reaction betwen sodiumbisulphite and hydrogen peroxide
yes
The white you see is many microscopic bubbles of oxygen released by a reaction between the Hydrogen Peroxide (H2O2) and your saliva.
They are the same chemical.
Well, I would actually guess that there wouldn't be one, being that all you are doing is adding more of the same thing to the same thing. This is because if there was a reaction between hydrogen peroxide and hydrogen peroxide, it would happen all the time, as the molecules of hydrogen peroxide are always next to each other... (well not always, but you get the point) Hope this helps!
Its becomes a very reactive and explosive alcohol when it is oxidized. The hydroxide molecule in the alcohol steals Hydrogen from the peroxide and gives off three gasses; Hydrogen Dioxide, carbon dioxide and oxygen making the entire reaction very explosive. ch 4h h2o co2. Its very explosive because of the spontaneous release of hydrogen from the peroxide to equalize the hydroxide from the alcohol occurs faster with the presence of peroxide. Never oxidize an alcohol.
yes
Hydrogen Peroxide decomposes in oxygen gas and water.
There is no reaction between H2O2 and K2Cr2O7 because both are oxidants.

endothermic because it absorbs energy, and not releasing it
No reaction occurs between the acidified hydrogen peroxide and the other halide ions, because the hydrogen ions involved in both cases are in the same group. For a reaction to occur it needed to have an element that is more reactive than hydrogen.
Temperature
Yes, the mixture does get warmer! It is called an exothermic chemical reaction, which just means it gives off heat. It is the opposite of an endothermic reaction, which means it absorbs heat. The reaction between hydrogen peroxide(C2H2) and yeast produces oxygen. Hope this answers your question!
The false positive from the reaction of hydrogen peroxide and the inoculating loop would be caused by poor specificity. The formula for specificity is TN/TN+FP.
