Answer:
Data supports significantly because we can use the testing(depending sample) before and after we use the same object to test the hypothesis.
You need to find the abundance. Then, multiply the abundance by 100, and add that to the mass for each isotope. Basically, for each isotope, take the percentage abundance and add it to the mass. Multiply each calculation of these together to get your average atomic mass,
The number of moles of H₂ that are needed to react with 2.0 moles of N₂ is 6.0 moles
<u><em>calculation</em></u>
N₂ +3H₂→ 2NH₃
The moles of H₂ is calculated using the mole ratio
That is from equation above N₂:H₂ is 1 :3
therefore the moles of H₂ = 2.0 moles x (3/1) = 6.0 moles
Answer:
Look at the picture.
Explanation:
For planar anion point group is D3h. For trigonal piramidal point group is C3v.
On picture 2 and 3 are the tables for each point group. Irreducible representations its the horizontal rows in tables. Where you see x, y and z it's translation of p-orbitals. Where you see R - it's rotations.
