Chemistry P1 and P2 today

i wrote the nitrate one i guess

I chose the nitrate salt too. The compound in the question itself was a nitrate thats why.

i chose because all nitrate are soluble so maybe no ppt would be formed

we had to right abt fermentation

I wrote abt fermentation too but it's wrong. We had to write abt oxidation.

as far as i can remember Ca(OH)2 comes in the category of alkalis.....

What was the question? If you tell me, I'll tell you the answer.
I knew the things inside out but didn't pay attention to the paper and questions.

i wrote abt oxidation br K2Cr2O7
relieved

i wrote NH4+ and NO3-

Same here....

i dont know but i guess i read the question carefully at that moment

It was What is another method of preparing Ethanoic Acid from Ethanol other than burning it with air.

If it was other than burning with air then the answer was oxidation by using an appropriate oxidizing agent such as potassium dichromate (VI).
I've screwed my paper just because I didn't pay attention to the questions. An old habit of mine.

On the bright side, you are the ONLY ONE so far who got that X wala question perfect.
I might lose all the marks in that particular question. Neither did i write the ions right nor the gas.

I wrote we would use Potassium Permanganate as a Catalyst and under 300C temperature.. We can convery ethanol to ethanoic acid... Was I correct?

it would have been nbetter if u did that mistake in school cux that wx what taught me to read the questions carefully

as a catalyst well i think u shouldnt have written that

 

[abd1336480007]

I chose both ways. What bout you guys?

i chøse both ways too but everyone says it is wrong

Well, I'm not tensed because I didn't know the things, I'm tensed because I knew all these things and didn't read the questions carefully!

KMNO4 is an Oxidizing agent.. I read that in a book that any oxidizing agent than oxidize ethanol..


and what was the mass of NaCl coming? my answer was 0.925 g

I did these mistakes in school as well, I just never consider it.
