Balance the skeletal equation and decide what type of reaction it is: N2 + F2 --> NF3
1. N2 + F2 --> NF3, synthesis
II. N2 + 3F2 --> NF3, synthesis
III. N2 + 3F2--> 2NF3, decomposition
IV. N2 + 3F2--> 2NF3, synthesis

Put these processes of the water cycle in the correct order, starting at the point where the water is in the lake: 1. water evaporates into the atmosphere 2. rain, snow, or other precipitation falls 3. water collects into larger bodies of water 4. water vapor condenses into liquid water
