Consider the reaction. mc026-1.jpg At equilibrium at 600 K, the concentrations are as follows. [HF] = 5.82 x 10-2 M [H2] = 8.4 x
nadezda [96]

Answer:

2.1 x 10⁻².

Explanation:

  • Generally, the equilibrium constant (Keq) is the product of the concentration of the reaction products divided by the product of the concentration of the reaction reactants, each term is raised to a power equal to its coefficient in the balanced chemical reaction.
  • For the given reaction: 2HF → H₂ + F₂,

Keq = [H₂][F₂] / [HF]²,

Keq = [H₂][F₂] / [HF]² = [8.4 x 10⁻³][8.4 x 10⁻³] / [5.82 x 10⁻²]² = 2.1 x 10⁻².

1 OWL = 7 items (given)

\frac{1}{2}\times 7 items=3.5 items

We have 3.5 Snickers bars.

2) If we have 100 OWLs of pencils, then number of items or pencils :

1 OWL = 7 items (given)

100\times 7 items=700 items

We have 700 pencils.

3) If we have 2 OWLs of iron atom, then number of iron atoms :

1 OWL = 7 items (given)

Why are thermosoftening polymers not suitable for storing very hot food?
Alina [70]
When hot food is placed inside the polymers it will melt, this is because there is weak attraction between polymer chains and thermosoftening so they melt and break away the bonds holding them together.
