With a pH of 12 it is very alkaline and would turn universal indicator dark blue.
Calcium Hydroxide is a base, therefore litmus paper would turn blue.
In this reaction calcium hydroxide is obtained, a basic product.
it goes green ph7 neutral

Limestone to quicklime: Calcium carbonate ---heat---> calcium oxide (QUICKLIME) + carbon dioxide Chemical formula: CaCO3 ---heat---> CaO + CO2 Quicklime to slaked lime: Calcium oxide (QUICKLIME) + water ---> calcium hydroxide (SLAKED LIME) Chemical formula: CaO + H20 ---> Ca(OH)2
Hydrogen gas. Ca + 2H2O ------> Ca(OH)2 + H2
Carbon dioxide is released.
If your water system is one that does water softening, than the sodium Hydroxide (also called caustic soda or lye) would be used to raise the PH before going into a softening tank. With a higher PH the mineral in the water will stick to something like sand that is added to the tank. The sand will get heaver and can be dropped out. Sodium hydroxide is also used in making soft drinks, chocolate and other foods.
Potassium Nitrate+Water HNO3 (aq)+KOH (aq)-->KNO3 (aq)+H2O (l)
HYdrogen. The Group (II) Alkaline Earth elements, of which calcium is one, react in a similar way the Group (I) Alkali metals, but less vigorously. So like sodium and water produces sodium hydroxide and hydrogen . # Then calcium and water produce calcium hydroxide and hydrogen. Here is the reaction eq'n. Ca(s) + 2H2O(l) = Ca(OH)2(aq) + H2(g) .
when sodium is dropped into water sodium hydroxide is produced leaving out hydrogen.
It will react slowly to form magnesium hydroxide and hydrogen gas.

Yes, it is correct.
Calcium metal is more dense than water. If you had a block of calcium and dropped it in a container of water, it would sink. Note! Calcium reacts with water! Calcium metal is stored in a container beneath kerosene or another liquid to isolate the metal from air. Calcium will chemically react with the moisture in air and will thus be decomposed.

Carbon dioxide is released.
Egg shells are rich in calcium. Birds need calcium to lay strong eggs. By giving the eggshells to birds you are producing less waste and contributing to the environment
In 10.6 the only way it will work is if the software company makes a "Universal" patch, Apple dropped the Classic program and Rosseta took it's place so you could still use a "Universal" patch. Your using 10.7 and are trying to open an older application with PPC/Universal code in it and Apple has dropped support for Classic/Roseta that was required to open it.
