Answer:
The answer is 1. A type of acid that completely reacts with water.
Explanation:
A strong acid dissociates completely in water to release hydrogen ions as the only positive ions.
This is the simple definition of Arrhenius acid.
Answer:
TRUE
Explanation:
An Equipment grounding conductor are used to ground a non current-carrying metallic parts of any equipment. Its main function is to keep the equipment close to the ground potential as possible and is also allows a safer path for the ground-fault current to flow. If the equipment is grounded, all the excess current will go to the ground and will not damage the equipment.
Hence the answer is TRUE.
Answer:
False: <span>The major component in a solution is called the Solvent.
Explanation:
Solutions are the Homogeneous mixtures of two or more substances. Mainly the components are divided into two catogories....
1) Solvent:
The component which is the major or which is present in large amount is called solvent.
Example: In water salt solution water is the solvent.
2) Solute:
</span>The component which is the minor or which is present in less amount is called solute.
Example: In water salt solution salt is the solute.
Idk but here something that made my day
Answer:
This will be the balanced half reaction:
NO₂(g) + H₂O (l) → NO₃⁻(aq) + 1 e⁻ + 2H⁺ (aq)
Explanation:
In acidic medium, the redox balance has to be done as this way.
As it is an oxidation, we know that oxidation state has increased.
NO₂(g) → NO₃⁻(aq) + 1 e⁻
Nitrogen in NO₂ acts with +4; in the nitrate, N acts with +5
The nitrogen has released 1 electron.
As we are in acidic medium, we must complete with water, in the same side, as we have less oxygens and in the opposite side, with protons to balance the H. This will be the balanced half reaction:
NO₂(g) + H₂O (l) → NO₃⁻(aq) + 1 e⁻ + 2H⁺ (aq)
