3H2+N2→2NH3
here h2 H2 is limiting reagent
6moles of H2 will give 4moles of NH3
V of NH3 produced=22.4*4L
Answer:
False because liquids are more closly packed than Gases
Explanation:
Answer:
83 g
Explanation:
Step 1: Write the balanced equation
2 Fe + 3 S ⇒ Fe₂S₃
Step 2: Calculate the moles corresponding to 95 g of Fe
The molar mass of Fe is 55.85 g/mol.
95 g × 1 mol/55.85 g = 1.7 mol
Step 3: Calculate the moles of S needed to react with 1.7 moles of Fe
The molar ratio of Fe to S is 2:3. The moles of S needed are 3/2 × 1.7 mol = 2.6 mol
Step 4: Calculate the mass corresponding to 2.6 moles of S
The molar mass of S is 32.07 g/mol.
2.6 mol × 32.07 g/mol = 83 g
Answer: 280dm3
Explanation:Please see attachment for explanation
Answer:
The density of an iron bar is 8 g/cm3
Explanation:
The density (δ) is the ratio between the mass and the volume of a compound:
δ=m/v= 120 g/15 cm3= <em>8 g/cm3</em>
