Transcript of Copy of Writing and Balancing Chemical Equations

Writing and Balancing Chemical Equations A chemical equation describes the ingredients used during a chemical reaction and the amount of products formed. It is, if you like, similar to a recipe. There are several parts that make up a chemical equation
Reactants or ingredients are the elements or compounds that are being changed during the reaction and appear on the left of the equation. Products are the new elements or compounds being formed during the reaction and appear on the right of the equation.
Reactants are always used up during a chemical reaction while the products increase in quantity The Law of Conservation of mass tells us that the amount of each element on the reactant side, must be present in the same amount on the product side of the equation. Steps for Balancing an Equation

1. Get yourself an unbalanced equation



2. Draw boxes around all the chemical compounds, molecules, or elements. To balance chemical equations, a coefficient must be placed in front of the element or compound that is not balanced.
Once the coefficient is added, all elements present in the compound are increased by the value of the coefficient. Scientists use a special way of writing to describe what happens in a chemical reaction. They describe a chemical reaction by writing a chemical equation using symbols to represent the atoms taking part. Reactants Product 3. Make an element inventory.
In this inventory, your job is to figure out how many atoms of each element you have on the left and right sides of the equation. Coefficient: Indicates the amount of reactants or products
COEFFICIENTS ARE USED TO BALANCE EQUATIONS

Subscript: Tells you how many atoms of each element are in the equation
NEVER CHANGE A SUBSCRIPT TO BALANCE AN EQUATION Coefficient Subscript Yields Reactants Yields
