Hint :Dihydrogen monoxide, most commonly known as water, is a transparent fluid forming the world's streams, oceans, lakes and rain, and is actually the major component of the fluid of organisms. A molecule of water is a chemical compound containing one oxygen atom and two hydrogen atoms which are connected through covalent bonds.
Complete Step By Step Answer:
As the name suggests, the given compound dihydrogen monoxide comprises a non-metal hydrogen and another non-metal oxygen. We know that any compound containing a non-metal and another non-metal is considered to be a covalent compound (most commonly known as molecular compound). Now let us identify the formula for the given molecular compound i.e. dihydrogen monoxide. Rules for writing the formula of a molecular compound are listed below:
1) Write the symbol for each of the elements according to their appearance in the periodic table.
In the present case, the symbol for hydrogen is and the symbol for oxygen is in accordance with the periodic table.
2) Add a subscript to each of the elements according to its prefix. The examples of the subscript corresponding to its prefix are listed below:
In the present case, for the given compound ‘dihydrogen monoxide’ hydrogen has prefix di- which indicates the subscript 2 and oxide i.e. oxygen has prefix mono- which indicates subscript 1 to be used.
Hence combining the rule 1 and 2, the formula for dihydrogen monoxide is .
Note :
While writing the chemical formula of molecular compound or any other compound like ionic compound, never write the subscript '1'. Writing the formula of a molecular compound is considered to be the simplest. While in case of ionic compounds (containing metal and non-metal), we have to take into account the charges of each of the elements present in the compound.
