Is there a way to check reactions?
In August 2018 IBM launched a free cloud service called IBM RXN. This neural network is quite young, but it is constantly being trained, and the prediction should get better over time. I haven't used it all that extensively, but it seems it works quite adequately for simple reactions, including the OP's case. For example:



They also published a great paper [1] which describes on which base their AI operates.
