The Continental Congress. 1  In the First Continental Congress, Patrick Henry, a delegate from Virginia, made the bold statement that I am not a Virginian, I am an American. 2  At the time of the congress, there were around 2.5 million people living in the United States.
Next Question. The main ingredient in eggshells is calcium carbonate (the same brittle white stuff that chalk, limestone, cave stalactites, sea shells, coral, and pearls are made of). The shell itself is about 95% CaCO 3 (which is also the main ingredient in sea shells).
A pearl is a hard object produced within the soft tissue (specifically the mantle) of a living shelled mollusk. Just like the shell of a clam, a pearl is composed of calcium carbonate in minute crystalline form, which has been deposited in concentric layers. The ideal pearl is perfectly round and smooth, but many other shapes (baroque pearls) occur.
