What types of changes occur during the erosion and deposition of sediments in a river? A The erosion and deposition of sediment are physical changes.
B The erosion and deposition of sediment are chemical changes.
C The erosion of sediment is a chemical change, and the deposition of sediment is a physical change.
D The erosion of sediment is a physical change, and the deposition of sediment is a chemical change.

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.

1.43 x 10^-11 j the guy commented the awnser just making sure u see it .

hey there!

mass = 6.75 g

volume =   9 cm³

therefore:

d = mass / volume

d   = 6.75 / 9

d = 0.7 g/cm³

answer b
