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.
Answer:
Not exactly sure what you mean by this, but "The average density of an object equals its total mass divided by its total volume."

Explanation:
1) If we have 1/2 OWLs of Snicker bars, then number of items or Snicker bars :
1 OWL = 7 items (given)

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)

We have 700 pencils.
3) If we have 2 OWLs of iron atom, then number of iron atoms :
1 OWL = 7 items (given)
of iron
We have 14 atoms of iron.
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.
