Question

When 1 mole of tin(IV) oxide is heated with 2 moles of hydrogen gas, 1 mole of tin metal and 2 moles of water vapor are generated. SnO2 + 2H2 → Sn + 2H2O

Answer 1

The answer is "0.74".

Step-by-step explanation:

Moles of
`SnO_2 =0.74 \ mole`

`\bold{Given \ equation:} \\\\ SnO_2+2H_2 \to Sn+2H_2O`

The balanced chemical reaction will include 1 mole of
`SnO_2` react to the given 1 mole of
`Sn \ so,\ 0.74` mole of
`SnO_2` react to give 0.74 moles of Sn, therefore its moles of tin metal will be 0.74 moles.
