Carbon tetrachloride has been widely used in the cleaning industry, in fire extinguishers, and as a refrigerant. Construct an ex

planation of how carbon and chlorine combine to form carbon tetrachloride. A) Nonmetal carbon shares valence electrons with each nonmetal chlorine forming four covalent bonds. B) Nonmetal carbon loses a valence electron and chlorine metal gains a valence electron to form an ionic bond. C) Carbon and chlorine are nonmetals and they shares their valence electrons to become ions and form ionic bonds. D) Chlorine metal loses a valence electron to become a cation and nonmetal carbon gains a valence electron to become an anion forming a covalent bond.

Answer: A) Nonmetal carbon shares valence electrons with each nonmetal chlorine forming four covalent bonds.

Explanation: Covalent bond is formed by sharing of electrons between atoms.

Ionic bond is formed by transfer of electrons between atoms.

Carbon with atomic no 6 and has configuration of 1s^22s^22p^2. Carbon has 4 valence electrons. It can only share electrons as it is difficult to gain or lose 4 electrons to complete it's octet.

Chlorine with atomic no 17 has configuration of 1s^22s^22p^3s^23p^5. It has 7 valence electrons and need one electron to complete its octet.

Thus carbon will share 4 electrons, one each with four chlorine atoms to form carbon tetra chloride.

Complete Question

Questions Diagram is attached below

Answer:

*  W=1142.86Joule

*  Q=997.7J

*  H=2140.5J

Explanation:

From the question we are told that:

Temperature T=337K

Pressure P=(60-55)Pa*10^5

VolumeV=(1.6-1.4)m^3*10^{-3}

Generally the equation for gas Constant is mathematically given by

\frac{P_2}{P_1}=\frac{V_1}{V_2}^n

 \frac{55*10^5}{60*10^5}=\frac{1.4*10^{-3}}{1.6*10^{-3}}^n

 n=0.65

Therefore

Work-done

 W=\int{pdv}

 W=\frac{55*10^5*1.6*10^{-3}*60*10^5*1.4*10^{-3}}{1-0.65}

 W=1142.86Joule

Generally the equation for internal energy is mathematically given by

 Q=mC_vdT\\\\Q=\frac{3*1*3.314*16}{1.4-1}

 Q=997.7J

Therefore

 H=Q+W

 H=997.7J-11.42.9

 H=2140.5J

Identify each of the following solids as molecular, ionic, or atomic.
Kisachek [45]

Answer :

(A) Br₂ (s) : molecular solids

(B) AgCl (s) : ionic solids

(C) S (s) : atomic solids

(D) CH₄ (s) : molecular solids

Explanation :

Molecular solids : It is defined as the solids in which they are held together by covalent forces, dipole interactions as attractive forces etc.

Ionic solids : It is defined as the solids in which the atoms composed with oppositely charged ions.

Atomic solids : It is defined as the solids in which the molecules are held together by covalent forces and also includes pure substance.

(A) Br₂ (s)

It is molecular solids because they are held together by covalent forces.

(B) AgCl (s)

It is ionic solids because in this atoms composed with oppositely charged ions.

(C) S (s)

It is atomic solids because it is a pure substance.

(D) CH₄ (s)

It is molecular solids because they are held together by covalent forces.

Explain, in terms of particles, why liquid<br> iodine does not conduct electricity.
drek231 [11]

Answer:

Because iodine is a liquid, it has no melting point. Iodine is not an electrical conductor because each molecule consists of two iodine atoms connected by a covalent bond that cannot be stimulated sufficiently to transmit electrical energy.
