determination of atomic mass


Reaction is M(s) + H3O=M(aq) + H2 + H2o

then in burrete Hcl was also added for rection
Then for diffusion later NH3 was added which will react with Hcl prev added plz help anyone ASAP?

would the conc of HCl used in this reation will affect result?
H2so4 instead of Hcl use will affect the volume ?

If NH3 is used before HCl in second part of reaction will it affect the reaction

will high temp affect the reaction of second part

Um, H3O ? Not something likely to be found on stockroom shelves.

Or are you trying to say H3O(+) meaning a hydrated proton, the hydronium ion?

The rest of your question is even less clear.

Thats likely the reaction given in a lab handout. Not exactly sure what you are always asking..
but to answer your question.. concentration (molarity or normality) would not effect the result, just the amount you needed to use
h2s04 would effect the volume. you would need to use half as much h2SO4 as HCL. HCl is monoprotic, sulfuric acid is not.
