Match the following.
1. the temperature on the kelvin scale at which entropy occurs

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.  

space exploration has led to the development and technological improvement of many everyday items. (if this answer is wrong i will find the right answer) : )

c. orbital shape i hope this is correct
