The ratio is 2:1. You need two moles of hydrogen for every mol of O2. The proportion would be written as
2:1::4:x
2/1 = 4/x Cross multiply
2x = 4 Divide by 2
x = 4/2
x = 2
You would need 2 moles of O2 to react with 4 mols of H2
The correct answer is option (a) i.e. the equilibrium constant is 0.0167
<span>
We know,
The equilibrium constant is kc = Concentration of product/ concentartion of reactants,
kc = [C][D] / [A][B],
Now,
kc= [4.00]*[4.0] / ( [9.60] * [10.00] ) = 0.166 </span>≈ 0.167
Thus, the equilibrium constant is 0.0167
Answer:
C. Glass
Explanation:
Amorphous solids have a non-crystalline structure and no order. In that case, Diamonds, Graphite, and Iron all have a crystalline structure and order. You are left with C as your answer.
This is because a helium atom is loath to give up its two electrons, which perfectly fill its only electron shell. ... Elements with shells that are already full and have no electrons to lend are called noble gases—and helium, the smallest of these, is considered the most inert.20 Mar 2018
