The minimum amount of unstable atoms needed to produce an uncontrolled chain reaction is called . atomic mass
mass number
critical mass

The most efficient way to establish the best possible economizer position is to measure

If a reactant was removed, did the new equilibrium system shift to make more reactants or more products?

Phosphorous acid, h3po3(aq) , is a diprotic oxyacid that is an important compound in industry and agriculture. p k a1 p k a2 1.30 6.70 calculate the ph for each of the points in the titration of 50.0 ml of 1.5 m h3po3(aq) 1.5 m h 3 po 3 ( aq ) with 1.5 m koh(aq). 1.5 m koh ( aq ) .
