100 POINTS (picture included)
Based on Figure 2, which statement best describes what
happens to the amount of matter in the reaction?
There are 54 atoms in the reactants and 54 atoms in
the products.
There are 15 reactant molecules that become the 15
product atoms.
The 15 reactant molecules are destroyed to produce
energy in the form of flames.
The fuel molecule is broken in half and each half makes
molecules of water and carbon dioxide as products.
