Consider the reaction. Upper n subscript 2 (g) plus 3 upper H subscript 2 (g) double-headed arrow 2 upper N upper H subscript 3
umka2103 [35]

The equilibrium constant of the reaction is 0.0030.

The equation of the reaction is given as;

N2(g) + 3H2(g) ⇆ 2NH3 (g)

We have the following information at equilibrium;

[NH3] = 0.105 M

[N2] = 1.1 M

[H2] = 1.50 M

Hence, we can calculate the equilibrium constant using the relation;

K = [NH3]^2/ [N2]  [H2]^3

Substituting values;

K = [0.105]^2/[ 1.1] [1.50]^3

K =0.011025 /3.7125

K= 0.0030

A sample of a radioactive isotope had an initial mass of 480 mg in the year 2009 and decays exponentially over time. A measureme
r-ruslan [8.4K]

Answer:

1445 mg

Step-by-step explanation:

If you go from 2009 to 2011 and decayed 390 mg, you divide that by two to see how much it decays in one year. After you get that, you multiple 195 by 5 and get 975. your initial value is 480, so you would add 975 and 480 to get the answer 1445 mg. I am only in the 7th grade, so I could be wrong but it looks like a simple slope problem and I feel pretty confident about my answer.
