In a reaction, 224 g of iron (Fe) are available that react completely with 96 g of oxygen gas (O2) to form iron trioxide
(Fe2O3). If 190 g of iron is available: a) how many grams of oxygen are
necessary. b) How many grams of iron trioxide are formed?​

Atomicity occurs to prevent updates of the database occurring only partially, which can cause greater problems than rejecting the whole series outright.some are monatomic, diatomic, triatomic etc because it shows the number of atoms. for example, monatomic means it contains only one atom.

Rate law for this reaction israte of the reaction = k[a]²[b].second order in a  means concentration of a in power of two, and  first order in b means concentration of b in power of one.
