Willowbrook: The Last Great Disgrace 1. What are the living conditions of the children and adults that are staying in this mental
institution?
2. During the day time, are the children and teens given any educational programs? If not,
what are they left to do all day?
3. How long does the staff have to feed each child that cannot feed themselves? How
much time should the staff be taking to feed each child?

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.  

the density of gold = 19.3 g/cm3

the relation between density and mass and volume is

density = mass / volume

given :

mass of gold = 13 g

density = 13g / volume = 19.3

volume = 13 /19.3 = 0.67 cm^3

thus volume of gold nugget = 0.67 cm^3
