No. Shellfish are mostly devoid of calcium. The primary sources of calcium are dairy products.
biological precipitation
Yes.
no
Yes it is.
yes :)
Even the Sand Is Made of Seashells was created in 2006.
Because seashells are made of Calcium Carbonate, which when reacted with acid produces carbon dioxide and water.
Calcium Carbonate - CaCO3 This is found in rocks such as limestone and is the main component of seashells Calcium Chloride - CaCl2 This is a salt which is found naturally in very small quantities Calcium Hydroxide - Ca(OH)2 My understanding is that this does not occur naturally, it is very useful in many industries Calcium Oxide - CaO Created during the decomposition of limestone To name a few.
Producer
no because they are not magnetic and their not made of magnet
You put the seashells in a cup of vinegar
That is the correct spelling of the element "calcium" (notably in bones and seashells).
you dont hahahahahahahahahaha
Seashells are not made out of only carbon. They are a mixture of compounds. Calcium carbonate is a main compound in them.
they are made mainly from calcium and from a few other minerals.
No they are not exactly the same Both contain calcium and taces of different element but are not totally having the same composition
Mostly calcium carbonate (limestone -chalk).
The seashell is fomed from calcium carbonate; CaCO3 is thermally decomposed by heating.
Seashells are hard because they are mainly made of calcium, a hard mineral, which is what bones are made of.
yes, seashells are ionic because all the components of seashells like calcium carbonate, calcite and conchiolin are ionic compounds. by kingsley Ifang (BSc Ed. chemistry) university of uyo, Nigeria.
Accretion means gradually growing by layers. Seashells grow by accretion as the animals add new layers of calcium.
No, the calcium the earth has is all it will have. It is not renewable. Most of the calcium available is in fossil form (e.g. ancient coral reefs, deposits of seashells, organic ooze) that will take millions of years to be replaced (like coal, petroleum, and natural gas). However it is easy to use calcium from bones and seashells harvested today.
