For the following reaction, the equilibrium constant Kc is 0.80 at a certain temperature. If the concentration of NO(g) and NOBr

velikii [3]

Answer:

[Br₂] = 1.25M

Explanation:

2NO (g) + Br₂ (g) ⇄ 2NOBr (g)

Eq 0.80M ? 0.80M

That's the situation told, in the statement.

Let's make the expression for Kc

Kc = [NOBr]² / [Br₂] . [NO]²

Kc = 0.80² / [Br₂] . [0.80]²

0.80 = 1 / [Br₂]

[Br₂] = 1 / 0.80 → 1.25

4) A granola bar has a mass of 42.9 g and the granola bar contains 26.20% honey

nata0808 [166]

Answer:

The percentage of honey in one granola bar is 26.02 percent.

Explanation:

The weight of 1 granola bar is 42.9 grams. The grams of honey that is present in one granola bar is equal to 26.02 percent of 42.9 = 11.16 g

Now the amount of honey in the factory is given as 189.5g the weight of total granola bars would be

$= 42.9/11.16 x 189.5= 728.25$

So no. of granula bars $=728.25/42.9 =16.9$ that can be Approximated to nearly 17

Now if one box has 6 bars then 17 bars will have to fit inside three boxes
