If electron jumps from n =1 to n = 2 in hydrogen atom then how will we find recoil velocity of atom ( I am just beginner and had never crossed such question so can't understand where to start)
I'm working on chemistry and I'm not quite sure how to solve this question? I haven't worked with moles before and whenever I try to figure out how to do these types of question I only end up confusing myself more.
How many Mg atoms are in 5.7892 mol of Mg(NO3)2?
How many N atoms does t...
