Weekends, Babe went to the country grandmother. When her grandmother was cooking, the broken egg shells were thrown into the yard. Several hens in the hospital were competing for pecking. See this, Babe asked puzzled: “hen eat eggshell is good?” Grandmother said: “good thing, can calcium! ” [Questions raised] people eat eggshell can calcium? Access to information] Babe Internet access that: the main component of the egg shell is calcium carbonate (CaCO), content of 390%, people eat eggshell, calcium carbonate in the eggshell and stomach acid (the main component of hydrochloric acid) reaction: Ca CO3 + 2HCl = Ca Cl2 + CO2 ↑ + H2O, generating energy
