I didn't add too much CuSO4 -_- there was an amount we were supposed to put. =P Yes. I knew that about the Biuret's but the result for negative was supposed to be blue =S And it was BROWN. So yeah. It buffled me. So if eggwhite had a reducing sugar, would it have a brickred precipitate too...

I can't seem to figure out why the test came out as BROWN. I've been researching for HOURS and I can't find out why. I'm not asking any of you to give me an answer, but PLEASE throw me a hint. PLEASE. I heated the egg to 37C by the way.

speaking of biuret's, is there a time when this test would give a brown result? I've been researching for AGES. oh PLEASE help a humble student ='O

=O I thought of a red hammer! ;-; Can someone explain it to me? Dammit, my brain is average.

Oh yeah. I just learned that. 5N north + 6N east = 25 +36 = square root of 61 north east

Oh yes. Just add the two vectors. Like 5N east + 6N east = 11 N east.

We did the first condition of equilibrium. I'm not familiar with i, j vectors. I'm not too familiar with magnitude. Basically, I entered a three month old physics class and I just... fell into this.

And probably the rest of the lessons I missed. We were asked to research stability and equilibrium. So far, I know that equilibrium is a state an object is in when no unbalanced forces are acting upon it. http://www.physicsclassroom.com/Class/vectors/U3L3c.html I got lost when I read...
