Ionic solutes are considered strong electrolytes. What does this mean for the conductivity of the solution?
A) Strong electrolytes dissolve and completely dissociate in water providing charged ions to conduct electricity.
B) Strong electrolytes dissolve and do not dissociate in water providing no charged ions to conduct electricity.
C) Being a strong electrolyte refers the type of bonding and has no bearing on conducting electricity.
D) Strong electrolytes do not dissolve in water and can not conduct electricity.
ANSWER:
A) Strong electrolytes dissolve and completely dissociate in water providing charged ions to conduct electricity.
Answer:
Explanation:
Let the speed of light in vacuum is c and the speed of light in medium is v. Let the angle of incidence is i.
By using the definition of refractive index
refractive index of the medium is given by
n = speed of light in vacuum / speed of light in medium
n = c / v ..... (1)
Use Snell's law
n = Sin i / Sin r
Where, r be the angle of refraction
From equation (1)
c / v = Sin i / Sin r
Sin r = v Sin i / c
Assuming that there is in a vacuum, the two object will cool at the same rate, because the objects are made of the same material they will have the same cooling rate, assuming the surrounding temperature is the same.
