Equations for chemical reactions may require one or more whole-number coefficients in order for the equation to balance. Balancing a chemical equation upholds the law of conservation of mass, which states that matter cannot be created or destroyed. The coefficients represent molar ratios of reactants and products. Performing stoichiometric calculations is largely dependent upon these correct molar proportions.
What else can I help you with?
What do the subscript and coefficent in a chemical equation tell us?
The subscript in a chemical equation tells us the ratio of atoms of each element present in a compound. The coefficient tells us the number of molecules or formula units involved in the reaction.
Which number in a chemical equation shows you the number of atoms?
The coefficient times the subscripts in a chemical formula show you the number of atoms of each element for each substance in the equation.
Which is represented in a chemical equation?
A chemical equation represents a chemical reaction in which reactants are converted into products. It shows the chemical formulas of the substances involved in the reaction and the proportions in which they combine.
The chemical equation that shows all ionic reactants and products is known as?
The chemical equation that shows all ionic reactants and products is known as an ionic equation. In this type of equation, only the species that are involved in the reaction are shown as ions, while spectator ions are omitted.
An expression in which symbols and formulae represent a chemical reaction?
A chemical equation is an expression in which symbols and formulae represent a chemical reaction. It shows the reactants on the left side and the products on the right side, with coefficients to balance the number of atoms on each side.
A number in front of a chemical formula in a chemical equation is called a?
coefficent
What are the two meanings of coefficent in chemical equation?
Number of moles or number of particles.
A number that is lower and smaller than the letter symbols in a chemical formula that shows how how atoms of a substance are in a molecule is called?
coefficent
A number that is lower and smaller than the letter symbols in a chemical formula that shows how many atoms of a substance are in a molecule is called?

What is coefficent in math?
The number in the front of the equation. Example 2x-3k..so the 2 nd the 3 are the coefficent.
What do the subscript and coefficent in a chemical equation tell us?
The subscript in a chemical equation tells us the ratio of atoms of each element present in a compound. The coefficient tells us the number of molecules or formula units involved in the reaction.

What info does a chemical equation provide?
A chemical equation shows a reaction between to chemicals using chemical formulas.
When does a chemical equation is balanced when it shows?
a balanced equation shows the correct proportion and mole/grams of the reactants involved....
What is a chemical equation that shows the same number of each kind of atom on both sides of a chemical equation called?
Balanced
Which number in a chemical equation shows you the number of atoms?
The coefficient times the subscripts in a chemical formula show you the number of atoms of each element for each substance in the equation.
What is a coefficient in science?
a coefficent in physical science means:a number in front of a chemical formula in an equation that indicates how many molecules or atoms of each reactant and product that are involved in a reaction
