Superscripts tend to be reserved for exponents, charge symbols and very little else. Subscripts commonly show what type of data is on display. For example if you have variable "t" in your equation (=time) then subscript "0" would mean when t=0...in other words, at the start of the experiment. Rate constant (K) is also prone to having subscripts attached, again they tell you about what this K relates to. Seeing "obs" as subscript tells you this is an observed rate constant, one that has been gained via experimental procedure rather than theoretical calculation.

What does subscript indicate in a chemical formula?
The number of atoms of the same element in the molecule
In a chemical formula what is used to indicate the number of atoms of each element?
It is called a subscript. For example: In the formula for water (H2O), 2 is the subscript indicating that there are 2 hydrogen atoms in the compound .
What does the subscript 2 indicate int he compuonds mgcl2?
In chemical compounds, subscripts indicate how many of that element are present in the compound, compared to the rest of the compound.In MgCl2, the subscript indicates that there are two chlorine atoms for every atom of magnesium.
Do you have to use subscript in chemical formulas?
Not every chemical formula requires subscript. For example table salt is NaCl, sodium chloride. No subscript. But most chemical formulae do require subscript, such as water, H2O.
The elements that make up a compound and the exact number of atoms of each element in a unit of the compound can be?
Subscript (:This is a subscript: (Na2) the "2" is the Subscript.
What are the symbols and numbers called that indicate the atoms in a compound?
Subscript
What does the subscript 2 indicate in the formula?
there are two atoms in the molecule
What does the subscript indicate in the chemical formula?
The number of atoms of that element in the molecule
What does the subscript 2 indicate in the formula O2?
there are two atoms in the molecule
What does a subscript indicate in a formula?
The number of atoms of the same element in the molecule
What does subscript indicate in chemical formulas?
The number of atoms of the same element in the molecule
How do you indicate the number of molecules in a substance?
The subscript outside the parentheses: (H2SO4)2
What does subscript indicate in a chemical formula?
The number of atoms of the same element in the molecule
Why does the oxygen symbol O not have a subscript?
Because symbols for the elements do not have subscripts. A subscript is added in the chemical formula of a compound to indicate how many atoms of the element are included in a molecule of the compound. For example, when hydrogen (H) and oxygen (O) combine to form water (H2O), a subscript 2 is added to the H to indicate there are two hydrogen atoms in a molecule of water, but no subscript is added to the O, because there is only one oxygen atom is in a molecule of water.
what number represents the subscript in the formula shown?
The letter or letters that represent an element are called its atomic symbol. The numbers appearing as subscripts in the chemical formula indicate the number of atoms of the element immediately before the subscript. If no subscript appears, one atom of that element is present.
Is the subscript a small number written above a letter or number?
A subscript is a small number written below the number, whilst a superscript is written above the number. A superscript 2 is used to indicate a squared number.
What small letter subscripts do we use to indicate whether a substance is a solid?
The indication for a solid is (s) as in BaSO4(s); the subscript is not usual.
