Answer:
Chlorine takes electrons from potassium in the reaction.
Explanation:
2K + Cl₂ ⟶ 2KCl
The KCl is an ionic solid.
It consists of K⁺ and Cl⁻ ions that are formed by the transfer of an electron from K to Cl.
The chlorine takes electrons from potassium, and Gain of Electrons is Reduction.
At the same time, potassium loses electrons to chlorine, and Loss of Electrons is Oxidation.
Both oxidation and reduction are occurring, so this is an oxidation-reduction reaction.
Gas is the most compressible at room temperature.
Answer:
6.56×10¹⁴ Hz
Explanation:
From the question given above, the following data were obtained:
Wavelength = 457 nm
Frequency =?
Next, we shall convert 457 nm to metre (m). This can be obtained as follow:
1 nm = 1×10¯⁹ m
Therefore,
457 nm = 457 nm × 1×10¯⁹ m / 1 nm
457 nm = 4.57×10¯⁷ m
Thus, 457 nm is equivalent to 4.57×10¯⁷ m
Finally, we shall determine the frequency of the blue light as follow:
Wavelength = 4.57×10¯⁷ m
Velocity of light = 3×10⁸ m/s
Frequency =?
Velocity = wavelength x frequency
3×10⁸ = 4.57×10¯⁷ × frequency
Divide both side by 4.57×10¯⁷
frequency = 3×10⁸ / 4.57×10¯⁷
frequency = 6.56×10¹⁴ Hz
Therefore, the frequency of the blue light is 6.56×10¹⁴ Hz
