IDK JUST NEED ANSWERS,BTW IM DUMB
Answer:
Percent yield = 61.5%
Explanation:
Given data:
Moles of hydrogen = 2.00 mol
Actual yield of ammonia= 0.80 mol
Percent yield = ?
Solution:
Chemical equation:
3H₂ + N₂ → 2NH₃
Now we will compare the moles of ammonia with hydrogen from balance chemical equation:
H₂ : NH₃
3 : 2
2 : 2/3×2 = 1.3 mol
Percent yield:
Percent yield = Actual yield / theoretical yield × 100
Percent yield = 0.80 mol /1.3 mol × 100
Percent yield = 0.615 × 100
Percent yield = 61.5%

When you heat an atom, some of its electrons are "excited* to higher energy levels. When an electron drops from one level to a lower energy level, it emits a quantum of energy. ... The different mix of energy differences for each atom produces different colours. Each metal gives a characteristic flame emission spectrum.
