A144.7 g piece of metal has a density of 7.57 g/ml. a 100 ml graduated cylinder contains 25.9 ml of water. what is the final volume after the metal is added to the graduated cylinder?

Explanation:

Hello,

In this case, we firstly must compute the volume of the piece of metal by using its density as shown below:

Then, by adding the initial volume of water and the volume of the metal, one obtains the final volume:

Best regards.

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.
