could you please do the same for chemistry paper 3 and biology paper 3

chem paper 3 is quite unlikely but I can try....bio paper 3 is not possible coz I did not take the bio igcse....

for the question asking for maximum speed i wrote= 10m/s is it right or wrong ? plz answer

Maybe 1 mark if the correct formula was shown....but not the whole 3 marks as 9 might have given u 2 marks but 10 is not even rounded so ..... sry :(

THANKSSSSSSSSSS ALOT.....now I got it we have to balance it without changing the numbers of reactants because question said 1 needs 8 ...so now I got it.
Thanks!
