I am so curious to find out the answers so pls answer my following questions:

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.

there must have been different variant papers ?
