A sealed 1.0 l flask is charged with 0.500 mol of i2 and 0.500 mol of br2. an equilibrium reaction ensues: i2 (g) br2 (g) 2ibr (

g) when the container contents achieve equilibrium, the flask contains 0.84 mol of ibr. the value of keq is ________.

The value of Keq = 110

Let's know how to get it :


According to the equilibrium reaction equation :


I2(g) + Br2(g) → 2IBr(g)


now we need to get the value of Keq


when the Keq expression is:


Keq = [IBr]^2/ [I] [Br]


when we have [IBr] at equilibrium = 0.84 so we need to get [I] &[Br] at equilibrium .


when [Br2] = [I2] = 0.5 - 0.84 / 2


= 0.08 M


so, by substitution


∴ Keq = (0.84)^2/(0.08)^2


= 110

Which type of substance is soft, has a low melting point, and is a poor conductor of electricity
In-s [12.5K]

Answer:

Covalent compounds have low forces of attraction between their molecules (i.e. one H2O molecule isn't as attracted to another H2O molecule than the oppositely charges ions are in an ionic compound). Little energy is needed to break their bonds, therefore they have low meting points. Hope this is what you are looking for!

What is the density of a piece of metal in g/cm3 if its mass is determined to be 42.20 g and it is in the shape of a cube, with
maria [59]
It's a cube so the volume = edge^3
Volume = 2.5^3 cm^3 = 15.625 cm^3

density = mass / volume = 42.20 / 15.625 = 2.70 You have 3 places of accuracy.

density of object = 2.70 grams / cm^3 <<<<=== answer.
