neither a nor b is limiting
The one that runs out first in a reaction - is thoroughly accurate. There are quite a few other limiting reagents in limiting reactions - as well.
To determine the limiting reagent, first write the balanced chemical equation for the reaction. Then, calculate the moles of product that can be formed from each reactant. The reactant that produces the least amount of product is the limiting reagent.
MgCl2 would be the limiting reagent
The limiting reactant or reagent can be determined by calculating the number of moles of each reactant/reagent. Whichever is the lowest number of moles is the limiting reagent in the reaction, assuming that stoichiometry is 1;1
In the reaction between magnesium (Mg) and hydrochloric acid (HCl), the limiting reactant is the reactant that is consumed first, which determines the maximum amount of product that can be formed. To determine the limiting reactant, you would need to compare the moles of magnesium and hydrochloric acid to see which one is present in the lowest stoichiometric amount.

The limiting reagent is the reactant that is completely consumed first in a chemical reaction. To determine the limiting reagent in the reaction between sodium hydroxide and copper chloride, you would need to compare the moles of each reactant present and see which one is in excess and which one is limiting.
When barium sulfate is made, the limiting reagent is the one that is completely consumed in the reaction and determines the amount of product formed. In this case, if barium ions (Ba2+) and sulfate ions (SO42−) are the reactants, the limiting reagent would be the one that is present in lower molar quantity. The one in excess would be the one that is present in higher molar quantity. Without the quantities of each ion provided, it is difficult to determine which is the limiting reagent and which is in excess.
The Limiting Reactant is the smaller number once you compare the two reactants with one product. The product that you are comparing them both with must be the same. The Excess Reactant is the larger number, or the amount left over in the chemical reaction.

It is impossible a reaction without reactants.
To determine the expected yield of C2H4N2 from the reaction of CO2, NH3, and CH4, we first need to identify the balanced chemical equation for the reaction. Assuming the reaction is balanced, we would calculate the moles of each reactant (CO2, NH3, and CH4) and identify the limiting reagent. The limiting reagent will dictate the maximum amount of C2H4N2 that can be produced. Since specific stoichiometric coefficients are not provided, you would need to perform these calculations based on the balanced equation to find the exact mass of C2H4N2 produced.

The balanced reaction of cupric iodide and aluminum chloride is 3 CuI2 + 2 AlCl3 = 3 CuCl2 + 2 AlI3. This means that the limiting reaction is cupric iodide, because more of it is required than aluminum chloride.
The reagent needed to complete a reaction depends on the specific reaction being carried out. It could be a catalyst, solvent, substrate, or a specific chemical compound required for the reaction to proceed successfully. Consulting the reaction mechanism or the experimental protocol would help identify the necessary reagents.
