Chemical Reactions
Properties of water
Acids and Bases
100
Carbon Hydrogen Oxygen Nitrogen Sulfur Phosphorus
What are the basic atoms of life
100
Strong, = sharing of e-, equal electronegativities
What is Non-polar covalent
100
Reactant+Reactant(energy)=Product & water
What is a synthesis reaction, aka dehydration synthesis, aka anabolism
100
This property of water makes it an excellent solvent
What is it's polar covalent bonds
100
This substance dissociates into one or more hydrogen ions (H+) and one or more anions (-)
What is acid
200
Protons and Neutrons
What is the composition of the nucleus of an atom
200
Strong, un= sharing of e-, unequal electronegativities
What is a polar covalent bond
200
Product + water -> reactant, reactant & energy
What is a decomposition reaction/hydrolysis reaction/catabolism
200
When water is attracted to other water molecules
What is cohesion
200
This molecule binds with H+ when dissolved in water. Some dissociate into cations (+) and hydroxyl ions (OH-)
What is a base
300
Number of protons in a nuclei
What is the atomic number
300
weak, no sharing of e-, opposites attracted, cations, anions, form salts
What is an ionic bond
300
Requires energy to form a bond. Ex photosynthesis
What is a endothermic reaction
300
When water is attracted to other polar molecules
What is adhesion
300
This is an acid loving microbe
What is an acidophile
400
Sum of the masses of the protons, neutrons and electrons; also approximated by the sum of the number of protons and neutrons
What is the atomic mass
400
weakest, no e- sharing, weak attraction due to particle charge, important in stabilizing shape of 3D molecules
What is hydrogen bonds
400
Releases energy. Ex cellular respiration
What is an exothermic reaction
400
It has a neutral pH
What is the reason water can act as an acid or a base
400
This is a microbe that prefers a high pH
What is an alkalinophile
500
The same element with a different amount of neutrons
What is an ion
500
Cannot be destroyed or created, only rearranged.
What are atoms
500
Sum of all chemical reactions in an organism Catabolisn & Anabolism=
What is metabolism
500
Critical in carrying out chemical reactions in all organsims
What is hydrolysis and dehydration synthesis reactions
500
A neutral pH level is preferred by this microbe
What is bacteria
