Here's The Answer: <span> K = 50.2 = (2x)^2 / (0.1-x)^2
x = 0.078
so H2 eq = 0.022 M
Hope this helped! :D

1. So 27.3 g Fe is 0.4911 mol (27.3 / 55.58). 45.8 g O is 2.862 mol. Because of the stoichiometry, 3/4 as much oxygen as iron gets consumed. For the 0.4911 mol Fe consumed, 0.3683 mol O is consumed. 2.862-0.3863 = 2.4757 mol, or 39.6 g O is left.
2. Hydrogen is the limiting reactant for these quantities. 2/3 as much ammonia is produced as hydrogen is consumed, so for 5.0 mol H2, that's 3.33 mol NH3.
Make sense?
Answer:
d) tetrahedral
Explanation:
Given that the central atom is attached to the four group.
Number of bond pairs = 4
Number of lone pairs = 0
The formula is .
According to VSEPR theory,
The central atom has 4 bond pairs and 0 lone pair. Hybridization is sp³. The geometry is tetrahedral which has an angle of 109.5°.
Methane, posses a tetrahedral geometry as four atoms of hydrogen are attached to the central atom which is carbon.
Hence. D option is correct.
If this is wrong im sorry, Im gonna go with 8.
