Question:

lime wire....?

ok, i just downloaded limewire, but, i want to keep my computer protected from viruses, but nortin anivirus wont work, what do i do????

Answer:

Liming could be good or bad, depending on how it is used. Sloppy liming could kill off your acid-loving ornamentals: rhododendrons, pine trees, etc. It could kill off a a bog habitat.
What is limewater? Limewater can be made by dissolving either calcium oxide (CaO) or calcium hydroxide (Ca(OH)2) in water.6 When CaO is used, it first hydrates to Ca(OH)2 on contact with water (H2O):( you can obtain calcium oxide by heating limestone. that is calcium carbonate) CaCO3 ------.> CaO + CO2 (1) CaO + H2O à Ca(OH)2 + heat Consequently, there is little difference between using CaO and Ca(OH)2 except that CaO gives off a substantial amount of heat when it hydrates. When these materials dissolve, they dissociate in the water to calcium ions (Ca++) and hydroxide ions (OH-): (2) Ca(OH)2 à Ca++ + 2OH- For those more chemically inclined it is interesting to note that limewater actually contains a substantial amount of partially dissociated, but fully dissolved calcium monohydroxide: When carbon dioxide is dissolved in water, it hydrates to form carbonic acid: (4) CO2 + H2O ---> H2CO3 the carbonic acid equilibrates to form mostly carbonate: (5) H2CO3 + 2OH- ----> 2H2O + CO3-- It is the carbonate that we are concerned with here. It can combine with the calcium in solution to form insoluble calcium carbonate: (6) Ca++ + CO3-- ===> CaCO3 (solid) The result of this reaction is visually obvious. The calcium carbonate can be seen as a solid crust on the surface of limewater that has been exposed to the air for a day or two. It also settles to the bottom of the container. Since solid calcium carbonate is not an especially useful supplement of calcium or alkalinity,8 this reaction has the effect of reducing the potency of the limewater.
