Which sentence correctly compares the acidity of acid rain to the acidity of natural rainwater? a. the acidity of acid rain is more basic than the acidity of natural rainwater. b. the acidity of acid rain is less than the acidity of natural rainwater. c. the acidity of acid rain is greater than the acidity of natural rainwater. d. the acidity of acid rain is the same as the acidity of natural rainwater.

C. The acidity of acid rain is greater than the acidity of natural rainwater.

Explanation: Acid rain is caused by the oxides of sulfur and nitrogen which when react with water lead to formation of acids and when combines with rain is called as acid rain.

pH is the measure of acidity or alkalinity. More is the amount of ions, lesser is the pH and more is the acidity.

the answer to your question is:

c. complementary base-pairing

water is a polar molecule. a chemical bond is a force of attraction between atoms or ions. bonds form when atoms share or transfer valence electrons. atoms form chemical bonds to achieve a full outer energy level, which is the most stable arrangement of electrons. so, false

explanation:

in h2o molecule, two water molecules are bonded by a hydrogen bond but the bond between two h - o bonds within a water molecule are covalent. the greater the electronegativity difference, the more ionic the bond is. bonds that are partly ionic are called polar covalent bonds. nonpolar covalent bonds, with equal sharing of the bond electrons, arise when the electronegativities of the two atoms are equal.
