Shee t Version 2.0 | March 2021 1 FORMALDEHYDE Other Names Formalin, Methanal, Oxymethylene, Methylaldehyde, Oxomethane, Methyl aldehyde, Methylene glycol, Methylene oxide, Formol, Carbonyl hydr There are two basic questions for a chemical reaction –. (. i. ) How . far the reaction proceeds?. . and. (ii) How . fast does it proceed?. # Answer to the . question . Scientific opportunities with . als. -U. 1. Damage-free probing of aerosol reactions with <1 . m. s time resolution. Probe with soft x-ray . nanoprobes. , full-field soft x-ray microscopy. Aerosols are submicron compartmentalized chemical reactors. Chemical kinetics is concerned with the rate and mechanism of chemical change. . Homogeneous reaction:- . A reaction which occurs entirely in one phase.. Heterogeneous reaction:- . A reaction which occurs two or more phases..
