CHEMICAL EQUATIONS

WHAT ARE CHEMICAL EQUATIONS? A CHEMICAL EQUATION IS USED TO SHOW THE CHANGES THAT TAKE PLACE DURING A CHEMICAL REACTION. REACTANT + REACTANT = PRODUCT

WHY ARE THEY IMPORTANT? CHEMICAL EQUATIONS ARE IMPORTANT WHY IDENTIFYING THE REACTANTS AND PRODUCTS IN A CHEMICAL REACTION. CHEMICAL EQUATIONS ARE ALSO NEEDED TO BALANCE EQUATIONS; WHICH IS ANOTHER IMPORTANT PART OF CREATING AND ASSESSING CHEMICAL REACTIONS.

IMPORTANT TERMS USED IN CHEMICAL EQUATIONS: CHEMICAL REACTION – THE CHEMICAL CHANGES THAT OCCUR REACTANTS – THE SUBSTANCES THAT IN REACT IN THE CHEMICAL CHANGE PRODUCTS – THE SUBSTANCES FORMED AT THE END OF THE REACTION

THE DIFFERENT TYPES OF CHEMICAL EQUATIONS: CHEMICAL EQUATIONS CAN BE WRITTEN IN ONE OF TWO WAYS… WORD EQUATION: DESCRIBING THE REACTION USING THE FULL NAME SKELETAL EQUATION: DESCRIBING THE REACTION USING THE SYMBOLS

HOW DO I WRITE AN EQUATION? 1) IDENTIFY THE REACTANTS AND PRODUCTS 2) PLACE THE REACTANTS AND PRODUCTS ON THEIR CORRECT SIDES (REACTANTS GO ON THE LEFT AND PRODUCTS GO ON THE RIGHT) ** DEPENDING ON WHETHER OR NOT YOU ARE WRITING A SKELETAL OR WORD EQUATION YOU MAY NEED TO BALANCE IT
