The substances that are added in the funnel are bromoethane or CH3CH2Br, water and hexane. The density of the bromoethane is given as 1.460 g/mL, density of water would 1 g/mL and hexane would have a density of 0.660 g/mL. Assuming that these substances are immiscible in each other, adding them in a funnel would form three layers. The substance with the highest density would be in the lowest layer which is bromoethane. In the middle layer, water could be found. Lastly, hexane would be found on the uppermost layer since it is the substance that has the lowest density of the three.
Answer: 
is 1155 kJ
Explanation:
According to first law of thermodynamics:
=Change in internal energy
q = heat absorbed or released
w = work done or by the system
w = work done by the system=
{Work done on the system is positive as the final volume is lesser than initial volume}
w =
(1kcal=4.184 kJ)
q = +1.1 MJ = 1100 kJ (1MJ=1000kJ) {Heat absorbed by the system is positive}
Thus is 1155 kJ
Answer:
The range of variation under which a species can function and reproduce is called its tolerance range.

PLZZZ MARK ME BRAINLIESTTTTT
Make sure you have recycling bens in classrooms and in hallways. remind the teachers to keep on the students so they will get in the habit to recycle. This could reduce garbage and increase recycling! hope it works for you! :)
The salt bridge prevents the direct mixing of one half-cell solution with the other and allows ions to migrate from one half-cell to another.
