B. the uncertainty is in the hundredth place.
C. the uncertainty is in the ones place.
D. a mass measured on this balance will always have 4 significant digits.
E. the uncertainty is in the tenths place.
F. the mass measured on this balance is known exactly.
G. a mass that falls between 1 gram and 9 grams measured on this balance will always have 3 significant figures.
H. a mass that falls between 10 grams and 80 grams measured on this balance will always have 3 significant figures.
I. a mass that falls between 100 and 200 grams measured on this balance will have 5 significant figures.

1.72 moles of NOCI were placed in a 2.50 L reaction chamber
elena-14-01-66 [18.8K]

The equilibrium constant, Kc=0.026

<h3>Further explanation</h3>

Given

1.72 moles of NOCI

1.16 moles of NOCI  remained

2.50 L reaction chamber

Reaction

2NOCI(g) = 2NO(g) + Cl2(g).

Required

the equilibrium constant, Kc

Solution

ICE method

   2NOCI(g) = 2NO(g) + Cl2(g).

I    1.72

C   0.56           0.56         0.28

E   1.16              0.56         0.28

Molarity at equilibrium :

NOCl :

\tt \dfrac{1.16}{2.5}=0.464

NO :

\tt \dfrac{0.56}{2.5}=0.224

Cl2 :

\tt \dfrac{0.28}{2.5}=0.112

\tt Kc=\dfrac{[NO]^2[Cl_2]}{[NOCl]^2}\\\\Kc=\dfrac{0.224^2\times 0.112}{0.464^2}=0.026
