Answer to Question #276769 in Chemistry for michelle

Question

Which of the following is the correct formation equation for ethanamine?

1. 4C(g) + 7Hâ‚‚(g) + Nâ‚‚(g) ---> 2Câ‚‚Hâ‚…NHâ‚‚(g)
2. C(g) + Hâ‚‚(g) + Nâ‚‚(g) ---> Câ‚‚Hâ‚…NHâ‚‚(g)
3. 4C(s) + 7Hâ‚‚(g) + Nâ‚‚(g) ---> 2Câ‚‚Hâ‚…NHâ‚‚(g)
4. C(s) + Hâ‚‚(g) + Nâ‚‚(g) ---> Câ‚‚Hâ‚…NHâ‚‚(g)

Answer 1

Answer: "3"

4C(s) + 7H₂(g) + N₂(g) → 2C₂H₅NH₂(g)

To be more precise in the answer, it is:

2C(s) + (7/2)H₂(g) + (1/2)N₂(g) → C₂H₅NH₂(g)
