Answer #1

Coca Cola, like any other cola contains H3PO4 (Phosphoric acid), which will trigger coagulation of the milk proteins. Thus the milk solids will separate out from the water part (whey).

The above process will take some time at normal room temperature (say 4-6 hrs), but will be much faster when hot or boiling milk is used (NOT SURE THOUGH HOW SAFE IT WILL BE).

Another chemical reaction will take place, though very unlikely ti be vissible in all that fizz, is the precipitation of calcium of the milk as calcium phosphate.

Ca2+ + PO43- ------> Ca3(PO4)2

I have a linear regression project for class and am having trouble doing the T-test. I gathered data and now I'm just wondering how I would determine my hypothesis. Is it based on a p-value, do I have to find the t-statistic? I'm confused as in given problems the hypothesis is given? I know the level of significance is .10, so would that be my hypothesis (ho: beta =.10)?

If S(n) denotes the sum of digits of n, how can I prove that for any n, the sequence n, S(n), S(S(n)),... eventually becomes constant? I understand that this is essentially just finding the digital sum of n, but I am having hard time figuring out how I would formally prove this. Any help is appreciated! Thanks!

Should you be able to see a bacteriophage on an inoculation loop? For class, I am working on isolating a bacteriophage and I feel at times confused on what I should be expecting. I labeled the clear zones that are suspected bacteriophage and when I rested my inoculation loop on top of the area, I see nothing and feel nothing (I don't know what I expected, but it just makes me apprehensive that I'm not doing this right?) I, then,...
