Question
Potassium (K) metal, when reacted with
water, yields potassium hydroxide (KOH) and
hydrogen gas (reaction is shown below). This
is an exothermic reaction in which the heat
released is enough to cause the hydrogen
gas to ignite and the aqueous KOH to plaster.
If accidentally, 8.56 mol K were put in water,
how many grams of KOH will possibly
plaster? (MM KOH= 56 g/mol) *
2 К + 2 H2О > 2 КОН + Н2
