For the reaction , identify dihydrogen () as a limiting reagent in the following reaction mixtures:
- a
28 g of + 6 g of
- b✓
35 g of + 8 g of
- c
56 g of + 10 g of
- d
14 g of + 4 g of
35 g of + 8 g of
🧠 The Dihydrogen Bottleneck Haber's process () is a numbers game. You need three times as much Hydrogen () as Nitrogen (). If you have less than that, the Hydrogen is your Limiting Reagent. Test every mixture by comparing the Nitrogen "potential" to the available Hydrogen.
🗺️ Strategic Roadmap Step 1: Convert masses to moles.
- (a) + : Perfect balance ().
- (b) () + (): Need . We have . (Nitrogen limits).
- (c) () + (): Need . We only have . Hydrogen is Limiting.
