Station #1

• 1) Write the thermochemical equation:

​

When solid nitrogen triiodide is exposed to light, it decomposes into nitrogen and iodine. It requires 88.7 kJ of energy for this reaction to occur.

Station #1

• Write the correct symbol for a chemical equation:
• Gas is released
• A ppt is formed
• The chemical is dissolved in water
• The reaction occurs in both directions simultaneously
• The reaction requires light or electricity to occur

Station #7

• 1) Classify as endothermic, exothermic, or both:
• A. The temp. Of the surroundings increases.
• B. The products have more energy than the reactants.
• C. The bonds of the reactants are broken.
