Answer:
Energy transformation between mechanical energy and electrical energy
Explanation:
Generally, when the copper coil and the iron bar rotate in a circular direction, there is change in the magnetic flux, and as a result an electromotive force (also known as EMF) is generated. The induced electromotive force is the voltage produced due to the presence of magnetic force due to the rotation of the coil and iron bar. Thus, the energy transformation between mechanical energy and electrical energy occurs.
Answer:
b. One electron state is an anti-bonding orbital, which results in an absence of electron density between atoms.

Answer:
The answer to your question is 2 molecules
Explanation:
Unbalanced chemical reaction
H₂(g) + N₂(g) ⇒ NH₃ (g)
Reactants Elements Products
2 H 3
2 N 1
Balanced chemical reaction
3H₂(g) + N₂(g) ⇒ 2NH₃ (g)
Reactants Elements Products
6 H 6
2 N 2
From the balanced chemical reaction we conclude that when 3 molecules of hydrogen react with one molecule of nitrogen, 2 molecules of ammonia will be formed.
Answer:
Explanation:
Hello!
In this case, since the undergoing chemical reaction is:
We first need to identify the limiting reactant given the masses of nitrogen and hydrogen:
It means that only 0.647 moles of ammonia are yielded, so the resulting enthalpy change is:
Best regards!
