2. Balanced Chemical Equation
Reaction Type:
At completion of reactions:
Grams of nitrogen
Grams of hydrogen
Grams of ammonia
Transcribed Image Text:2. Balanced Chemical Equation Reaction Type: At completion of reactions: Grams of nitrogen Grams of hydrogen Grams of ammonia
N₂ (g) + 3 H₂ (g) → 2 NH3 (g) (This is LIMITING REACTANT: N₂ is the Limiting Reactant)
Grams of Product (List the Product and the Amount): 0.75168 g NH3
Reaction Type: Combination or Single Displacement (which is also called Oxidation-Reduction)

? g NH3 = 61.802 cg N2 x
LR
1 mol N₂ x 2 mol NH3 x 17.04 g NH3 =
28.02 g N₂

? g NH3 = 61.802 cg H₂ x
How much N2 remains in the vessel?

You will use the LIMITING REACTANT and determine how much H₂ was USED in the RXN.
2 mol NH3 x 17.04 g NH3 =
3 mol H₂
1 mol NH3
1 mol N₂ x 3 mol H₂ x 2.02 g H₂ =
28.02 g N₂
1 mol N₂
1 mol H₂
0.75168 g NH3 ******* THEORETICAL YIELD
3.3756 g NH3
1 g N₂
1 x 10² cg N2
Amount of H₂ Remaining in the Container = H₂ amount given - H₂ amount USED= 0.61802 g H₂ GIVEN 0.13366 g H₂ USED
= 0.48436 g of H₂--LEFT OVER = EXCESS
0.13366 g H₂
