You add a neutron to the nucleus of the atom. How many protons, neutrons, and electrons do you have now

14. complete and balance the equations for the single displacement reactions. a. zn + pb(no3)2 -> b. al + niso4 -> 15. complete and balance the equations for the double displacement reactions. a. agno3(aq) + nacl(aq) -> b. mg(no3)2(aq) + koh(aq) -> 16. complete and balance the equations for the combustion reactions. a. __ ch4 + o2 -> b. __ c3h6 + o2 -> c. + o2 ->

In which of these cases are the two wave points considered to be in phase with each other?

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