I have no idea what im suppose to do here, I understand chemistry but they didn't write anything down for this.

BUBBLE TOP LEFT AND TO TOP RIGHT
next to left bubble is N2+3h2 and there is an arrow to the right pointing to 2NH3 which means that n2+3h2 is 2NH3
Below both is another bubble, but I have no idea what to put in the left right or bottom bubble

Based on the information provided, it seems like you have a chemical reaction in the form of:

N2 + 3H2 → 2NH3

The left bubble might represent the reactants, so you can write N2 and 3H2 in it.

The right bubble may represent the products, so you can write 2NH3 in it.

As for the bottom bubble, it is unclear what it represents based on the information given. If you have more context or additional information, please provide it for further assistance.
the bottom bubble has another arrow pointing down
If there is another arrow pointing down from the bottom bubble, it might indicate a separation or another process happening after the formation of the product NH3. Without further information, it is difficult to determine what should be written in the bottom bubble or understand the complete context. If you can provide more details or the specific question, I would be happy to help you further.
