Answer:

Explanation:

Muscles in a kangaroo’s legs work because of the cells that make up the muscle. Which component of cell theory does this best illustrate?

All living things are made of cells.

Cells are the basic unit of structure and function of all living things.

All cells come from other cells.

Cells are generated from nonliving materials.

Cells are the basic unit of structure and function of all living things.

At a high temperature, equal concentrations of 0.160 mol/L of H2(g) and I2(g) are initially present in a flask. The H2 and I2 re
Nikitich [7]

Explanation:

The given reaction is as follows.

                                H_{2} + I_{2} \rightarrow 2HI

Initial :                  0.160    0.160          0  

Change :                  -x           -x              2x

Equilibrium:        0.160 - x    0.160 - x       x

It is given that [H_{2}] = [0.160 - x] = 0.036 M

and,                [I_{2}] = [0.160 - x] = 0.036 M      

so,                             x = (0.160 - 0.036) M

                                    = 0.124 M

As, [HI] = 2x.

So,           [HI] = 2 \times 0.124

                       = 0.248 M

As it is known that expression for equilibrium constant is as follows.

               K_{eq} = \frac{[HI]^{2}}{[H_{2}][I_{2}]}

                                  = \frac{(0.248)^{2}}{(0.036)(0.036)}

                                  = 47.46

Thus, we can conclude that the equilibrium constant, Kc, for the given reaction is 47.46.
