I just learned this in my chemistry class. The standard enthalpy of formation for ammonia gas, which is NH3, is -46.1 kJ/mol. That negative sign is very important. It means that heat is released when you make it. So the reaction gets warm. This is called an exothermic reaction. It is a number you see a lot in homework problems. I hope this answer is a help for you.

That song "UGH!" by the 1975 is a good one. It is about a big problem the singer has. His problem is with drugs. But not the hard drugs. He is talking about cocaine.

The word "Ugh" is the sound he makes. It is like a tired sound. He feels this way because he is always fighting this thing. He wants to stop using it. But it is very hard for him to quit. The song says it is a "recurring theme" in his life. That means it keeps coming back. He cannot escape it.

He sings that the drug makes him feel good for a short time. But then it makes him feel very bad after. He knows it is bad for him. He says it is a "gift" that you have to keep paying for. That means it takes your money and your health. It is not a real gift.

He also talks about how it affects his love life. He says a girl likes him more when he is using it. But he knows that is not a good reason. It is a fake feeling. He wants real love, not love because of a drug.

So the song is like a sad story. It is about his fight with addiction. He is telling us how it feels. He is not proud of it. He is just being honest. He wants to be better. But it is a very difficult fight. The music sounds happy and fun. But the words are very serious. That is the interesting part of the song. It makes you think about the problem.
