2 C2H2 + 5 O2 --> 4 CO2 + 2 H2O

2.35 mol C2H2 - x mol O2
2 mol C2H2 - 5 mol O2

$x = \frac{2.35 \times 5}{2} = 5.875 \: mol$
answer: 5.875 mol

S + 2e⁻ → S²⁻ (sulfur will gain electrons)

Mg - 2e⁻ → Mg²⁺ (magnesium will lose electrons)

Magnesium is a metal which tends to give electrons which are received by the sulfur, which is a nonmetal and tends to gain electrons.
