1 What was the formulae of the metal T?n how to do that
2 What will be (needed to produce/produced by the hydrolysis) of the ester
(where the 2 blanks were given)
3 What was the test to show that both lactic acid and acrylic acid contained the COOH group
I hope i'll get the answers soon
Thanx.

i wrote t3po4
hydrolysis of an ester the corresponding alcohol n acid is formed
test i wrote red litmus turns blue
--- End quote ---
i wrote T3(po4)2 because the wen the volume was 2 the height was 4 so the height was double the volume so 2

kim v r rite. i also wrote T3(po4)2
heat619:
In the 2 blank questions i wrote first hydroxyl then carboxyl, then i noticed 'an' which means it must start with a vowel. I ignored that then continued then in the last part of the question they ask u how could u show that both contained acid group,so i thought about that and changed my answers to acid and alkanol......wat do u think??????:S:S:S:S
sweetsh:
What's alkanol?
