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
True
the definition of matter is any substance that has mass and takes up space.
The answer to your question is option 1. I hope this has helped.
Answer:
B) diffraction
Explanation:
A smooth pane of glass does not diffract light. A light passing through a smooth pane of glass may be absorbed, reflected or transmitted.
Diffraction only occurs with special types of glasses embedded with a diffraction grating and are called super prisms. Diffraction glasses use a a gradient lens which is able to separate light into all the colors of the rainbow.
Recall that diffraction is the separation of white light into its component wavelengths.
