The number of lone pairs that are most likely found on the central atom is zero. There are no lone pairs found on the central atom.
Answer:
3.0 L of NH₃
Solution:
The equation is as follow,
N₂ + 3 H₂ → 2 NH₃
According to equation,
67.2 L (3 mole) H₂ at STP produces = 44.8 L (3 mole) of NH₃
So,
4.50 L of H₂ will produce = X L of NH₃
Solving for X,
X = (4.50 L × 44.8 L) ÷ 67.2 L
X = 3.0 L of NH₃
The answer is A. PCl15 because a covalent bond is formed by two nonmetals bonding.
Explanation:
The given reaction equation is as follows.
The greatest molarity will be calculated as follows
=
= 0.00070584 mol/ml
or, = 0.70584 mol/L (as 1 l = 1000 ml)
The smallest molarity will be calculated as follows.
= 0.00070115 mol/ml
= 0.70115 mol/l
Now, we will find the average as follows.
= 0.703495
Now, half of the difference will be calculated as follows.
= 0.002
therefore, we can conclude that the resulting answer is 0.703 ± 0.002 mol/L .
