What is pure sample of calcium?
A pure sample of calcium is a silver-white metal that is highly reactive and not typically found in its elemental form in nature. It is commonly found in compound form, such as calcium carbonate in rocks like limestone, or in calcium phosphate in bones and teeth.
Is calcium a pure substance?
Yes. Calcium is an element, and it has the atomic number 20 and Ca is its chemical symbol. It is a metal, and one of the alkali earth metals which are the elements in Group 2 of the periodic table. It is reactive, and as such is not found free in nature, but always appears in compounds with other elements. Wikipedia has additional information, and a link is provided.
What kind of pure substance is calcium or carbon?
Calcium is an example of a pure substance known as an element, specifically a metal. Carbon is also a pure substance, but it is an element that belongs to the non-metal group.
Is eggshell a mixture or a pure substance?

What is calcium carbonate an example of?
Calcium carbonate is an example of a chemical compound that is used in a variety of applications, including as a dietary supplement, antacid, and in the manufacturing of cement, paper, and plastics.
What happens when calciun carbonate reacts with a neutral?
A reaction takes place I think. Neutral substance is a substance with a pH of 7 like pure water and when water reacts with calcium carbonate, calcium hydroxide and carbon 4 oxide is formed.
