If the standard reduction potential of a half-cell is positive, the reduction reaction is spontaneous when paired with a hydrogen electrode
<u>Explanation:</u>
- The relative standard reduction potential of the half-cell in which reduction occurs; more positive than the other half-cell.
- If the standard reduction potential of a half-cell is positive, the reduction reaction is spontaneous when paired with a hydrogen electrode.
- The reduction is a chemical process in which electrons are added to an atom or an ion; it always occurs accompanied by oxidation of the reducing agent.
- The reduction to happen the electrons gained by the material that is being decreased must be transported from the atoms of ions of a different material.
I don’t know if I’m right I’m taking a guess but isn’t it because energy comes from the sun and we can’t change the sun
Lewis Structures of Ammonium Ion (RED) and Chloride Ions (BLUE) are attached below.
Lewis structures are those structures which shows the environment of electrons in a molecule. These structures basically depicts the bonding electrons and non-bonding electrons also known as Lone pair electrons.
In attached structure it can be seen that the ammonium ion is made when nitrogen atom is forming four single bonds with four hydrogen atoms and the formal charge on nitrogen becomes +1. While, in case of chloride ion the chlorine atom has four lone pair of electrons and has a formal charge of -1.
Gasses the most abundant natural occurring gas is nitrogen which makes up 78% of the air.
False
Actual yield in a reaction is almost always less than the theoretical yield, primarily because losses of the substances involved may occur anywhere in an experiment. Otherwise, there can be so many possibilities that can be reasoned out depending on the reaction.
