Thisresults in a permanent dipole, leaving a partial positive charge on the hydrogens. The extra electron density on the oxygen leavesa partial negative charge. Therefore, water is a polar molecule and has the ability to form hydrogen bonds. These propertiesexplain many of water's characteristics, including why ice is less dense than liquid water.Sort the following images into phases of water.Drag and drop options on the right-hand side and submit.

Benzene is a carbohydrate ubiquitous to organic chemistry. Its structure was proposed near the end of the 1800s by the, German chemist Kekul'e after he supposedly dreamt of a snake devouring its own tail. Knowing that benzene has a percent composition of 92.24% carbon and 7.76% hydrogen by mass and a molar mass of 78.11 g/mol, determine the compound's molecular formulas. Please provide your answer as the value of n.
(b) Explain each of the following in terms of the properties of water.

Atoms A and B interact to form a compound, AB2. When measured, atom A has a partial negative charge and atom B has a partial positive charge. From this information, we can conclude what?

Discuss whether the following statement is correct: “An ionic bond can, in principle, be thought of as a very polar covalent bond. Polar covalent bonds, then, fall somewhere between ionic bonds at one end of the spectrum and nonpolar covalent bonds at the other end.”
