Why are solutions heated before evaporation?
well i THINK heating the solution will speed up the reaction in the solution before adding the precipitate since the final observation required is the precipitation. you dont add the reagent before heating since it may give a false observation after heating, it might not precipitate normally but since you've otherwise it might.

Purpose of adding NaOH to the mixture before taking the polarimeter reading?
To neutralize the solution and to prevent the complete hydrolysis of sucrose into glucose and fructose.
Why must the sugar solution be cooled before adding yeast?
It's not clear in what context this question is asked, but hot water can kill yeast.
Why beaker used to collect solution should be dry?
Beakers that will be used to collect solutions should be completely dry before use due the possibility of water being able to dilute the solution that will be placed inside of the beaker. If a beaker is not completely dry before collection of a solution, an inacurracy in data results may occur.
What is meant by simultaneous eigen state of operators?
What's meant is that the equation has multiple solutions all existing at the same time. In quantum, the observable solution of a state isn't determined until measurement, before that, the state is simultaneously in all solutions.
Why is NaOH heated before adding BaCl2?
By adding HCl, you can ensure the presence of the SO4(2-) ion.
What solutions did the Nazis have for killing people before the final solution?
Most of the solutions before the Final Solution were not killing. The Jewish question was what to do with the Jews, they had tried to get them to emigrate, they had tried to deport them, to slowly starve them, there were more suggested solutions, like sterilization, but the Final Solution was to outright murder them.
Why would you boil a potato in a biology experiment before adding solutions to it?
to make it more absorbent
What problems did the Nazi's have to deal with before they could carry out their final solution?
they had to try all of the other 'Solutions', hence the Final in the 'Final Solution'.

What is the purpose of adding NaOH to the mixture before taking the polarimeter reading?
It is to neutralize the solution and to stop the hydrolysis.
When might a speaker present solutions before explaining the problem in a problem-solution speech?
When the audience knows all about the problems
Why is the glucose solution boiled first before adding the yeast suspension?
The glucose solution is boiled then allowed to cool before you add the yeast because boiling water will kill the yeast.
Why is an aqueous solution usually first acidified with dilute nitric acid before adding aqueous lead nitrate?
To keep the kead nitrate in solution: otherwise it might precipitate lead.
Where can I get some online information about broadband internet solutions for my company?
Future Generations Technology has a great breakdown of broadband business solutions. Check their site for more information. HughesNet has some great broadband business solutions. My company consulted with them before adding broadband last year.
What must you do to determine weather a soluion is an exraneous solution?
If the solution, makes the denominator equal to zero, makes the expression of a logarithm or under a square root, a negative one. If there are more than one denominator, check all the solutions. Usually, we determine the extraneous solutions before we solve the equation.

To neutralize the solution and to prevent the complete hydrolysis of sucrose into glucose and fructose.
