A classic chemistry class demonstration is the burning of magnesium ribbon with a
Bunsen burner. In this demonstration, two chemical reactions are occurring: the
burning of methane gas and the reaction between oxygen and magnesium. Of the
two reactions, what is the only limiting reactant?

Answer:

The only limiting reactant is the magnesium.

Explanation:

According to the 2 reactions that occur, oxygen intervenes in both.

2 Mg + O2 -----> 2 MgO + energy

CH4 + 2 O2 ------> CO2 + 2 H2O

Magnesium is the only limiting reagent in both reactions since it is the only one that is completely consumed, and as can be seen in the chemical reaction, 2 moles of magnesium and only 1 mole of oxygen are needed to react.

The only limiting reactant is magnesium.

Limiting reactant:

As per the 2 reactions that arise, oxygen intervenes in both.

So,

2 Mg + O2 -----> 2 MgO + energy

CH4 + 2 O2 ------> CO2 + 2 H2O

Magnesium shows only limiting reagent in both reactions because it is the only one that is finished consumed, and as can be seen in the chemical reaction, 2 moles of magnesium and only 1 mole of oxygen are required to react.
