It's a decent app, better than just a simple Q&A. I'm not a complete zero in chemistry, but I do run into problems sometimes)) For example, I ordered a solution on this site:
Condition: reduce a metal oxide weighing 7.09 g with an oxidation state of +2. The reducing agent is hydrogen in a volume of 2.24 L under normal conditions. Task: calculate the molar masses of the equivalents of the metal and the oxide, and the molar mass of the metal.
What I did:
1. I tried to solve it myself for an entire evening – zero results.
2. I downloaded the chemistry problem-solving app "Campus." Not by chance, but on a friend's recommendation, so I wasn't afraid to pay.
3. I took a photo of the problem and created a request.
4. I bought a subscription.
5. I got a response in 10 minutes.
6. They sent the solution in 30 minutes, and not just the steps, but with detailed explanations.
I want to emphasize again that they explain! They wrote where each number comes from, that this one is a constant value, etc. If chemistry is starting to make sense to you, but not right away, then download the app. They will help you solve a few problems, and then it will get easier.
