What does the subscript 2 show in this chemical equation H2O 2H plus O?
The subscript 2 in H2O indicates that there are 2 hydrogen atoms in each water molecule. This is important for balancing chemical equations and understanding the composition of compounds.
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 is the chemical expression of dihydrogen oxide?
The chemical formula of dihydrogen oxide is H2O. This means that the subscript for hydrogen in this chemical expression is 2.
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 does the subscript 2 show in this chemical equation H2O 2H plus O?
The subscript 2 in H2O indicates that there are 2 hydrogen atoms in each water molecule. This is important for balancing chemical equations and understanding the composition of compounds.
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.
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 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 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 is the chemical expression of dihydrogen oxide?
The chemical formula of dihydrogen oxide is H2O. This means that the subscript for hydrogen in this chemical expression is 2.

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

What is the small number called to the right of the symbol molecule and the chemical equation?
It's called a subscript, and in the formula for a substance, it tells you how many representative particles you have of that substance. If there is no subscript, it is understood to be 1, which means you only have 1 representative particle of that substance. Examples: H2O, or water, means you have 2 hydrogen atoms and 1 oxygen atom. Ca(NO3)2, or calcium nitrate, means you have 1 calcium atom, and 2 nitrate polyatomics (comprised of a total of 2 nitrogens and 6 oxygens.) A subscript outside a set of parentheses distributes to everything in the parentheses.
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 of oxygen dichloride?
The chemical formula of dichlorine monoxide is Cl2O - 2 is a subscript.
