Question

Which reaction represents an unbalanced neutralization reaction?



A. Na + H2O NaOH + H2
B. HNO3 + NaOH NaNO3 + H2O
C. NaNO3 + H2O HNO3 + NaOH
D. H2O H2 + O2

Answer 1

D

Answer 2

I think

Answer 3

which reaction reacts an acid (which must always start with an \(H^{+}\) ion) and a base (which almost always ends with a \(OH^{-1}\) ion) to produce a salt and water?

Answer 4

NaOh

Answer 5

I see only one neutralization reaction and looks balanced to me

Answer 6

in this question i think we would be considering h2o as source of OH^(-)
as per that rxn a b and c can be considered as neutralisation rxns but all the three are balanced. The fourth reaction is neither neutralisation nor balanced therefore the answer should be (D).
