TEST: Chemical Reactions

This test will assess your current understanding of Systems and Scale. It will count toward your grade.

The 3 rules about atoms:

1. Atoms last forever.

2. Atoms make up the mass of all materials.

3. Atoms are bonded to other atoms in molecules.

The general format for chemical reactions: REACTANTS → PRODUCTS

Soda Water Fizzing Reaction      H₂CO₃ → CO₂ + H₂O  

Ethanol Burning Reaction           C₂H₅OH + 3O₂ → 2CO₂ + 3H₂O

Combustion Reactions, all          [fuel] + _O₂ → _CO₂ + _H₂O

You've got this!
