Please answer ALL QUESTIONS I DO NOT HAVE MORE POST QUESTIONS IN THIS CYCLE.

Type clearly and labeled as follows:

Use data to justify answers picture attached part C:

1- Did the presence of malonic acid have an effect on the result? Why do you think this might be the case? Use data to justify answer.

2- Did you find the temperature influenced the result? Why do you think this might be the case? Use data to justify answer.

3-Did you observed when you bubbled air through the mixtures in which there was an initial color change ? What accounts for this observation?

4- What is it important that the mineral oil form a layer on top of the glucose/ yeast/ methylene blue mixture in part C? Explain clearly

Explanation / Answer

1- Did the presence of malonic acid have an effect on the result? Why do you think this might be the case? Use data to justify answer.

As data states, addition of malonoic acid will form 3 layers, colloind, transparent, white foam, therefore, there is an obvious effect, since all other will have "no change"

2- Did you find the temperature influenced the result? Why do you think this might be the case? Use data to justify answer.

Tempearture will only cause rate change, i.e. how fast the reactions are occuring, but the table shows no effect in change (i.e.) the physical + chemical changes

3-Did you observed when you bubbled air through the mixtures in which there was an initial color change ? What accounts for this observation?

Bubbling air through mix will most likely be a formation of an oxidation formation, this is mostly sen in the yeast/glucose/methylen/Water mix

4- What is it important that the mineral oil form a layer on top of the glucose/ yeast/ methylene blue mixture in part C? Explain clearly

The top layer must be an oxidized material, since no other note is added, it is impossible to state which, but the methylene turning to white/blue states a change
