NAME 3 PARTS TO CHEMICAL REACTIONS
|
REACTANTS
YIELDS OR PRODUCE AND END PRODUCTS EX: C + 0 *(2) -------> CO(*2) |
|
|
COMBUSTION
|
BURNS IN THE AIR
|
|
|

|
|
WHEN AN ELEMENT GAINS ELECTRONS IT HAS BEEN ________
|
REDUCED

|
|
WHEN ELECTRONS ARE LOST THEY SHOW UP WHERE
|
ON THE RIGHT SIDE OF THE EQUATION

|
|
WHAT DOES THE LAW OF CONSERVATION MEAN
|
ALL THE ATOMS PRESENT AT THE START OF THE REACTION (LEFT SIDE OF THE EQUATION) MUST STILL BE PRESENT AT THE END
