All organisms need X to surviveLife began in X and is necessary for many chemical reactions to sustain life. X is also the only common substance to exist in the environment in all three states of matter.
Hydrogen bonding in water molecules is the result ofHydrogen bonds are an electrical attraction between water molecules. Hydrogen bonding leads to cohesion, adhesion, surface tension, and high specific heat in water.
The amount of heat a liquid must absorb for 1 g of it to be converted from liquid to gas is XWater has a high X which helps moderate Earth's climate.
What keeps organisms from overheatingThis also has to do with water's high heat of vaporization
Ice is more X than liquid waterThis means that bodies of water do not freeze solid so that life may continue underneath a frozen layer of water.
Water is the solvent of X
If a substance is X it has an affinity for waterA substance that is X doesn't necessarily need to dissolve completely in water. Colloids are X substances that do not dissolve in water because the molecules are too large.
Substances that repel water are XThese are nonionic and nonpolar (water isn't attracted to nonionc/nonpolar substances because water is polar)
An acid X the hydrogen concentration of a solution.Bases do the opposite.
X acids reversibly release and accept hydrogen ionsStrong acids and strong bases will disassociate completely.
A neutral solution has a pH of XAcids will have a pH less than X while bases have a pH greater than X. pH = -log[H+]
A X minimizes the pH change within a solutionX are found in the blood to make sure that the blood's pH is maintained. A X works by taking hydrogen ions from a solution when there are too many and releasing them when there are not enough.
Acid precipitation has a pH less than 5.6 and results from X in the atomosphereAcid precipitation can damage life in water and wash away mineral ions like calcium and magnesium that buffer the soil solution and make other toxic minerals more soluble.
