Answer:1.4
Explanation:
Angle of incidence= 38°
Angle of refraction=26.3°
From Snell's law: n= sin i/sinr
sin i= 0.6157
sin r= 0.4430
n= 0.6157/0.4430=1.4
Note, n is dimensionless
Because zinc is above lead on the activity series. This means that in a single displacement reaction such as this one, Pb will not easily displace Zn.
