About three billion years ago, single-celled organisms called cyanobacteria lived in Earth’s oceans. They thrived on the ocean’s abundance of , which they used during the process of photosynthesis. Much later, this process allowed organisms, such as fish, to survive by extracting dissolved
from ocean waters.

The energy produced as a result of this flow of electrons from atom to atom is called

How does the entropy of steam compare to the entropy of ice?

The flame produced by the burner of a gas (propane) grill is a pale blue color when enough air mixes with the propane (c3h8) to burn it completely. for every gram of propane that flows through the burner, what volume of air is needed to burn it completely? assume that the temperature of the burner is 195.0°c, the pressure is 1.05 atm, and the mole fraction of o2 in air is 0.210.
