There are two atoms of hydrogen on the left and four on the right. This makes the reaction unbalanced.

What’s Pavlovian?

Ivan Pavlov used to train dogs to react a certain way to stimuli by using either rewards or punishments. It works on humans too: we associate the sound of a slow-moving vehicle with a certain type of bell with ice cream, so when we hear that bell we race over to get our ice cream. Even if there's not actually an ice cream truck ringing the bell. It's known as a Pavlovian response.
