WebJun 15, 2008 · Answer. 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.

WebSep 6, 2016 · However, if you wanted them to react differently, you might try to take advantage of the different non-acid parts ($\ce{SO4^2-}$ and $\ce{Cl-}$). So for sulfuric acid and hydrochloric acid, $\ce{SrSO4}$ will form, but $\ce{SrCl2}$ will stay in solution. Therefore, sulfuric acid will react with strontium ion, while hydrochloric acid will not. WebHornfels, with its alternating bands of dark and light crystals, is a good example of how minerals rearrange themselves during metamorphism. Hornfels is shown in table 1. ...

Undiluted acids are very dangerous. Concentrated HCl or Concentrated H2SO4 will react VERY vigorously with the metal. The reaction with concentrated acids is highly exothermic (releasing heat). The H2 gas that is produced as a result of the reaction might get ignited by the heat, and burn violently. cyber monday knives

Web3) What major change occurs during metamorphism of limestone to marble? A) calcite grains grow larger and increase in size. B) limestone grains react to form quartz and feldspars. C) clays crystallize to micas, forming a highly foliated, mica-rich rock. D) calcite grains are dissolved away leaving only marble crystals. WebAnd, about base-base reaction: neutralization occurs by the acid donating electron (s) and the base receiving it. But in base-base reactions, that can't happen because both the bases need electron (s) but there's no free electron (s) in the solution. Hence, no reaction. What physically happens, I don't know.
