can be separated by using a magnet
Yes, fossils can be used to correlate widely separated sedimentary rocks by comparing their distinctive fossil content and applying the principle of fossil succession, which states that older fossils in the rock layers are found at the bottom, and younger fossils are found in upper layers. By identifying similar fossil assemblages in rocks in different locations, geologists can establish a relative timeline of deposition and correlate the rocks.
There are a few advantages to using limestone for building materials. Limestone is pretty and elegant looking. Limestone is also a strong material to work with. Limestone takes very little maintenance and is fairly inexpensive.
Yes, fossils can be used as index fossils. Index fossils are commonly used to date rock layers and correlate geologic formations based on the known age of the fossil. Fossils with widespread distribution and short geological range are typically chosen as index fossils.
When limestone (which is primarily composed of calcium carbonate) is put into vinegar (which is primarily acetic acid), a chemical reaction occurs. The acetic acid in vinegar reacts with the calcium carbonate in limestone to produce carbon dioxide gas, water, and calcium acetate. This reaction is often used in laboratory settings to simulate the process of chemical weathering on rocks.
I love fossils
Vinegar is made from Wine so perhaps using a white or red wine in place of vinegar?
One way is to use a process called sieving to separate the larger wood chips from the smaller particles of limestone, sawdust, and potassium nitrate. The sawdust and wood chips can be separated by flotation since sawdust floats while wood chips sink in water. Finally, the potassium nitrate can be dissolved in water and then filtered to separate it from the limestone.

Indiana has a limestone quarry. The outside of the house is limestone.
Cheese is made by curdling milk, either using rennet (an enzyme) or an acid like vinegar or lemon juice. The curds are then separated from the liquid whey, pressed, and aged to develop flavor. Different types of cheese are made using variations in this basic process.
Sugar and water can be separated by using a couple different methods. One method is by using an apparatus for distillation. Another is by using evaporation.
