100
These are the three basic structures in which carbon based molecules are found
What are chains, branched/forked chains, and rings
100
Chemical reactions that absorb more energy than they release
What is endothermic reactions
100
This element has the highest melting point of all elements
What is carbon (3500 degrees Celsius)
200
This is the term for elements that are found in your body, and are considered essential, but at very small quanitities
What is a trace element
200
The attraction between a hydrogen atom on one substance to a negatively charged particle on another substnace
What is a hydrogen bond
200
These are the four main types of carbon based molecules found in living things
What are carbohydrates, fats/lipids, proteins, nucleic acids
200
The bond energies in the products of these reactions are lower than those of the reactants
What is exothermic reactions.
200
the most abundant organic molecule on earth, with over 100 billion tons of it being produced on earth every year
What is cellulose
300
The part of the atom that has the greatest mass
What is the nucleus
300
A material composed of two or more elements or compounds that are physically mixed together but not chemically combined.
What is a mixture
300
these are the polymer forms of carbohydrates, lipids, and proteins (three separate terms...)
What are polysaccharides, triglycerides, and polypeptides
300
Energy that is needed to get a reaction started
What is activation energy
300
This is the simplest explanation of why fructose and glucose are different even though their molecular formulas are both C6H12O6
What is their structures are different
400
This is a pure substance that consists entirely of one type of atom
What is an element
400
This property of water contributes to thermal regulation in everything from our bodies to the globe as a whole
What is high specific heat
400
These are the monomer forms of carbohydrates, lipids, proteins, and nucleic acids (4 terms)
What are monosaccharides, fatty acids, amino acids and nucleotides
400
Proteins that act as biological catalysts
What are enzymes
400
The graph of the change of energy throughout the process of an exothermic reaction (draw...)
What is a good drawing? the bond energy of the product should be lower than that of the reactants, the energy level should increase during activation energy...
500
This is any member of a large class of gaseous, liquid, or solid chemical compounds whose molecules contain carbon.
What is an organic molecule
500
cohesion is responsible for this force, which is necessary to stretch or break the surface of a liquid
What is surface tension
500
These are the functions of carbohydrates, lipids and proteins respectively (3 separate functions)
What is providing energy
storing energy
and life functions (including forming enzymes, transport, forming stuctures, fight diseases.....etc)
500
This is when energy is released
What is when bonds are formed
500
ALL ARE ELIGIBLE TO GET POINTS FOR THIS:
- An accurate illustration of a bond between Na and Cl before an after the bond is formed.
- Accurately represent electron clouds of each before and after bonds (are they positive or negative?)
-Identify when they are ions.
What is: The before bond should show 1 electron in Na's valence shell and 7 in chlorine. The after should show that Na is now + in net energy, while Cl is -. And the after is when they are ions
