    What happens when acid reacts with limestone? | …

    Jun 15, 2008 Limestone is mostly made up of the mineral calcium carbonate (CaCO3). This is not very soluble, so rocks don't dissolve very quickly. But if you add an acid, you add hydrogen ions (H+), which will react with the carbonate to form hydrogen carbonate HCO3- ions, which are very soluble in water, and the limestone will dissolve. Or, if there is more acid, two hydrogen ions will

    Limestone has two origins: (1) biogenic precipitation from seawater, the primary agents being lime-secreting organisms and foraminifera; and (2) mechanical transport and deposition of preexisting limestones, forming clastic deposits. Travertine, tufa, caliche, chalk, sparite, and micrite are all varieties of limestone. Limestone has long fascinated earth scientists because of its rich fossil ...

  • Endergonic vs Exergonic Reactions and Processes

    Endergonic vs Exergonic Reactions and Processes

    Sep 16, 2019 Notes About the Reactions . You cannot tell how quickly a reaction will occur based on whether it is endergonic or exergonic. Catalysts may be needed to cause the reaction to proceed at an observable rate. For example, rust formation (oxidation of iron) is an exergonic and exothermic reaction, yet it proceeds so slowly it's difficult to notice the release of heat to the environment.

    Sedimentary Rock Examples and Types

    The three basic types of rocks are igneous, metamorphic and sedimentary. Sedimentary rocks make up most of the rocks on the earth and are formed when bits of rock, soil or organic matter settles and accumulates. Plant and animal fossils can be found in sedimentary rock.

  • How Concrete is Made

    How Concrete is Made

    How Concrete is Made. In its simplest form, concrete is a mixture of paste and aggregates, or rocks. The paste, composed of portland cement and water, coats the surface of the fine (small) and coarse (larger) aggregates. Through a chemical reaction called hydration, the paste hardens and gains strength to form the rock-like mass known as concrete.
