Liquid gasoline is heated and becomes gasoline vapor. The gasoline vapor is then ignited by a spark, causing a fire. The entire process is: Group of answer choices

First an endothermic and then followed by the exothermic process

Explanation:

Based on the information given in the question, we should note that the entire process is an endothermic process at first and then an exothermic process.

We should note that heat is absorbed during an endothermic process and the environment is cooled but for an exothermic process, heat is being released which leads to the increase in the temperature of the surroundings.

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.
