Consider the following balanced chemical reaction:

2A + 4B → 3C + 4D

If 5 moles of A react with 6 moles of B, then which of the following accurately describes the limiting reagent and the amount of C formed​​​​​​?

1. A is the limiting reagent and 4.5 moles of C is formed
2. B is the limiting reagent and 4.5 moles of C is formed
3. A is the limiting reagent and 7.5 moles of C is formed
4. B is the limiting reagent and 7.5 moles of C is formed

What is the mass of ammonia (in grams) produced when 2.8 kg of dinitrogen quantitatively reacts with 1 kg of dihydrogen?

What is the limiting reagent when 97.5 grams of zinc sulphide undergo the reaction with 32 grams of oxygen gas?

2ZnS + 3O₂ → 2ZnO + 2SO₂ 
(Given: Molar mass of ZnS = 97.5 g mol⁻¹)
