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.

An unknown substance has been shown to have weak covalent bonds.
Anton [14]

Answer:

Low melting point.

Explanation:

We cannot link the pH of a substance from it bonds directly.

Ionic compounds have strong ionic bonds but we cannot say that they will have high or low pH.

High conductivity is a feature of ionic compounds generally (also metals)

low melting point means the bonds are weak so they can be weak covalent bonds.

Low flammability is not related to bonding.

1.Explain the difference between a FIXED VOLUME and an ELASTIC VOLUME
In-s [12.5K]

Answer:

Fixed volume is the property of liquid and solid which means that the volume of both solid and liquid remain fixed or constant under fixed temperature and pressure.

Elastic Volumes makes it easy to dynamically increase capacity, tune performance, and change the type of any new or existing current generation volume with no downtime or performance impact.
