Answer:
Explanation:
We classify the behaviours of electrolytes based on their electrolytic conduction. This is what makes them breaks down when in aqueous solutions with water.
A strong electrolyte is one that ionize completely when in aqueous solutions. Their ionization can be shown below using appropriate chemical notation:
An example of a strong electrolyte is NaCl:
NaCl
→ Na⁺
+ Cl⁻
Such reactions have a single forward arrow. Since they ionize complete, they have a large amoung of ions present in their aqueous form and would readily conduct.
A weak electrolyte is made up of compounds that ionize partially or slightly in their aqueous solution. The amount of ions produced per mole of compounds is relatively small compared to those of strong electrolytes. Examples ae organic acids, weak bases, and water. This ionization is shown below for methanoic acid:
HCOOH
⇄ HCOO⁻
+ H⁺
This sort of reaction is an equilibrium reaction. This is why we have the double arrow.
None electrolytes do not ionize at all in aqueous solutions and they produce no ions.

Answer:
1. Proton = electron if the element is not in an ionic state
proton = atomic number
N=9.03 x 10^ 23/6.02 x 10^23
n= 1.5 Mol
Explanation:
Because they share a similar composition, similar chemicals affect their structures in positive or negative ways. For example, fluoride – a staple in many dental practices – strengthens both enamel and eggshells and helps protect them from acids. Acids weaken and break down both substances. Scientists find this particularly concerning given that the ocean is growing increasingly acidic. They fear this may weaken the eggs of some marine species and harm their chance of survival. Most dentists recommend limiting aggressively acidic foods and beverages such as soft drinks.
