Life Insurance Mortality Tables. Life insurance companies use what is called a Life Insurance Mortality Table (aka actuarial table or life table) to come up with policy rates. This table takes your age and calculates how many years you have left to live if you live to the average life expectancy.
Rust is the normal electrochemical process of metals returning to their natural unrefined state. It occurs when Iron, Oxygen and Water (air moisture) combine. The rusting process can be accelerated when Iron is subjected to nature's minerals, chemicals and temperature fluctuations.
Other metals corrode. Rusting is an oxidation process. What we normally call rust is a flaky red-brown solid which is largely hydrated iron.The primary corrosion product of iron is Fe(OH)2 (or more likely FeO.nH 2 O), but the action of oxygen and water can yield other products having different colors:ther metals corrode.
