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%
The chart is about atomic structure: at the top, the left box is "nucleus" and the right is "electron cloud".
On the left, under nucleus, the two boxes are: "protons" on the right and "neutrons" on the left. Under proton is elements which is given and under neutrons, it is "isotopes".
On the right, under electron cloud, the next box is "electrons" and then the lower box is "ions".
The mass of electrons , i just did the same test and got it right
Answer:
O the molecular formula
Explanation:
The true ratio of atoms in a molecule or formula unit is called the molecular formula.
The molecular formula of a compound shows the true number of atoms that are combining to form a compound.
For example, the molecular formula of water is H₂O.
- Empirical formula of a compound is its simplest ratio.
- When the number of atoms are divided by the smallest possible factor, it yields the empirical formula.
