Asimple way to estimate whether a molecule is a strong electrolyte, a weak electrolyte, or a nonelectrolyte is to examine an equation that accurately describes its behavior in water. when examining the chemical equations, start by looking at the direction and type of reaction arrow. a chemical equation reported in the literature may include a forward reaction arrow (→), equilibrium reaction arrow (⇌), or reverse reaction arrow (←). next, determine whether ions are likely to be present and, if present, in what quantities they should be present.

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.

given:

mass of na = 115 g

excess cl2

to determine:

mass of nacl produced

explanation:

given reaction is-

2na(s) + cl2(g) → 2nacl(s)

since cl2 is in excess, na will be the limiting reagent

as per the reaction stoichiometry na: nacl = 1: 1

i.e. moles of na reacted = moles of nacl formed

now, # moles of na = mass of na/atomic mass

                                  = 115 g/23 g.mol-1 = 5 moles

therefore, moles of nacl = 5

molar mass of nacl = 58 g/mol

mass of nacl = 5 moles * 58 g.mol-1 = 290 g

ans: amount of nacl produced = 290 g

a boiling water reactor does not boil the water. a pressurized water reactor boils the water faster. a pressurized water reactor is heated directly by the core. a pressurized water reactor does not use fission.
