What does a subscript show in a chemical formula?
The subscript in a chemical formula represents the amount of that atom in that compound's formula.
What is the subscript of oxygen dichloride?
The chemical formula of dichlorine monoxide is Cl2O - 2 is a subscript.
How do you determine the number of atoms in a chemical equation with subscripts and coefficients?
To determine the correct subscripts in a chemical formula, take H2O as an example. H has a charged of positive 1 while O has a charge of negative 2. To balance out the charges of the two elements, 2 H cations are needed to balance out O negative 2 cation. This will result to H2O.
What does the small number 2 show in chemical equation?
Don't know what "this" chemical reaction is, but chances are, the small 2 is a subscript. Subscripts are used in chemistry to represent how many atoms you have in a compound. For example, in the formula MgCl2, that 2 tells you that you have 2 chlorines for every 1 magnesium. If there is no subscript (like after the magnesium), that means there's only 1 atom. Kind of like in algebra, when you see the variable "x" it really means 1-times-x; you just don't show the 1. In chemistry, the subscript only refers to whatever element is immediately before it. If the subscript is outside a set of parentheses, it refers to everything within the parentheses.
What is the chemical formula for the oxygen we breathe?
The chemical formula for the oxygen in the air is O2, where the 2 should be a subscript.
What are two things you cannot do to a subscript in a chemical equation?
1. You cannot change the subscript just to help you balance the equation. You can only balance an equation by using whole-number coefficients written at the beginning of a substance. 2. If no subscript is present, you can't just add one to help you balance the equation for same reason listed above.
What does a subscript show in a chemical formula?
The subscript in a chemical formula represents the amount of that atom in that compound's formula.
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 do subscripts in chemical equations tell about the equation?
The subscript in the equation tells you how many atoms of that element there are in the reaction. For example: H20 --> H2 + O2 Before the reaction there are 2 hydrogen atoms and 1 oxygen (the subscript 1 isn't shown). After the reaction there are 2 hydrogen atoms and 2 oxygen atoms. Keep in mind that this is a skeleton equation and isn't balanced yet.
What is the subscript of oxygen dichloride?
The chemical formula of dichlorine monoxide is Cl2O - 2 is a subscript.
What is the balanced chemical equation for sodium and hydrochloric acid reacting to produce sodium chloride and hydrogen?
Do not try this! 2Na +2HCl --> 2NaCl + H2 The last 2 should be a subscript.

What is the subscript for ammonium in the chemical formula ammonium dichromate?
Ammonium Dichromate: (NH4)2Cr2O7. The subscript on Ammonium (NH4) is 2.

The chemical formula for the oxygen in the air is O2, where the 2 should be a subscript.
What is a subscript and where is it located in a chemical formula?
In a chemical formula, a subscript is a number written to the right and slightly below the symbol for the chemical element. If the subscript is 1, it is not written. The subscripts for the chemical formula for water, H2O, are 2 for hydrogen and 1 for oxygen. The subscripts for the chemical formula for glucose, C6H12O6, are 6 for carbon, 12 for hydrogen, and 6 for oxygen.
In the chemical formula for magnesium chloride what is the number 2 called and what does it tell you?
subscript
