You aren't asking anything I don't know how to this. But if you're wondering, potassium does react (explode) to cold water and air, because it's an alkali metal (a element on the very right group or column of the Periodic Table). All alkali metals really want to lose an electron, making them highly reactive, and the further down the alkali metals you go, the more reactive they are.
They go boom when they come in contact with each other.
A violent chemical reaction:
2 K + 2 H2O = 2 KOH + H2
A violent reaction: hydrogen and potassium hydroxide results from this reaction.
a. a single-displacement reaction b. a double-displacement reaction c. a decomposition reaction d. electrolysis
2K + 2H20 -> 2KOH + H2
endothermic reaction.
it fizzles and swims around for a bit but then lights up like a sparkler its really cool
Down a group, the ionisation energy decreases, electropositivity increases. Hence potassium is more reactive than sodium.
Don't know about pattasium.
But potassium does. Like the other alkali metals, potassium reacts violently with water, producing hydrogen.
The explosive force is the reaction of potassium with water liberating hydrogen.
if the water is cold then the crystal will take time to dissolve as particles move slowly when in cold water. therefore, after 5 minutes it will still be the same or if its normal water it will start to diffuse slowly.
They react pretty violently with water. These elements have 1 valence electron with makes them very reactive. When they are put in the water they split the water molecule into Hydrogen gas and NaOH or LiOH, etc. Lithium, sodium and potassium while violent reactions are pretty mellow compared to the reactions of Rubidium, Cesium and Francium. Search google video for cesium reaction with water and you will see what i mean.
It drops in temperature. It gets cold.
The product of the reaction between cyclohexene and hot acidified potassium manganate 7 will be cyclohexan-1,2-diol. Two hydroxy groups will bond at the site of the double bond.
The explosive force is the reaction of potassium with water liberating hydrogen.
Potassium metal is a metal that explodes when put in cold water. It causes a chemical reaction which results in a large explosion.
Rubidium, caesium and francium. Potassium will generate enough heat to ignite the hydrogen produced in the reaction but the reaction is not really explosive.
You get a mixture of potassium and magnesium. They're metals; they don't react with each other.
Potassium Manganate (VII) also called potassium permanganate, dissolves very quickly in hot water and much slower in cold water.
A reaction with water (hot or cold) is a chemical reaction.
potassium hydroxide
One would expect that the reaction between an alkene and cold, dilute potassium dichromate is an oxidation to a bifunctional alcohol at the carbons in the double bond. The result is also called a vincinal diol or a glycol. The reaction should be similar to the reaction of an alkene with cold, dilute potassium permangante, however, dichromate is a milder oxidizing agent and may not be as effective. The mechanism for this reaction involves the formation of an intermediete 'ester' with the metal at the carbons of the double bond, breaking the double bond. The it can be shown that the resonance structure of the intermediete complex transfers electron density to the ester linkage and protonates from water at both of the ester sites completing the oxidation.
A violent reaction occur and hydrogen is released.
if the water is cold then the crystal will take time to dissolve as particles move slowly when in cold water. therefore, after 5 minutes it will still be the same or if its normal water it will start to diffuse slowly.
Cobalt does not react with cold water. With extreme heat, CoO can form.
Heating is a chemical phenomenon.
