Answer:
The cathode of a spontaneous electrochemical cell is the cell in which metal cations undergo reduction. The electrons are supplied by the anode. Without much thought, we can conclude magnesium is much less favorably reduced than gold.
Answer:- The wavelength is and the right option is D.
Solution:- Wavelength is inversely proportional to the frequency and the equation is:
where, is the wavelength, c is the speed of light and is frequency.
Frequency is and the speed of light is .
Since,
So,
Let's plug in the values in the equation:
Hence, the right option is D) .
the branch of science concerned with the substances of which matter is composed, the investigation of their properties and reactions, and the use of such reactions to form new substances.
