Answer:
Most oxidation-reduction (redox) processes involve the transfer of oxygen atoms, hydrogen atoms, or electrons, with all three processes sharing two important characteristics: (1) they are coupled—i.e., in any oxidation reaction a reciprocal reduction occurs, and (2) they involve a characteristic net chemical change— .
The combustion reaction for butane is as follows ;
2C₄H₁₀ + 13O₂ ---> 8CO₂ + 10H₂O
Stoichiometry of butane to oxygen is 2:13
Number of butane moles reacted = 5.23 g / 58 g/mol = 0.090 mol
number of Oxygen moles reacted = 27.1 g/ 32 g/mol = 0.84 mol
we have to find which is the limiting reactant
if butane is the limiting reactant,
if 2 mol of butane reacts with 13 mol of O₂
then 0.09 mol of butane reacts with -13/2 x 0.090 mol = 0.58 mol
there are 0.84 mol of oxygen present but only 0.58 mol reacts therefore butane is the limiting reactant.
stoichiometry of butane to water is 2:10 = 1:5
the number of water moles formed = 0.090 mol x 5 = 0.45 mol
mass of water formed = 0.45 mol x 18 g/mol = 8.1 g
