A single bond represents this many electrons
2
Double arrows in a chemical reaction indicate a
reversible reaction
bitterness and high OH- concentrations are characteristic of
bases
These are the units used for molarity
moles per liter
All of the planet's ecosystems are included in this
biosphere
This type of chemical bond is found in organic compounds.
covalent bonds
In a chemical reaction at equilibrium, the rates of the forward and reverse reactions are
equal
A substance with a pOH of 9 will have a pH of
5
A solution is comprised (made up of) these two substances
solute & solvent
A reaction which releases heat into the environment
exothermic reaction
This is the main element found in most organic compound
Carbon
lowering activation energy
A pH of 8 is 1000 times _________________ than a pH of 5.
more basic
1.5 M NH3 (ammonia) is read as
1.5 molar NH3 (ammonia) solution
This type of activity has recently released CO2 from deep within the Earth
anthropogenic activities
Carbon can form these three types of bonds
single, double, and triple covalent bonds
This states that a system at equilibrium will return to an equilibrium state if it experiences a change in temperature, pressure, or concentration.
Le Châtelier's Principle
This is the classification of a substance that will yield H+ ions in a solution
Arrhenius acid
This property determines the maximum amount of solute that can fully be dissolved in a solution
Solubility
Every substance has this unique property which causes an increase in its temperature
specific heat
The subatomic particles involved in the bonds of organic compounds.
valence electrons
This is the minimum amount of energy particles require for a chemical reaction to take place
activation energy
A substance with an H+ ion concentration of 5.01 x10-8 has a pH of
7.3
This type of solution has too much solute.
The difference in the sum of enthalpies of reactants and products is known as
delta H
