Not all organic solvents are suitable for liquid-liquid extraction with an aqueous solution. list at least three such solvents; make sure each of the three bears a different functional group. your answer arises from a general rule regarding miscibility of organic molecules with water. what is the ""rule of thumb""?

temp rises, and expansion

answer: at 24 february, 2014 the population gets twice of its initial population.

explanation:

since we have given that

the population for alpha city, t years after january 1, 2004 is given as

first we find out the initial population, i.e. t=0,

so, our quadratic equation becomes,

according to question, we have said that if the population has twice its initial population, then it becomes

so, time taken to reach this above mentioned population is given by

now, we know that time can't be negative so, we take t=9.149 years.

hence, at 24 february, 2014 the population gets twice of its initial population.
