The reactants are the substances on the left side, which react and give the products on the right side.
The reactants are Fe and O.
The product is Fe2O3.
The arrow to the right means that the reaction is going in only one direction — the only reaction happening at the moment is that Fe and O are making Fe2O3.
(s) means the substance is in the solid state, and (g) means in a gaseous state (or the substance is a gas in that reaction).
C. Theres decreased Biodiversity Most likely because of natural or human causes (deforistation)
Answer:
B if they run out of fuel then they would probably keep going because there is nothing that would stop them other than like a planet or something.
Explanation:
The presence of a large population of sludgeworms indicates water depleted of oxygen and a high level of organic pollution.
The sludgeworms Tubifex is harvested and sold as tropical fish food since it is common near sewer outlets and serves as a sign of water or organic pollution. Polychaetes are crucial in rearranging the silt on the ocean floor.
Organic contamination happens when too much organic material, such sewage or manure, gets into the water.
There will be more decomposers and sludgeworms in a pond as the organic content accumulates. These decomposers and sludgeworms develop quickly and consume a lot of oxygen as they do so.
Hence, Sludgeworms are a sign of an abundance of oxygen-depleted water and significant levels of organic pollutants.

Water is a polar molecule. Because of this, it has both adhesion and cohesion. This means it sticks to other matter. Adhesion is when water sticks to different matter and cohesion means it sticks to identical molecules of itself. Water has hydrogen bonds that are attracted to the oxygen atoms in other molecules of H2O.
