Determine the oxidation number for all of the atoms involved in the following reactions. Determine what is being oxidized and reduced. Determine what is the reducing agent and oxidizing agent. 1. MgI2 + Br2 ⇒ MgBr2 + I2
2. 5HClO + I2 +H2O ⇒ 5HCl + 2HIO3
3. 8H+ + Sn + 6Cl- + 4NO3- ⇒ SnCl62- + 4NO2 + 4H2O

Think about how you can use le chatelier’s principle to find possible solutions to the design problem. describe at least two ways to increase the yield (amount) of ammonia based on this principle.

Draw the skeletal structures of two different molecules that are each made of 5 carbon atoms and 12 hydrogen atoms.
