1. the cause of fish kill is The most common cause is reduced oxygen in the water, which in turn may be due to factors such as drought, algae bloom, overpopulation, or a sustained increase in water temperature. Infectious diseases and parasites can also lead to fish kill. Toxicity is a real but far less common cause of fish kill.
2. Transfer the extra living species on a wide container(if it's too much) and must make another pond so that the living things in the container will properly managed.
Activity 3
1.) The "rust" is actually iron oxide and forms when the iron in the nail reacts with the oxygen in the air or in liquids. The molecules of iron on the surface of the nail exchange atoms with the oxygen in the air and produce a new substance, the reddish-brown ferrous oxide
2.) we need the nails are covered with a zinc alloy. The zinc provides a protective coating that helps prevent the nail from rusting.
3.)Moisture: The corrosion of iron is limited to the availability of water in the environment. Exposure to rains is the most common reason for rusting.
Acid: if the pH of the environment surrounding the metal is low, the rusting process is quickened. The rusting of iron speeds up when it is exposed to acid rains. Higher pH inhibits the corrosion of iron.
Answers & Comments
•What could be the cause of the fish kill?
The fishpond was overpopulated.
•What is needed in the overpopulated fish pond?
It needs to lessen the fish on the pond and the others should be in a tank/container/aquarium.
•What causes the formation of rust in the iron nails?
It was decomposed by the oxygen and water
•What shall we do with the iron nails to minimize or prevent it from rusting?
Paint it, Keep it dry, Coat it and use stainless steel
•What are the two factors that influence the formation of rust in the iron nails?
Water and oxygen are the 2 factors that influence the rust in iron nails.
