same number of each element
Molecules that have identical molecular formulas but the atoms in each molecule are arranged differently are called isomers.
If the equation has the same number of each type of atom on both sides of the arrow, it is balanced. If the number of atoms on each side of the arrow is not the same, the equation is not balanced. For example, in the equation H2 + O2 -->H2O, there are two hydrogen atoms and two oxygen atoms on the left, and two hydrogen atoms and one oxygen atom on the right. Therefore, the equation is not balanced. However, in the equation 2H2 + O2 -->2H2O, there are four hydrogen atoms and two oxygen atoms on the left and four hydrogen atoms and two oxygen atoms on the right, so the equation is balanced.
the actual number of atoms in a molecule
Yes, an element can be represented as a chemical formula. Each element is identified by a unique chemical symbol, such as "H" for hydrogen or "O" for oxygen. Chemical formulas are used to represent the composition of compounds, which are combinations of elements.
All chemical formulas are called chemical notations. They represent the elements and the number of atoms of each element present in a compound.
formulas
its usually indicated by a subscript! :D
a molecule or compound. Each element is represented by its chemical symbol (e.g. H for hydrogen), and the number of atoms of each element is denoted by a subscript following the symbol (e.g. H2O for water).
The chemical formula of a compound provides information about the elements present in the compound and the ratio in which they are combined. The subscripts in the chemical formula indicate the relative number of atoms of each element in a compound.
To balance a chemical equation, you need to ensure that the number of atoms of each element is the same on both sides of the equation. This is done by adjusting the coefficients in front of the chemical formulas.
The word for a statement that uses chemical formulas to describe a chemical reaction is a "chemical equation." This equation represents the reactants and products involved in the reaction, showing their respective chemical formulas and the conservation of mass. Chemical equations can be balanced to ensure that the number of atoms of each element is the same on both sides of the equation.
Yes, superscript numbers in chemical formulas represent the number of atoms of each element present in a molecule or unit of a compound. These numbers are called subscripts and indicate the ratio of each element in the compound's formula.
Chemical formulas are made of symbols representing elements and subscripts indicating the number of atoms of each element in a molecule.
Coefficients can be adjusted in front of the chemical formulas to balance chemical equations. Changing coefficients will ensure that the number of atoms of each element is equal on both sides of the equation. Subscripts within chemical formulas should not be changed to balance equations.
A chemical equation is balanced when the number of atoms of each element is the same on both sides of the equation. To determine if a chemical equation is balanced, count the number of each type of atom on both the reactant and product sides and adjust the coefficients in front of the chemical formulas to make the number of atoms equal on both sides.
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 .
