Study Notes
Chemical Equations
- The purpose of balancing a chemical equation is to ensure that the same number of atoms of each element is present on both the reactant and product sides.
- A chemical equation that has the same number of atoms of each element on both the reactant and product sides is called a balanced equation.
- The arrow (→) in a chemical equation indicates the direction of the reaction, separating the reactants from the products.
- A formula equation uses chemical formulas instead of words to represent the reactants and products.
- The term for the process of writing a chemical equation using chemical formulas and balancing it is equation writing or equation balancing.
Chemical Equations
- The purpose of balancing a chemical equation is to ensure that the number of atoms of each element is the same on both the reactant and product sides.
Balanced Chemical Equation
- A chemical equation that has the same number of atoms of each element on both the reactant and product sides is called a balanced chemical equation.
Arrow in Chemical Equations
- The arrow (→) in a chemical equation indicates the direction of the reaction, from reactants to products.
Formula Equations
- A formula equation is a chemical equation that uses chemical formulas instead of words.
Writing Chemical Equations
- The term for the process of writing a chemical equation using chemical formulas and balancing it is called equation writing or equation balancing.
Purpose of Chemical Equations
- The purpose of writing a chemical equation is to represent a chemical reaction in a concise and symbolic way.
Balanced Chemical Equation Result
- A balanced chemical equation ensures that the Law of Conservation of Mass is upheld, meaning that matter is neither created nor destroyed in a chemical reaction.
Characteristics of Balanced Chemical Equations
- A characteristic of a balanced chemical equation is that the number of atoms of each element is the same on both the reactant and product sides.
- The correct direction of the arrow in a chemical equation is from reactants to products, indicated by →.
- One characteristic of a balanced chemical equation is that it does not have a fractional coefficient.
- The purpose of coefficients in a balanced chemical equation is to balance the number of atoms of each element on both sides of the equation.
