An atom that has 84 protons and 86 neutrons undergoes a reaction. At the end of the reaction, it has 82 protons and 84 neutrons.

Answer: The atom undergoes alpha decay.
Explanation: An atom has 84 protons and 86 neutrons initially. When this atom undergoes a reaction the product obtained has 82 protons and 84 neutrons.
As the product obtained has 2 protons less and 2 neutrons less which means that the mass number is decreased by 4 units and atomic number is reduced by 2 units.
The atom undergoes an alpha-decay because in this decay the particle emitted is alpha particle which has an atomic number of 2 and atomic mass of 4 units.
Equation follows:
The atom which is undergoing alpha decay is Polonium (Po) and the product formed is Lead (Pb).

Here in order to find out the distance between two planes after 3 hours can be calculated by the concept of relative velocity
here
speed of first plane is 700 mi/h at 31.3 degree
speed of second plane is 570 mi/h at 134 degree
now the relative velocity is given as
now the distance between them is given as
so the magnitude of the distance is given as
miles
so the distance between them is 2985.6 miles
