What is the frequency of the green light emitted by a hydrogen atom with a wavelength of 525 nm?

1 answer:

8 0

The frequency of the green light emitted by a hydrogen atom with a wavelength of 525 nm is $5.71$ × $10^{14} s^{-1}$

What is wavelength?

It is the length between two successive crests or troughs of any wave.

What is a frequency?

It is the total number of waves that pass through a fixed point in unit time.

Wavelength=525nm

The relation between wavelength and frequency

$v=\frac{c}{lambda}$

$v=$ frequency

$c=$ speed of light = $3.0$ × $10^{8}$ $m/sec$

λ(lambda)=wavelength

substitute the value in the equation mentioned above

$v=3.0$ × $10^{8}$ $/525$ × $10^{-9}$

$=5.71$ × $10^{14}$ $s^{-1}$

hence, the frequency of the green light emitted by a hydrogen atom with a wavelength of 525 nm is $5.71$ × $10^{14} s^{-1}$

9. Calculate the specific heat capacity of titanium if a 43.56 g sample absorbs 0.476 kJ as its temperature changes from 20.5 oC

Shalnov [3]

Answer:

c = 0.528 J/g.°C

Explanation:

Given data:

Mass of titanium = 43.56 g

Heat absorbed = 0.476 KJ = 476 j

Initial temperature = 20.5°C

Final temperature = 41.2°C

Specific heat capacity = ?

Solution:

Specific heat capacity:

It is the amount of heat required to raise the temperature of one gram of substance by one degree.

Formula:

Q = m.c. ΔT

Q = amount of heat absorbed or released

m = mass of given substance

c = specific heat capacity of substance

ΔT = change in temperature

ΔT = 41.2°C - 20.5°C

ΔT = 20.7 °C

476 J = 43.56 g × c × 20.7 °C

476 J = 901.692 g.°C × c

c = 476 J / 901.692 g.°C

c = 0.528 J/g.°C

Cyclohexane (C6H12) is a hydrocarbon (a substance containing only carbon and hydrogen) liquid. Which of the following will most

SVETLANKA909090 [29]

Answer: $CH_{3}CH_{2}CH_{2}CH_{2}CH_{3}$

Explanation: Hydrocarbons are the compounds which contain only carbon and hydrogen as their constituent elements. These are considered to be as the non polar species as because of the less electronegativity difference between the two components.

Now as it is a non polar species thus it will dissolve only a non polar solute following the principle of 'Like dissolves Like'. Thus the most non polar species given in the options is pentane. Cyclohexane will definitely dissolve this pentane as both are non polar in nature.

$CH_{2}Cl_{2}$ , HI and NaBr are polar specie which cannot be dissolved in non polar species.
