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.
The subscript to the right of an element tells you how many atoms of that particular element are in a molecule. For example, in the water molecule H2O, there are two hydrogen atoms and one oxygen atom.
You multiply the coefficients times the subscripts for each element in order to determine the number of atoms of each element on both sides of the equation. The absence of a coefficient is understood to be 1, and the absence of a subscript is understood to be 1. For example, in the balanced equation 2H2 + O2 --> 2H2O, there are 4 atoms of H (coefficient of 2 x subscript of 2) and 2 atoms of O (coefficient of 1 x subscript of 2) on the left side, and 4 atoms of H (coefficient of 2 x subscript of 2) and 2 atoms of O (coefficient of 2 x subscript of 1) on the right side, therefore the equation is balanced.
Subscripted numbers in a chemical formula represent the ratio numbers of atoms of all different elements which are present in that compound.
Subscripts show the number of atoms in a molecule.
What information can you determine from the coefficients in this balanced chemical equation? Mg + 2HCl → MgCl2 + H2
false
No! You can change coefficients as needed to balance an equation but you cannot just change a substance's subscripts.
False. Subscript cannot be change to balance chemical equations. Only coefficients can be added to balance chemical equation.
A coefficient is the number that goes before an element when your balancing the equation. And a subscript is the number after the element. Subscripts are not changed when you balance the equation.
Balancing only allows you to change the coefficients, NOT the subscripts.
Tsubscripts of the reactants equal the subscripts of the products.

Subscripts state how many atoms and Coefficients state how many molecules there are. So when balancing an equation you always adjust the coefficients. When this equation is balanced, what is the coefficient for Ni(NOËÄ)ËÄ? 4
A balanced chemical equation has correct placed coefficients and a representative chemical equation need these coefficients.

Both. you must have the correct subscripts to represent the correct chemical then you only change the coefficients to balance the equation. The product of a coefficient and a subscript tells how many atoms are present.
These subscripts are down the chemical symbol and at right. Example: O2
A coefficient is the number that goes before an element when your balancing the equation. And a subscript is the number after the element. Subscripts are not changed when you balance the equation.
