Answer: The freezing point of a 0.765 m solution of nitrobenzene in naphthalene is 
Explanation:
Depression in freezing point is given by:
= Depression in freezing point
i= vant hoff factor = 1 (for non electrolyte such as nitrobenzene)
= freezing point constant = 
m= molality = 0.765
Thus the freezing point of a 0.765 m solution of nitrobenzene in naphthalene is
Answer:
When iron sulfide is exposed to oxygen it reacts rapidly, releasing large amounts of heat.
Explanation:
i took this from my notes- so whatever aligns with that. sorry if this didnt help but i think its genuinely c heating
This is known as Rutherford's gold foil experiment. To align with J.J Thompson's Plum Pudding Model, he expects a beam of alpha particles to just pass through the gold foil undisturbed. However, some were deflected at certain angles. Alpha particles are positive, so it would just go straight through the nucleus, but will deflect if it hits the electrons. <em>Therefore, the answer is: </em><span><em>Particles that struck the nucleus went straight.</em></span>
