dialogue cause and effect
The dialogue about “cause and effect”
Dhea : Hi, how are you?
Inggi : Hello dhea, I'm fine. And you?
Dhea : I'm fine too. I have a question for you.
Inggi : Hello dhea, I'm fine. And you?
Dhea : I'm fine too. I have a question for you.
Inggi : What is that?
Dhea : If the nail is inserted into the water what effect will occur?
Inggi: Hmm, The nail inserted into the container containing the water are corroded due to the presence of O2 and H2O.
Inggi: Hmm, The nail inserted into the container containing the water are corroded due to the presence of O2 and H2O.
Dhea : okey inggi, thank you. Now I understand.
Inggi : you’re welcome de.
please tell me again about , If the nail is inserted into the water what effect will occur?
BalasHapusThe nail inserted into the container containing the water are corroded due to the presence of O2 and H2O.
HapusExplain how to reduce corrosion ?
BalasHapust can be done by:
HapusPainting: The paint forms a barrier between the metal and the environment, namely moisture.
Sacrificial anodes: Utilization of a metal lower on the Galvanic Series to be attacked first, instead of the metal in use. The sacrificial anode can be replaced as needed.
Passivation: Some corrosion processes will create solid metal compounds that will coat the initial site of corrosion and prevent further corrosion at that site.
Cathodic Protection: In the illustration below the iron is coated with a thin layer of zinc which is acting as a sacrificial layer for the iron. Instead of the the iron corroding, the Zn acts as the sacrificial anode in the cell and protects the iron.
What is the constituent element of water?
BalasHapusH + O2 >>> H2O
Hapuswhat it is corrosion?
BalasHapusCorrosion is a natural process, which converts a refined metal to a more chemically-stable form, such as its oxide, hydroxide, or sulfide
HapusIs it only oxygen and water that can cause corrosion? Explain in detail
