본문내용

Chemical reactions often accompanies visual signals
Bubbles form
ex) the hydrolysis of water
A flame is produced
ex) when natural gas reacts with oxygen, blue flame can be observed



SECTION 6.1 / 6.2
Balancing Chemical Equation
Principle : chemical reaction do not create or destroy any atoms during the reaction
The number of atoms for each element should be equal for the both side, reactants and products
Balancing chemical equation : making sure that the number of atoms for each element corresponds to the each other (reactants, products)
