How would you solve this?

I've been trying to get help from friends, but none of them know how to solve it. I am learning Chemistry right now, and I've mastered how to write nuclear reactions and such. But, I don't know how to solve these problems. Could you provide the answers and the descriptions as to why they are correct? If you could reply to this fast, I would appreciate it. Thank you so much for your time !
