i am not sure how you would approach this question. i tried writing out neutralisation reactions for each of the substances but i'm nowhere near getting the answer, could someone pls help?

Have you taken into consideration the molar ratio e.g if 2 moles are produced etc?

yup, that's why i tried writing them out, CO2 doesn't have any coefficient in front of any of them, and the HCl:CO2 ratio is the same for (a) and (c). do i have to apply the molar ratio elsewhere?

B and d produce co2

Wait I just realised what u said, yeah b and d produce the same moles of co2

they all produce co2 though, they're all carbonates or hydrogen carbonate salts, but the HCl:CO2 ratio is 1:1

Ohh I just realised, each is 1 g so convert that into moles for each and some will have more moles than other meaning more co2

oh i see, i did what you suggested and ending up getting the correct answer, thanks !!
