Answer:
C. 1.35
Explanation:
2NH3 (g) <--> N2 (g) + 3H2 (g)
Initial concentration 2.2 mol/0.95L 1.1 mol/0.95L 0
change in concentration 2x x 3x
-0.84 M +0.42M +1.26M
Equilibrium 1.4 mol/0.95L=1.47M 1.58 M 1.26 M
concentration
Change in concentration(NH3) = (2.2-1.4)mol/0.95 L = 0.84M
Equilibrium concentration (N2) = 1.1/0.95 +0.42=1.58 M
Equilibrium concentration(NH3) = 1.4/0.95 = 1.47M
K = [N2]*{H2]/[NH3] = 1.58M*1.26M/1.47M = 1.35 M
It is true, here is evidence to this question "<u>People are heterotrophs</u>: we eat plants or meat to stay alive. You might say, well, isn't everything a heterotroph? A lot of creatures are, including giraffes, dogs, fish, <em>horses </em>" I hope this helps you with what your doing.
Answer:
this option is correct the amount of heat required to turn a mole of a solid into a liquid
Answer:
B. 6.3 × 10² J
Explanation:
The formula for work (w) done is
w = f×d
f = 70 N
d = 10 m
w = 70 × 10
w = 700 J = 7 × 10² J
w is <em>positive</em> because work is being done on the object.
