so, what weren some of the answers in the exdecel paper?

of unit 1,2,3?

1) in unit 2 where you calculate formaultion, did you get a negative or positive number? i got a negative because the products was on the left hand side and what it dissociates into was on the right hand side...

2) what was the plan on the last question of 3b? i put the -OH test? and primary will be faster than secondary etc...

3) Na2O + h2o -> ?

4) why couldnt you use HCL in a volmetric flask?

5) 155 +- (91/100%)?

how do you do this? i got Mn at the end

i cant believe i lost a mark though in unit 1

it was a water molecule i think and it asks for the bond angle

i knew it was a bend shape and guess 104 degrees

than at the very last second i crossed that out and put 74

>_<
