Carbon tetrachloride (ccl4) is ionic or convalent

Covalent.

Explanation:

In carbon tetrachloride, chlorine and carbon are bounded with each other by single covalent bond. Carbon atom contains eight electrons in outer shell and chlorine atom also have eight electrons, so they are completing their octet by the sharing of electrons with each other.

Covalent bond is forming by the overlap of orbital, in CCl4 overlap is occurred so it is a covalent bounded compound. Formation of Ionic compounds occurs when two opposite charged ions interact with each other by electrostatic interaction such as NaCl, Na having positive and Cl having negative charge.

So, the answer is covalent bond.

d₁ = displacement of tern from arctic to antarctic = 11000 miles

d₂ = displacement of tern from antarctic to arctic =   - 11000 miles

d = total displacement for the journey

total displacement for the journey is given as

d = d₁ + d₂

d = 11000 + (-11000)

d = 0 miles

t₁ = time of travel from arctic to antarctic = 3 months = 3 x 30 days = 90 days

t₂ = time of travel from antarctic to arctic = 3 months = 3 x 30 days = 90 days

t = total time of travel

total time of travel is given as

t = t₁ + t₂

t = 90 + 90

t = 180 days

average velocity is given as

average velocity = total displacement/ total time

v = d/t

v = 0/180

v = 0 miles/day
