Chlorine gas (Cl2) and sodium (Na) make sodium chloride (NaCl) which we also know as table salt.
2Na + Cl2 = 2NaCl
I think it is B. Sorry if I’m wrong
Repeat the experiment to make sure it gives the same results.
Hope i helped ; )

Answer:
a)1.51*10^-22joules b) 1.89*10^-7m
Explanation:
Work done to stop the proton = the kinetic energy of the proton = 1/2 mv^2 = 1/2* 1.67*10^-27* 425*425 = 1.51* 10 ^ -22 joules
b) net force acting to stop the proton = 8.01*10^-16
Work done needed to stop the proton = net force acting opposite the motion * distance
Distance covered = need work done/ net force
Distance = 1.51*10^-22/8.01*10^-16= 1.89*10^-7m
