the reaction AB2C (g) <---> B2 (g) + AC (g) reached equilibrium at 900 K in a 5.00 L vessel. At equilibrium 0.0840 mol of

Verizon [17]

Answer:

k = 4,92x10⁻³

Explanation:

For the reaction:

AB₂C (g) ⇄ B₂(g) + AC(g)

The equilibrium constant, k is defined as:

$k = \frac{[B_{2}][AC]}{[AB_2C]}$ (1)

Molar concentration of the species are:

[AB₂C]: 0,0840mol / 5L = 0,0168M

[B₂]: 0,0350mol / 5L = 0,0070M

[AC]: 0,0590mol / 5L = 0,0118M

Replacing this values in (1):

$k = \frac{[0,0070][0,0118]}{[0,0168]}$

k = 4,92x10⁻³

I hope it helps!

How many moles are in a sample of Sodium that contains 1.806 x 1024 atoms?

Ad libitum [116K]

Answer: 3 moles Na

Explanation: To find the number of moles of Na, divide the number of atoms of Na with the Avogadro's Number.

1.806x10²⁴ atoms Na x 1 mole Na / 6.022x10²³ atoms Na

= 2.99 or 3 moles Na
