Answer:

The correct answer will be option-gravitational energy.

Explanation:

The gravitational force is the attractive force which exists between two objects with mass. This attractive force directly influence the other object as it helps maintain the object in the universe.

When one of the objects out of two is earth, the force is termed as gravity or it is the force with which the earth attracts the object.

The gravity is directly proportional to mass due to which the earth will attract the object with stronger force. When the object will be present at the height the strongest force applied on the object will be the gravitational force.

Thus, gravitational energy is the correct answer.

Is glue a liquid or a solid
Cerrena [4.2K]

Answer:

White school glue is liquid because its long polymers can slide over and along one another. It does not flow easily, though; it is quite viscous. The addition of some chemicals—such as a borax solution (or sodium tetraborate decahydrate dissolved in water)—can cause cross-links to form between the polymers.

At elevated temperature, carbon tetrachloride decomposes to its elements: CCl4(g) C(s) 2Cl2(g). At 700 K, if the initial pressur
PIT_PIT [208]

Answer:

K=0.0131M

Explanation:

Hello,

In this case, the undergoing chemical reaction turns out:

CCl_4(g) \rightleftharpoons C(s)+ 2Cl_2(g)

In such a way, by means of the mass of law action for such reaction, which is given below:

Kp=\frac{p_{Cl_2}^2}{p_{CCl_4}}

And in terms of the change x due to reaction extent:

p_{CCl_4}=p_{CCl_4}^0-x\\p_{Cl_2}=2x\\p_T=p_{CCl_4}+p_{Cl_2}=1.00-x+2x\\p_T=1.00+x

x results:

x=1.35 atm -1.00atm=0.35atm

In such a way, Kp:

Kp=\frac{(2x)^2}{1.00-x} =\frac{(2*0.35atm)^2}{1.00atm-0.35atm}=0.754atm

Nonetheless, K is asked instead of Kp, thus:

K=\frac{Kp}{(RT)^{\Delta \nu _{gas}}}

Whereas:

\Delta \nu _{gas}=2-1=1

Which is the change in the moles of gaseous species chlorine and carbon tetrachloride. Hence, we finally obtain:

K=\frac{0.754atm}{(0.082\frac{atm*L}{mol*K}*700K)^{1}}\\\\K=0.0131mol/L=0.0131M

Best regards.
