According to the law of conservation of energy, a) an object loses most of its energy as friction. eliminate b) the total amount of energy for a system stays the same. c) the potential energy of an object is always greater than its kinetic energy. d) the kinetic energy of an object is always greater than its potential energy

B

Explanation:

This is what the law of conservation of energy is.

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.  

it is the most commonly accepted one
