The new lowered freezing point of the benzene mixture is determined as 2.4°C.
<h3>
Effect of impurities in freezing point</h3>
The presence of impurities lowers the vapour pressure of the solution since the concentration of the solution is increased.
Change in temperature of the new mixture = 0.613 x 5.5°C = 3.1 °C
New freezing point = 5.5°C - 3.1°C = 2.4°C
Thus, the new lowered freezing point of the benzene mixture is determined as 2.4°C.

<span>Electronegative.
Electronegativity is the tendency for an atom to pull more electrons. Fluroine is the most electronegative element, and the trend is up and to the right of the periodic table, with the exception of the noble gases.</span>
Answer:
40*c
Explanation: Higher the temp, the more kinetic energy
There are many safety precautions and rules you MUST follow during labs.
for this incident here is what you should do:
1)Notify your Instructor and partner
2) if the liquid is toxic (like not water or vinegar) then let your Instructor handle it properly, or follow your instructors orders (like if they say to put a towel over it or something like that)
3) Broken glassware, minus mercury thermometer, must be immediately cleaned up, do not use your bare hand, always wear gloves.
4)dispose of the broken glass properly and clean the liquid up (unless it is harmful, then let your instructor do it)
