NO 2 + O 3 → NO 3 + O 2. During the daytime, NO 3 is quickly photolyzed back to NO 2, but at night it can react with a second NO 2 to form dinitrogen pentoxide. NO 2 + NO 3 (+M) → N 2 O 5 (+M). N 2 O 5 reacts rapidly with liquid water (in aerosol particles or cloud drops, but not in the gas phase) to form HNO 3, N 2 O 5 + H 2 O (liq) → 2 ...

It is often given as its base-10 cologarithm, p K a. acid–base extraction A chemical reaction in which chemical species are separated from other acids and bases. acid ...
The rate of mass flow per unit area. The common symbols are j, J, φ, or Φ, sometimes with subscript m to indicate mass is the flowing quantity. Its SI units are kg s−1 m−2. mass moment of inertia A property of a distribution of mass in space that measures its resistance to rotational acceleration about an axis. mass number
In linguistics, a blend—also known as a blend word, lexical blend, or portmanteau [a] —is a word formed by combining the meanings, and parts of the sounds, of two or more words together.
