Answer:
Electrochemical Cell
Explanation:
An electrochemical cell is a device that can generate electrical energy from the chemical reactions occurring in it, or use the electrical energy supplied to it to facilitate chemical reactions in it. These devices are capable of converting chemical energy into electrical energy, or vice versa.
If we have 6.68% NaClO, it is the same as saying--> 6.68 grams NaClO= 100 mL of solution. we can use this as a conversion.
800. mL (6.68 mL/ 100 mL)= 53.4 mL
solution = solute + solvent
solute= NaClO
solvent= H2O
solvent= 800-53.4= 747 mL of H2O
so, we you need 53.4 mL of NaClO and 747 mL of water or 53.4 grams of NaClO and 747 mL of water
Dang bro that stuff is really hard I’m defiantly on a lower grade lol

Electrolytes are those which dissociates in solution and produces ions.
Ions can carry current,so Electrolytes conduct electiricity.
And non electrolytes are those which do not dissociate in solution and doesnt produce ions.
Since non electrolytes do not produce ions they cannot conduct electricity.
<u>Hence the right option is:</u>
B) Non-electrolytes dissolve and do not dissociate in water providing no charged ions to conduct electricity.
