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.
Fire burning is a combustion reaction, which is a type of reaction that is always EXOthermic (meaning it gives off heat). When the carbon in the wood reacts with the oxygen in the air, it forms CO2 and H2O, releasing heat in the process that escapes the fire place and transfers out to the room.
As for the spread of heat:
“A fire can spread by radiation when the heat travels through electromagnetic waves in the air”

Answer:
true because the bonds cannot be broken down
1 mole of gas occupies 22.4 L at STP. Therefore, each gas has 1/22.4 moles and because the number of moles is the same, the number of molecules of each gas is also the same.
The least polar molecules are of N₂ and they will show the most ideal behavior out of all three of the gases.
