Question

When the following equation for a reaction, which occurs in acidic solution, is
correctly balanced using the smallest possible whole numbers, the coefficient of H+
is:
Sn + NO2- SnO2 + NO

Answer 1

Answer:

Sn + HNO3 = SnO2 + NO2 + H2O

BALANCED:

Sn + 4HNO3 → SnO2 + 4NO2 + 2H2O

Tin + Nitric Acid = Tin(IV) Oxide + Nitrogen Dioxide + Water
