All elements have a unique atomic emission spectrum. in which of the following scenarios would this fact be most useful?

a. when trying to determine a star's chemical composition
b. when trying to determine how old an artifact is
c. when trying to measure the speed of sound

Lithium diisopropylamide [(ch3)2ch]2nli, referred to as lda, enjoys many uses as a strong base in synthetic organic chemistry. it is customarily prepared by the reaction of diisopropylamine [(ch3)2ch]2nh with butyllithium. draw the products of the reactions in the appropriate boxes and select the acid, base, conjugate acid, and conjugate base. be sure to answer all parts.

If the atomic mass of an atom is 34 and the atom contains 13 protons, how many neutrons does the atom contain?

If anyone would be able to me out with these three questions it would be these are from the chem 2202 course.
