Answer: The answer is K3PO4(s) → 3K+(aq) + PO43–(aq) since water-soluble ionic tripotassium phosphate dissociates completely into K+ and PO43– ions when dissolved, that is, no K3PO4 remains in the solution. Carbonic acid H2CO3 and acetic acid CH3COOH are weak electrolytes since they are weak acids that do not completely ionize, while nonelectrolyte CH3OH do not dissociate into ions.
Hope this helps!

If it has a positive charge it is a cation if negative it is an anion .
I attached a chart that will help you know the charges of the elements
Answer:
A. Second
Explanation:
The S.I unit of time is in Seconds.
The S. I unit is known as the metric system is the most commonly used system of reporting scientific measurements in the world today. Other units are the imperial units.
It is the international system of unit used in almost all countries. The seven basic SI units are:
Quantities Units
- Length meters(m)
- Time seconds(s)
- Amount of substance moles(mol)
- Mass kilograms(kg)
- Luminous intensity candela(cd)
- Temperature kelvin(K)
- Electric current ampere(A)
The SI unit of time which measures the duration of an activity or event is therefore given as seconds(s)
