A sample of pure NH4HS is placed in a sealed 2.0-L container and heated to 550 K at which the equilibrium constant is 3.5 x 10-3

Zolol [24]

Answer:

The mass of $NH_{3}$ in the container is 2.074 gram

Explanation:

Given:

Volume of $NH_{4} HS$ $V = 2$ lit

Equilibrium constant $k _{eq} = 3.5 \times 10^{-3}$

The reaction in which $NH_{3}$ is produced

$NH_{4} HS$ ⇄ $NH_{3} + H_{2}S$

Here equal moles of $NH_{3}$ and $H_{2}S$ is formed.

From the formula of equilibrium constant,

$k_{eq} = (NH_{3})(H_{2}S )$

$x^{2} = 3.5 \times 10^{-3}$

$x = 0.061$ M

Above value shows,

$NH_{3} = 0.061$ $\frac{moles}{L}$

So in 2 L no. moles of $NH_{3}$ = $0.061 \times 2 = 0.122$ moles.

So mass of 0.122 mole of $NH_{3}$ is = $0.122 \times 17 = 2.074$ g

Therefore, the mass of $NH_{3}$ in the container is 2.074 gram

Please HELP!

abruzzese [7]

This would be difficult to specify for you because you did not provide the genotype of the other parent. However, there are limitations to the possible combinations, so I will do each to help you out.

1st possibility:

B B

B BB BB

b Bb Bb

Brown eyes: 4 out of 4 or 100%

Blue eyes: 0 out of 4 or 0%.

2nd possibility:

B b

B BB Bb

b Bb bb

Brown eyes: 3 out of 4 or 75%

Blue eyes: 1 out of 4 or 25%.

3rd possibility:

b b

B Bb Bb

b bb bb

Brown eyes: 2 out of 4 or 50%

Blue eyes: 2 out of 4 or 50%.

As long as there is a capital letter in the genotype, the dominant trait will come out. So if the combination is Bb or BB, then BROWN in this case will come out. The only time BLUE eyes will come out is if has two recessives in its genotype or bb.
