The subscript is written to the lower right of the element symbol. For example, in H2O , the number 2 is the subscript for hydrogen and means that there are 2 atoms of hydrogen in the compound of water; since there is no subscript for oxygen it is assumed to be one atom of oxygen.
Similarly, what is the significance of the formula h2o? H2O is the chemical formula of water. It means that each molecule of water is made up of two hydrogen atoms, indicated by the letter H, and a single oxygen atom, represented by the letter O. Water is chemical substance with no smell, taste or color. H20 is dihydrogen monoxide or simply water. The 2 is the subscript of H, which represents the presence of 2 Hydrogen atoms.
In this case, hydrogen is bonded to oxygen. How do you type a subscript? Pressing the respective shortcut again will get you back to normal text. H2o is used to give you energy its sort of like water in fact it is water which is why you have drinks called h2o and stuff like that. Log in.

To explain her absence, the producers decided to let Rikki and Cleo mention that Emma is traveling the world with her family. The number 2 indicates that there are two atoms of hydrogen in a molecule of water. There is also one atom of oxygen but the number one is omitted from a chemical formula.
Answer: Water is in fact a chemical. H20 is dihydrogen monoxide or simply water. The 2 is the subscript of H, which represents the presence of 2 Hydrogen atoms. In this case, hydrogen is bonded to oxygen. Representing Compounds Consider the compound water as an example. Each water molecule contains two hydrogen atoms and one oxygen atom. The O for oxygen has no subscript.
When there is just one atom of an element in a molecule, no subscript is used in the chemical formula. Why is oxygen written as O2?
The difference between oxygen O and oxygen O2 is that the former is an oxygen atom while the latter consists of two O atoms bound together, forming a molecule also called oxygen.
Oxygen is usually found as a diatomic gas. Therefore, we write it as O2. We breathe in oxygen and some of this carbon dioxide. Types of VBA Errors 3. Runtime errors — When the code is usually correct in principle, but an action taken by the user or the data being used leads to unexpected errors. Visual Basic can generate custom errors of any data type, including Exception objects, by using the Throw statement.
An application can identify the error by displaying the error number and message of a caught exception. The code can trap and examine run-time errors. On Error GoTo 0 disables error handling in the current procedure.
