The elementary reaction 2h20(g)< > 2h2(g)+o2(g) proceeds at a certain temperature until the partial pressures of h2o, h2, and o2 reach 0.0700 atm, 0.00200 atm, and 0.00600 atm respectively. what is the value of the equilibrium constant at this temperature?

4.9 x 10⁻⁶.

Explanation:

2H₂O(g) ⇄ 2H₂(g) + O₂(g),

'

P of H₂ = 0.002 atm, P of O₂ = 0.006 atm, and P of H₂O = 0.07 atm.

∴ The equilibrium constant (Kp) = (P of H₂)²(P of O₂)/(P of H₂O)² = (0.002 atm)²(0.006 atm)/(0.07 atm)² = 4.9 x 10⁻⁶.

b..

is the correct one

explanation:

covalent bonds form as valence electrons are shared between two atoms. lewis structures and structural formulas are common ways of showing the covalent bonding in organic molecules. formal charge describes the changes in the number of valence electrons as an atom becomes bonded into a molecule.

answer : a model is often used to explain and make things easier to understand when any scientific topic needs to be demonstrated and explained.

as in this case where a scientist wants to use a model to present the results of his detailed scientific investigation. he should do it as it will him to make the audience understand the concept in a much better way. also, it can be changed according to new scientific understandings.
