I know I am successful when I can:
 Identify and describe these biochemical reactions:
___________________, _________________________.

Chemical reactions involve ____________ and ____________ of chemical
_____________ leading to changes in the composition of _____________.
Example:
2 H2 (g) +
O2 (g)
2 H2O (l)
Chemical Equilibrium

Some chemical reactions go to completion (all ________________ are converted to
_____________)

Most reactions are _________________meaning that products of the forward reaction
become the ______________ of the reverse reaction
Example:
C6H12O6 +
6 O2
6 CO2 + 6 H2O (respiration)
6 CO2 + 6 H2O
C6H12O6 +
6 O2 (photosynthesis)
OR
3H2 + N2
2NH3
Equilibrium is reached when ammonia __________________ as quickly as it is formed
