CaCO3--Calcium carbonate--calcium, carbon, oxygen.
Calcium carbonate (CaCO3) easily react with acids.
The eggshells of quail, or any other bird, are mainly calcium carbonate (usually about 95%). The remainder is mostly calcium phosphate, magnesium carbonate, and various proteins.
sea shells have an ionic bond. since theyre mostly calcium carbonate
Gravel made mostly of calcium carbonate, often in the form of limestone.
Mostly Calcium carbonate(CaCO3)
Limescale is mostly calcium carbonate with some magnesium carbonate mixed in there as well. So the answer would be calcium.
Limestones are mostly made up of Calcite or Calcium Carbonate (CaCO3). Calcium Carbonate is basic in nature.
CaCO3--Calcium carbonate--calcium, carbon, oxygen.
Limestone is mostly calcium carbonate.
Mostly calcium carbonate. 93% of it.
Yes it is although there are other things that make marble up swell as calcium carbonate but it is mostly that !
mostly calcium carbonate and sausages
Mostly calcium carbonate (limestone -chalk).
Limestone is mostly calcium carbonate. processing the total carbonates in the limestone via titration will work, using an acid such as hydrochloric acid.
Calcium carbonate (CaCO3) easily react with acids.
Technetium is not a naturally-occurring element; it was created in a laboratory.
