a.epsom
b.gypsum
c.chilli saltper
d.ammonium chloride
guyx do make usre u know the chemical formuals for first three salts...
epsom-MgSO4.7H2OCan you post the formula for the first three ?
Thanks !Yes, sure.
ECAT and *MCAT.
Man, im so bad at rote-learning!epsom-MgSO4.7H2O
gypsum-CaSO4.2H2O
chili saltepre-NaNO3
Post it!The determinant question in PIEAS sample test. Can anyone solve it ?
Solve the determinant question in the maths section.
The answer is -6Solve the determinant question in the maths section.
Lol no. You cant afford to skip Conics. The 7th chapter is not that important though.Thanks HIMYM. I just figured it out now. Can I leave the last two chapters of FSC part II book ?
Oh you talking about chemistry? yeah nobody does those two chapters.Chemistry book*
uhm could you explain that again, didn't quite get itThe answer is -6
You see in such questions, you can end up wasting most of your time if you dont think wisely. 1st expand by 1st column. Since there is only one non zero entry in it, it'll be easier. After expansion you'll get a 4x4 determinant.
now expand by 4th row, because of the same reason (only 1 non zero entry)
Now that you have a 3x3 determinant, expand by 1st column. I guess you can do the rest
And final step, -2 x 3 = -6
Ah it's really hard to explain maths like this. Anyway i'll try again.uhm could you explain that again, didn't quite get it
