Balancing Chemical Equations

Question 1

3 parts of a chemical equation

Answer 1

reactants, yield (chemical reaction), and products

Question 2

how do u know if an equation is balanced or not

Answer 2

make sure the same amount of each element is on both sides

Question 3

how does balancing equations relate to the law of conservation of mass

Answer 3

because you dont create or destroy particles, just transfer them and keep the same amount on both sides
