6,000 m . (or, write as: 6,000 meters).
_______________________________________________________
Explanation:
_________________________________________________
Note the exact conversion: 1 km = 1000 m .
______________________________________________________
Note: "km" is an abbreviated form of "kilometer(s)".
"m" is an abbreviated form of "meter(s)".
______________________________________________________
Here is one way to solve, using a method called "dimensional analysis":
_______________________________________________________
Given: 6 km ; convert to "m" ;
______________________________________________________
→ 6 km =    ?    m ;
___________________________________________________
  → 6 km * $\frac{1000 m}{1 km}$ = ?    m ;
___________________________________________________
→ On the "left-hand side" of the equation, the units of "km" "cancel out" to "1" ; and we are left with:
_______________________________________________
→ 6 * $\frac{1000 m}{1$ =    ? m ;
_______________________________________________
.→ 6 * 1000 m =   ?   m  ;
_______________________________________________
→ = 6,000 m ; or write as: 6,000 meters .

Answer from: Quest

answer: option (b) is the correct answer.

explanation:

a covalent bond is formed by sharing of electrons. whereas polarity arises due to difference in electronegativity of two atoms.

therefore, more is the electronegativity of an atom which combines with the titanium, more readily it will induce a partial positive and negative charge.

thus, out of the given options fluorine is most electronegative and has an incomplete octet. therefore, it will readily combine with titanium to share the electrons and complete its octet.

Answer from: Quest

Spontaneity tell us the direction of the reaction, but not how fast it goes. gibbs free energy brings together enthalpy, entropy and temperature in one easy formula. g = h - ts. and, finally the sign of delta g is always negative for a spontaneous reaction.
