For the reaction A + B → products, it is observed that
(a) On doubling the initial concentrations of both A
and B, the rate of reaction becomes four times
(b) On doubling the initial concentration of B only, the
rate of reaction is also doubled
The expression for this reaction rate is given by​

the number of valence electrons for each molecule or ion is shown beneath the structure. remember hydrogen will not have more than two electrons. this hydrogen is part of a covalent bond (sharing two electrons). a double bond here would cause hydrogen to share four electrons with phosphorus.

metric time was an attempt to create a standard unit of time based off of 10, but it never took off an is not included in the metric system (si)
