<h3>What is half cell reaction?</h3>
A half-cell reaction is either an oxidation reaction in which electrons are lost, or a reduction reaction where electronic are gained.
The reactions occur in an electrochemical cell in which the electrons are lost at the anode through oxidation and consumed at the cathode where the reduction occurs.

Answer:
The analogy that best describes is "The planets go around the sun."
Explanation:
The best analogy that suggests that electrons moves round the nucleus in an atom is the Bohr model. According to Neil Bohr, Based on Rutherford's model, he suggested that the extra nuclear part consists of electrons.
These electrons are in the spherical orbits called shells or energy levels around the nucleus.
The nucleus is the tiny massive center of the atom.
Transition of electrons takes place from one level to another.
Answer: 0.043g
Explanation:
chemical formular of perchloric acid is HClO4
no. of moles = mass / molar mass
n = m / mm
m = n x mm
n = 4.25 x 10^-4 mol
m = ?
mm = 1 + 35.5 + (16 x 4) = 100.5g/mol
m = 4.25 x 10^-4 mol x 100.5g/mol
m = 0.043g
Exosphere, thermosphere, mesosphere, stratosphere, and troposphere
That would be the e
