Areaction has initial concentration of 0.230 m fe3+ and 0.410 m scn- at equilibrium, the concentration of fescn2+ is 0.150 m. a. what is the concentration of the fe3+ at equilibrium? b. what is the concentration of the scn- at equilibrium?

Answer :

a) The concentration of at equilibrium is 0.08 m.

b) The concentration of at equilibrium is 0.26 m.

Solution :

The equilibrium reaction is,

Initial concentration          0.230         0.410          0

At equilibrium              (0.230 - x)    (0.410 - x)       x

Given x = 0.150

Therefore,

The concentration of = 0.230 - x = 0.230 - 0.150 = 0.08

The concentration of = 0.410 - x = 0.410 - 0.150 = 0.26

Thus, the concentration of at equilibrium is 0.08 m.

The concentration of at equilibrium is 0.26 m.

because natural gas is colorless, odorless, and tasteless, distributors add mercaptan (a chemical that smells like sulfur) to give natural gas a distinct unpleasant odor (it smells like rotten eggs). they locate the types of rock that are likely to contain natural gas deposits.

weight of any object is given by

w = m*g

where m is mass of the object and g is the acceleration due to gravity.

for earth the value of g is 9.8 m/s^2 so

w=117.6 n m=12 g=?

117.6=12g => g=9.8 m/s^2

which is the force of gravity on earth.
