I know its not the answer but i had to put something bc im jus setting this up im rlly sorry for the inconvenience but i looked it up n got a quizlet n the answer on there was 1.81x10^-4 if it helps
Answer:
See explanation
Explanation:
Iron exhibits two stable oxidation states, +2 and +3 states. The difference between FeO and Fe2O3 is that, in FeO, Fe is in the +2 oxidation state while in Fe2O3, Fe is in the +3 oxidation state
In FeO, iron looses two electrons which are gained by oxygen as follows;
Fe^2+ + O^2- -----> FeO
In Fe2O3, Fe looses six electrons while oxygen has gained six electrons as shown;
2Fe^3+ + 3O^2- ------>Fe2O3
Answer:
1.93 mol Ca
Explanation:
Use Calcium's molar mass to convert g of Ca into mol of Ca.
Answer:
The answer to your question is a) N₂ b) 3.04 g of NH₃
Explanation:
Data
mass of H₂ = 2.5 g
mass of N₂ = 2.5 g
molar mass H₂ = 2.02 g
molar mass of N₂ = 28.02 g
molar mass of NH₃ = 17.04 g
Balanced chemical reaction
3H₂ + 1 N₂ ⇒ 2NH₃
A)
Calculate the theoretical yield 3H₂ / N₂ = 3(2.02) / 28.02 = 0.22
Calculate the experimental yield H₂/N₂ = 2.5/2.5 = 1
Conclusion
The limiting reactant is N₂ (nitrogen) because the experimental proportion was higher than the theoretical proportion.
B)
28.02 g of N₂ -------------------- (2 x 17.04) g of NH₃
2.5 g of N₂ -------------------- x
x = (2.5 x 2 x 17.04) / 28.02
x = 85.2 / 28.02
x = 3.04 g of NH₃
