Okay, I did a lab in class, but I'm having a little trouble with answering the questions about the lab... so your help would be much appreciated.

Okay, so first I added NH4OH, AgNO3 and glucose to a test tube.I saw that silver was coating the inside of the test tube, but the question is:

1. *Explain how the presence of glucose allowed this coating to form*

I thought the reaction of NH4OH and AgNo3, would produce NH4NO3 and AgNo3 (a precipitate), but apparently ther's more to it. I just really don't know where to add the C6H12O6 into the equasion. I don't need the equasion, I just need to understand what glucose has to do with it.

And I also have another question....
I added 5ml of Benedict's solution (it detects reducing sugars such as glucose and fructose) to 5 test tubes. THen to each of those 5 test tubes I added 8 drops of 2% glucose solution. I then heated the mixtures for ...

Guaranteed "best answer" to the most helpful answer.

Thanks in advance

In physics it is important to use mathematical approximations. Demonstrate that for small angles (<20 deg) tan x ~sin x~ x=pi*x'/180 deg where x is in radians and x' is in degrees. What is the largest angle for which tan x may be approximated by sin x if the error is to be less than 10.0%

Please show work.

I am already very bad at math when it comes to hw and sometimes understanding the equations. How can I understand it better or at least memorize the equation formulas for the test? What is your method? Or is it the only way to just read the equation over and over and memorize it? I know that is a bad way...but I am not born for math....the harder stuff anyways!!!
