2 parts hydrogen and 2 pArts oxygen
Subscripted numbers are listed after each element to indicate the number of atoms of that element in the compound. For instance the formula for water is H2O, which indicated that there are 2 hydrogen atoms and 1 oxygen atom (no subscript implies the number 1).
which is not true about the chemical formula of a sbstance? a.it gives the number and kinds of atoms present. b.it shows that a substance has a definite compound. c.it shows the elements present in the compound. d.it shows the phase of a substance.
There are 20 atoms and there are 6 Carbon atoms, 8 Hydrogen atoms, 6 Oxygen atoms.
No. Everything has mass. Atoms have mass, Everything has atoms. :) Atomic Mass Number for example. :)
A chemical formula is the number of atoms in a substance, and is the same as a molecular formula (provided the substance is a molecule - if not, it has no molecular formula). A structural formula shows how the atoms are linked, and there are different interpretations of this: eg C3H8O2 is the chemical formula of 1,2 propan di-ol, which is the same as the chemical formula of 1,1 propan di-ol the structural formula however is CH2OHCHOHCH3 for 1,2 propan di-ol and CH(OH)2CH2CH3 for 1,1 propan di-ol. A displayed formula shows all the bonds: ........H..OH...H.............O-H...H...H ........|....|.....|..................|....|.....| ....H-C.-.C.-.C.-.H.....H-O-C.-.C.-.C.-.H ........|....|.....|..................|....|.....| ....H-O...H....H.................H...H....H 1,2 propan di-ol........1,1 propan di-ol ---------------------------------- Some chemicals, such as table salt, have no molecule. Thus, they only have chemical formula but not molecular formula. The chemical formula of table salt is NaCl. There are other salts, such as Na2SO4, MgSO4, etc. (If you hear people saying "the salt molecule has the formula of NaCl...", believe me, they do not know what they are talking about.) Some compounds exist as molecules- discrete entities, such as water. This kind of compounds have molecular formula. Water's is H2O. Structural formula? Never heard of.
A molecular formula shows the numbers and kinds of atoms in a molecule but not the arrangement of the atoms.
A chemical formula gives the number ratio of the different kinds of atoms present in the compound. This means that the ratios are the same if you count in individual atoms, dozens of atoms, or molecules of atoms.
the number and kinds of atoms in the compoundIn an ionic compound, the formula gives the ions and their ratios in the crystal lattice. In a molecular compound, the formula gives the numbers of atoms of each element in a molecule.

The chemical formula of a compound shows the number of atoms of each element in the smallest unit of the compound. The smallest unit is a molecule for covalently bonded compounds and the minimum number of each of the right kinds of atoms to achieve electro-neutrality for ionically bonded compounds.

Acetic acid has the formula of CH3COOH. It consists of carbon, hydrogen and oxygen as its constituent molecules.

Your question is not so clear. Methane has carbon and hydrogen atoms, the chemical formula being CH4. Dodecane contain also carbon and hydrogen atoms, the chemical formula being C12H26; the number of carbon and hydrogen atoms is here different. Or, otherwise it is clear that 10 g of methane contain more atoms than 1 g of methane.
No, the chemical formula shows both the kinds of atom in a molecule and the number of each type of atom. For example, the formula H2O shows that there are 2 hydrogen atoms and one oxygen atom in a water molecule.
