Consider the equations below. H₂ → 2H
CHA+HC2H5
C2H5 + HC2H6
When these equations are added together, what will the overall equation be?
C₂H4+H₂C₂H
H2 + CH4 + 2H + C2H5+ → 2H + CH3 + CHE
C2H4 +C2H4 + H2>C2H5 + C2H5

In a laboratory determination of the atomic weight of tin, a sample of tin is weighed in a crucible. nitric acid is added, and the reaction proceeds to give a hydrated tin(iv)oxide plus no2and h2o. the hydrated tin(iv)oxide is then heated strongly and reacts as follows: sno2.xh2o(s)sno2(s)+ xh2o(g)the sno2is finally cooled and weighed in the crucible. explain the effect on the calculated atomic weight of tin that would result from each of the following experimental errors: (a)considerable spattering occurs when the nitric acid is added to the tin.(b)the hydrated tin(iv)oxide is not heated sufficiently to change it completely to tin oxide.
