These are 3 assumptions that i know for a fact. Hope this helped.
1.Gas particles are continuous, rapid, random motion. They therefore possess kinetic energy, which is energy of motion.
2.There are no forces of attraction between gas particles.
3.The temperature of a gas depends on the average kinetic energy of the particles of the gas.
The compound that could serve as a reactant in the neutralization reaction is H2SO4
Explanation
Neutralization reaction occur between an acids and a base. H2SO4 ( sulfuric acid) is a strong acid. It can be neutralized by strong base such as NaOH ( sodium hydroxide)
Example of neutralization reaction is
2NaOH + H2SO4 → Na2SO4 + 2H2O
I have written the answer in the comments i hope it will be helpful to you ......
It is false that 1 mole of nacl(s) has a greater entropy than 1 mole of nacl (aq).
this is because nacl(aq) is in aqueous state while nacl(s) is in solid state. Nacl(aq) has greater entropy than nacl(s) because in
aqueous state their is increase in entropy. the entropy of the two ions in water has greater entropy than the solid nacl.
