Answer:
B). Electrons are more attracted to the oxygen atom, so there is a partial negative charge on the oxygen atom.
Explanation:
The above statement most aptly describes the polarity or uneven distribution of the density of electrons. In water, two hydrogen atoms and one atom of oxygen leading to the formation of polar covalent bonds. Thus, <u>there is the presence of a partial negative charge close to the oxygen atom and partial positive charge near the hydrogen atom as the former has unshared pair of electrons</u>. This polarity of water allows it to dissolve sugar or other ionic substances in it. Thus, <u>option B</u> is the correct answer.

When the concentration is expressed in mass percentage, that means there is 3 g of solvent H₂O₂ in 100 grams of the solution. Then, that means the remaining amount of solute is 97 g. We use the value of molarity (moles/liters) to determine the amount of solution in liters, denoted as V. The solution is as follows:
0.02 mol KMnO4/L solution * 158.034 g KMnO4/mol * V = 97 g KMnO4
Solving for V,
V = 30.69 L
