The one labelled "molecule A".
False
Since there is no product, and only 1 reactant, it is not an equation, and thus, 4 molecules of sodium chloride
This is the equation which indicates the appearance of diffraction pattern caused by a molecule in path of the electron beam. 1 Molecular representation of electron diffraction pattern is extended using wierl equation
When acetone react with phenylhidrazine equation is phenylhidrazone of acetone, condensation product in which process water molecule eliminate.
The molecule phosphatidylcholine lecithin - C40H80NO8P
The amount of each molecule
The subscript denotes how much of that atom is in the molecule.
The chemical symbol (not equation) of hydrogen is H; the diatomic molecule is H2.
If a molecule has ends with opposite charges, it is usually referred to as a dipole, or polar.
Covalent molecule.
DNA

CO2 is carbon dioxide. You may have got this from a balanced equation. The 6, called a coefficient, in front of the molecule shows how many of the molecule is needed for it to balance out with the rest of the equation.
The change in the DNA sequence is referred to as a mutation
The double helix.
DNA
