it tells us that three atoms of oxygen are contributing to the formation of this compound alongwith calcium and carbon...
The formula CaCO3 represents 5 atoms: 1 calcium atom, 1 carbon atom, and 3 oxygen atoms.
There is 1 Carbon atom in the formula along with 1 calcium and 3 oxygen atoms
Chemical formula for marble is CaCO3. Ca means calcium. C means carbon. O means oxygen. here it means 1 calcium, 1 carbon and 3 oxygen. They also call marble as calcium carbonate.
The answer is 'subscript'
NaHCO(subscript)3
The subscript is mentioned only in a chemical formula.3 FeCl3 in a chemical reaction is not similar to Fe3O4 in a chemical formula.
It is CaCO3.....it is the same as marbleFormula: CaCO3
FeCl3 (the 3 is a subscript)
The number 3 in the chemical formula CaCO3 indicates that there are three oxygen atoms in one molecule of calcium carbonate.
The formula CaCO3 represents 5 atoms: 1 calcium atom, 1 carbon atom, and 3 oxygen atoms.
There is 1 Carbon atom in the formula along with 1 calcium and 3 oxygen atoms
Chemical formula for marble is CaCO3. Ca means calcium. C means carbon. O means oxygen. here it means 1 calcium, 1 carbon and 3 oxygen. They also call marble as calcium carbonate.
The answer is 'subscript'
NaHCO(subscript)3
The chemical formula of iron(III) nitrate is Fe(NO3)3. Subscripts are "3".
As would be more apparent from its properly written formula, Zn(ClO3)2, each formula unit contains 6 oxygen atoms, the product of the subscript immediately following the oxygen atomic symbol and the subscript following the parenthetical formula of the chlorate polyatomic ion of which the oxygen atoms present are a part.
There are 5 atoms represented in the formula CaCO3: 1 calcium (Ca) atom, 1 carbon (C) atom, and 3 oxygen (O) atoms.
