Stealing signs is not always against the rules. Major League baseball's prohibition pertains to stealing signs via electronic means only. Attempts by a team to steal signs during the game simply by observing or by other allowable means are permitted, but obviously risky and unpopular.
The metamorphic rock we selected was marble, which is formed from limestone and contains dolomite and calcite as the two main sediments. Great question! Unfortunately, I can't give an easy answer to this one. Before we continue, let's agree on some basics: calcium is an element, calcite and dolomite are minerals, and limestone is a sedimentary rock which can turn into the metamorphic rock called marble if the right conditions occur.
Commodity: Limestone, a sedimentary rock that is dominantly composed of the calcium-bearing carbonate minerals calcite and dolomite. Calcite is chemically calcium carbonate (formula CaCO3). Dolomite is chemically calcium-magnesium carbonate (formula CaMg(CO3)2). It is used as a soil conditioner to neutralize acidity and to add calcium and magnesium nutrients. 2  Quicklime is calcium oxide (formula CaO) that is produced by calcining (burning) high-calcium limestone in a lime kiln to drive out the carbon in the form of carbon dioxide gas (formula CO2).
