it's a subscript
subscript
The number placed in front of an element's symbol in a chemical formula indicates the quantity of atoms of that element present in a molecule. This number is known as a coefficient. For example, in the formula (2H_2O), the coefficient "2" signifies that there are two molecules of water, each containing two hydrogen atoms and one oxygen atom. If no number is present, it is understood to be one (1).
Balancing a chemical equation can often require a whole-number coefficient placed in front of a chemical formula. This upholds the Law of Conservation of Matter, which says that matter cannot be created or destroyed. These coefficients must be in the lowest possible ratio.
more electropositive element first, followed by electronegative elements
In a chemica formula coefficients indicate the number of atoms in a given molecule. Example: K2CO3 The molecule contain two atoms of potassium so the coefficient is 2 and three atoms of oxygen so the coefficient is 3.
The number placed in front of a chemical symbol or formula is called a coefficient. It represents the number of molecules or formula units in a chemical reaction.
A coefficient is placed in front of a chemical formula to indicate the number of molecules or atoms involved in the reaction. It affects the entire chemical formula that follows it in the equation.
In a chemical Equation ,The reactants are on the left side of a chemical equation and the products are on the right side.The number in front of a chemical formula in a chemical equation is called atoms. They should be a balancing number on both the sides.
The number placed in front of a chemical formula in a chemical equation is called a coefficient. Coefficients are used to balance chemical equations by ensuring that the number of atoms of each element is the same on both sides of the equation.
In a chemical equation, a coefficient is a number placed in front of a chemical formula to balance the equation by ensuring that the number of atoms for each element is equal on both sides. It represents the ratio of moles or molecules involved in the reaction.
subscript
The number placed below an element's symbol in a chemical formula is called a subscript. Subscripts indicate the number of atoms of that element in a molecule.
Coefficient. It generally corresponds to the number of moles of the molecule / atom under consideration.
Yes.
The number placed below an element symbol in a chemical formula is called a subscript because it indicates the number of atoms of that element in a molecule or compound. The subscript is written slightly below the element symbol to differentiate it from the coefficient, which applies to the whole molecule or compound.
