Can someone please explain why 16 is A
I put B because of the mole ratios of CO and H2

Thanks!

Because you can see from the graph, the err... dotted line with a negative gradient decreases about 2x as much in conc in comparison to the solid line. Thus we can assume that the dotted line is H2 (given the equation).
So H2 was added.

How about the indicator question ? How to do that ? I got C but apparently its D

All three indicators MUST be either colourless or yellow for the final solution to be yellow. The gaps between the two colours would be a mix of the two colours.

who cares, its ovvvvvveeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeerrrrrrrrrrrrr!! WOOOOOOOOOOOOOOOOOOO

I totally agree!

pretty sure water isnt an oxide so 15 isnt C, and it cant be D, cos Co2 isnt amphoteric, so its A

Can't be A, SO3 is acidic, not neutral.

15is definitely A, its the most correct answer

I'm hoping you guys are joking. By the way, water is HYDROGEN OXIDE.
