Given 1 in=2.54 cm, how many centimeters are in an average hand (9.50 inches) __ cm (3 significant figures)

9.5 inches = 24.1 cm

Explanation:

Given that,

1 inch = 2.54 cm

We need covert 9.5 inches to cm. For this we will use unitary method. To convert 9.5 inches to cm multiply 2.54 and 9.5. So,

9.5 inches = (2.54 × 9.5) cm

9.5 inches = 24.13 cm  

or

9.5 inches = 24.1 cm

Hence, this is the required solution.

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.
