Answer:
9.62moles of NH₃
Explanation:
Given parameters:
Number of moles of nitrogen = 4.81moles
Unknown:
Number of moles of NH₃ = ?
Solution:
To solve this problem, we need to establish a balanced reaction equation:
N₂ + 3H₂ → 2NH₃
Now, we can solve the problem by working from the known to the unknown.
1 mole of N₂ produced 2 moles of NH₃
4.81moles of N₂ will produce 2 x 4.81 = 9.62moles of NH₃
There are two magnesium molecules or 4 atoms
Answer:
Na - 1 away from neon
Li - 1 away from helium
K - 1 away from argon
Cs - 1 away from xenon
Explanation:
We see this trend as group 1A elements are 1 away from noble gases and hence, have a valency of 1
Answer:
Fhe atomic mass is 16....
