Water has a specific heat of 4.186 J/gºC, and ethanol has a specific heat of 2.450 J/g °C. Based on this
information, which best compares water and ethanol?
Ethanol has a lower molar mass.
Water has more protons and neutrons in its nuclei.
It requires less heat to raise the temperature of a gram of ethanol by 1°C.
There are less molecules in a gram of water.

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.

because natural gas is colorless, odorless, and tasteless, distributors add mercaptan (a chemical that smells like sulfur) to give natural gas a distinct unpleasant odor (it smells like rotten eggs). they locate the types of rock that are likely to contain natural gas deposits.
