it cannot be carboxyl..... ethanol cannot be an example of carboxyl
and ethanol is an alcohol ..... so therefore the answer is alcohol
Answer: The net ionic equation for the cobalt-silver voltaic cell is
Explanation: In cobalt-silver voltaic cell, one half of the cell consists of cobalt electrode immersed in solution ( which means that are present in the solution) and other half of the cell consists of the Ag electrode immersed in solution ( which means that is present in the solution)
The two electrodes are joined by the copper wire. The cobalt electrode acts as an anode and the silver electrode acts a cathode.
At anode, oxidation reaction takes place and at cathode, reduction reaction takes place.
At Anode :
At Cathode:
Net ionic equation:
Correct Answer is 1 i.e. Gamma rays—2 and radio waves—3
Reason:
1) In a hypernova, star<span> as similar to </span>nuclear fusion<span> converts lighter elements into heavy elements. If fusion is not capable of generating enough pressure to counteract gravity, star immediately collapses to form a </span>black hole<span>. During this process, energy will be released, along the axis of rotation to form </span>gamma-ray burst. Such gamma-ray burst was first detected using <span>Fermi Gamma-ray Space Telescope. Thus, gamma-ray is capable of providing information of gravity fields.
2) Radiowaves are capable of inducing transitions that requires less energies. These transition includes nuclear excitation and electron excitation (in rotational energy level). Depending upon the value to Jmax, it is possible to determine the temperature and </span><span>heat released by astronomical objects</span><span>

If a<span> student used 10 mL water instead of 30 mL for extraction of salt water from mixture, the extraction of salt will be lesser than compared to using 30 mL since less solute will dissolve in 10 mL.</span>
