Explain the role played by dissolved oxygen in the general mechanism proposed to explain the various steps in crevice corrosion?
Dissolved Oxygen(usually between 20 - 60 ppm) reacts with H2O and the delocalized (conductive) electrons on the surface metal O2 + H2O + 4e- to form 4(OH)- ions that in turn draw the now charged (Fe2+) ions out into solution as 2Fe(OH)2...RUST
What is an ecm in a car?
ECM (engine control module) This is the brain of your vehicle. It takes in information from various sensors then sends out signals to items such as fuel injectors and timing to keep the engine running at its best for performance and fuel economy.
What is the meaning of 'Six degrees of separation'?
Due to the ability to make connections and friendships over greater distances (with easier travel, telephones, and later, the internet) it is hypothesized that everyone on the planet can be connected through no more than six "degrees of separation". For example, say I wanted to connect myself with the Queen of England. The first step would be for me to find a friend who was from England or had ties with people there. Then I would connect one of there friends to someone else until I had someone who knows the Queen. This should take no more than 6 of these "friend to friend" connections. ME-->Friend#1-->Friend#2-->Friend#3-->Friend#4-->Friend#5-->Queen So, although I don't know the Queen, or probably anyone after "Friend#1" I can be connected to her through acquaintances no more than 5 times removed.
