Hey there! A mixture is material composed of two or many elements that are mixed together but are not chemically combined.

Hope this helped you.

Answer:

energy = 391.902 kJ /mol

Explanation:

given data

wavelength = 305 nm = 305 × $10^{-9}$ m

to find out

average energy

solution

we know speed of light is 3 × $10^{8}$ m/s

so we find frequency here first by speed of light formyla

speed = wavelength × frequency

3 × $10^{8}$ = 305 × $10^{-9}$ × frequency

frequency = 9.8360 × $10^{14}$ $s^{-1}$

so energy is

energy = hf

here h = 6.62 × $10^{-34}$ J-s

energy = 6.62 × $10^{-34}$ × 9.8360 × $10^{14}$

energy = 6.51 × $10^{-14}$ J

energy = 6.51 × $10^{-14}$ × $\frac{6.02*10^23}{1000}$ kJ/mol

energy = 391.902 kJ /mol

At critical temperature, the resistivity of the superconductor

B. It suddenly drops to zero

Explanation:

Materials can be classified into three different types depending on their resistance:

Conductors: these materials have generally low resistance and allow electricity to pass through easily. The resistance of a conductor increases linearly with the temperature
Insulators: these materials do not allow electricity to pass through - so they have very high resistance
Semi-conductors: these are materials that are insulators are room temperature, however they becomes conductors when heated. Therefore, the resistance of a semiconductor decreases when the temperature increases
Superconductors: these are special materials that are normally conductors; however, at very low temperatures (we are talking about temperature very near to 0 K), their resistance becomes suddenly zero.

Therefore, the correct answer is:

B. It suddenly drops to zero
