Answer: conducts electricity and heat efficiently, resists melting at high temperatures.
Explanation: Ionic compounds are formed by transference of electrons and leads to generation of cations and anions which are held by strong coloumbic forces. eg: NaCl
Ionic compounds when dissolved in water dissociates into ions and thus are good conductors of heat and electricity.
They are conductors not insulators.
They have very high melting points as they are held by strong coloumbic forces.
They dissociate into ions when dissolved in water.
Burying all of the methanol results in a hotter temperature so because flaming is attempting to ignite the dried salts.
That's because as the methanol is eaten to the finish, the flame approaches the dry salts and attempts to ignite them.
It is therefore critical to extinguish the flame even before methanol is entirely consumed.

For most non-electrolytes, the Van’t Hoff Factor is essentially 1.
Answer:
620.71 L the final volume of the balloon.
Explanation:
Initial volume of the gas in the balloon= 
Initial pressure of the gas in the balloon= 
Initial temperature of the gas in the balloon= 
Moles of gases = n
...[1]
Final volume of the gas in the balloon = 
Final pressure of the gas in the balloon = 
Final temperature of the gas in the balloon = 
Moles of gases = n
...[2]
[1] = [2]
620.71 L the final volume of the balloon.
