oxidation-reduction

I am having trouble with this question: I want to know if I have the correct answer (my answer is at the bottom. Observations: i) A reacts spontaneously with 1 mol/L BNO3, 1 mol/L D(NO3)2 and dilute sulfuric acid. A does not react with 1 mol/L C(NO3)2 ii) B does not react spontaneously with any of the 1 mol/L solutions above or with dilute sulfuric acid. iii) C reacts spontaneously with dilute sulfuric acid and with 1 mol/L solutions of all the other metallic salts. iv) D reacts spontaneously with 1 mol/L BNO3. It does not react with dilute sulfuric acid. a) Use the observations and arrange the following five reduction half-cell reactions in order, the one with the ... click for more

The definition which is used in everday chemistry. Quite useful in understanding chemistry and mostly wrongly understood.

IUPAC WHAT DOES IT MEAN .

EXPLAIN AN OBSERVATION

When glass is heated, a yellow flame is observed around the point of heating. What does the yellow flame indicate? Why is it observed when glass is heated? I think it indicates the spectrum of the silicon in glass & occurs when the glass is heated because the heat energy excites the electrons in the glass.

OLEIC ACID

The chemical formmula for oleic acid is CH3(CH2)7CH:CH(CH2)7COOH. What would be a balanced equation for the complete oxidation of one mole of oleic acid?

Restaurant- Boling Stones

I have a question that I found in a text book, can anyone help me answer it. It seems to be safe. Some of you are concerned with the fact that the operator of a vietemese restaurant used some stones as "boiling chips" in the pots where they cook food. Please provide a paragraph to provide rationale to support your (or no) argument/concerns with regards to the boiling stones (/3) This is intended as a "critical thinking" exercise; instructors are the target audience.
