Which of the following is the term for the heaviness on something's surface that exerts a force over an area
yarga [219]

Answer:

A

Explanation:

I think it's pressure. Using the process of elimination,  sediment is the matter that's on the bottom of a liquid or solution, deposition is the process of deposing, eruption is the process of erupting, and pressure's formula is force/area, so pressure is the answer.

In methane combustion, the following reaction pair is important: At 1500 K, the equilibrium constant Kp has a value of 0.003691
andre [41]

Explanation:

Let us assume that the value of K_{r} = 2.82 \times 10^{5} \times e^({\frac{-9835}{T}}) m^{6}/mol^{2}s

Also at 1500 K, K_{r} = 2.82 \times 10^{5} \times e^({\frac{-9835}{1500}}) m^{6}/mol^{2}s

                     K_{r} = 400.613 m^{6}/mol^{2}s

Relation between K_{p} and K_{c} is as follows.

                  K_{p} = K_{c}RT

Putting the given values into the above formula as follows.

                  K_{p} = K_{c}RT

         0.003691 = K_{c} \times 8.314 \times 1500

                K_{c} = 2.9 \times 10^{-7}

Also,     K_{c} = \frac{K_{f}}{K_{r}}

or,                K_{f} = K_{c} \times K_{r}

                               = 2.9 \times 10^{-7} \times 400.613

                               = 1.1617 \times 10^{-4} m^{6}/mol^{2}s

Thus, we can conclude that the value of K_{f} is 1.1617 \times 10^{-4} m^{6}/mol^{2}s.

Sulfuric acid (H2SO4) and Ba(OH)2 solutions are strong electrolytes and give a bright glow on the light bulb of your conductivit
scoray [572]

Answer:

See Explanation

Explanation:

An electrolyte is a solution which is able to conduct electricity. An electrolyte conducts electricity because of the presence of ions which move around in the solution.

Ba(OH)2 and H2SO4 are composed of ions; these ions are the charge carriers in solution and are responsible for the conductivity of the solution and the glow of the bulb.

When Ba(OH)2 and H2SO4 are mixed, the following reaction occurs;

Ba(OH)2(aq) + H2SO4(aq) -------->BaSO4(s) + 2H2O(l)

The formation of the BaSO4(s) precipitate removes the ions that are responsible for the conductivity of the solution hence the  light bulb of the conductivity apparatus dims and eventually fades completely.
