Fate of atoms in chemical reactions
Fate of atoms in chemical reactions
Neither created nor destroyed, only rearranged
Conservation of mass in reactions
Conservation of mass in reactions
Total mass remains constant throughout the reaction
Law of conservation of mass definition
Law of conservation of mass definition
Total mass of substances is conserved during reaction
Mass relationship: reactants vs products
Mass relationship: reactants vs products
Mass of reactants = Mass of products
Conservation: atoms vs molecules in reactions
Conservation: atoms vs molecules in reactions
Atoms are conserved; molecules are not conserved
Reason chemical equations must be balanced
Reason chemical equations must be balanced
Because atoms are conserved during reactions
Process of atoms during reactions
Process of atoms during reactions
Atoms rearrange to form new molecules/compounds
Number of each atom type before vs after reaction
Number of each atom type before vs after reaction
Remains the same (identical before and after)
System type where mass conservation applies
System type where mass conservation applies
Closed systems (gases can't escape)
Mass creation/destruction in chemical reactions
Mass creation/destruction in chemical reactions
Cannot be created or destroyed
