Question

10. Balance the redox equations
a) SnO₂ + H₂ → Sn + H₂O

Answer 1

Its simple,

Step-by-step explanation:

The reaction will be as follows:

2SnO2 + 4H2 -->2Sn + 4H2O

The no. Between the elements are at the bottom.

Answer 2

SnO2 + 2H2 → Sn + 2H2O

Step-by-step explanation:

Cassiterite + Tritium = Tin + Water

1 mole of Cassiterite [SnO2] reacts with 2 moles of Tritium [H2] to form 1 mole of Tin [Sn] and 2 moles of Water [H2O]
