogen Bond
Compound
Covalent Bond
Intermolecular Bond
Match the definition: The weak attraction between a hydrogen atom and another atom. Responsible for giving properties of water. Weakest type of bond.
Covalent Bond
Intramolecular Bond
Hydrogen Bond
Intermolecular Bond
Match the definition: Force between toms with one molecule. (Ex. Polar Covalent Bond holding the Oxygen and Hydrogen together in a water molecule)
Hydrogen Bond
Intramolecular Bond
Intermolecular Bond
Capillary Action
Match the definition: Force between different molecules (Ex. A Hydrogen Bond between two water molecules)
Intramolecular Bond
Intermolecular Bond
Hydrogen Bond
Buffer
Match the definition: The attraction between unlike (different) molecules (Ex. Water sticking to other substances like a leaf)
Cohesion
Bonding
Adhesion
Buffer
Match the definition: Compound that prevents sharp, sudden changes in pH
Capillary Action
Buffer
Ion
Compound
Match the definition: The tendency of water to rise in a thin tube due to adhesion and cohesion
Buffer
Hydrogen Bonding
Capillary Action
Cohesion
Match the definition: The attraction between molecules of the same substance (Ex. Water sticking to other water molecules)
Adhesion
Surface Tenstion
Cohesion
Transpiration
Match the definition: Reduction in temperature resulting from the evaporation of a liquid.
pH
Polarity
Solution
Evaporative Cooling
Match the definition: The measure of acidity or alkalinity (basicity) of an aqueous solution scaling from 1 (highly acidic) to 14 (highly alkaline) with a midpoint of 7 (neutral)
pH
Polarity
Specific Heat
Solvent
Match the definition: A molecule that has both a positively and negatively charged end. (Ex. H2O)
Properties
Surface Tenstion
Polarity / Polar
pH
Match the definition: Any measurable aspect or characteristic of an item.
Transpiration
Suspension
Polairty / Polar
Properties
Match the definition: The amount of heat energy required to increase the temperature of water by a certain amount (Ex. Amount of energy it takes to raise 1 mL of water 1 degree C)
Specific Heat
Surface Tenstion
Transpiration
Suspension
Match the definition: The intermolecular attraction at the surface of water which pulls the water molecules inward from the surface. Results in a higher tension between water molecules on the surface. (Ex. Pepper or leaves floating on the surface of water)
Specific Heat
Surface Tension
Solvent
Solute
Match the definition: Loss of water from a plant through its leaves
Cohesion
Transpiration
Versatile Solvent
Solution
Match the definition: Water's ability to dissolve more solutes than any other solvent due to polarity
