Is the reaction between potassium permanganate and glycerin a endothermic or exothermic reaction?
Exothermic
Is Potassium nitrate endothermic or exothermic?
The dissolution of potassium nitrate in water is an endothermic process.
Can potassium dissolve in water?
Yes. potassium will dissolve in water forming potassium hydroxide and hydrogen gas. however, the reaction is very exothermic and will generally catch fire.
What type of reaction does potassium chloride have?
The compound contains the two elements Potassium and chlorine it is an exothermic chemical reaction because it releases heat energy when formed.
What flame does potassium give?
Potassium itself is not flammable. However, if in contact with water, it exothermic reaction releases flammable hydrogen which can burn violently.
Is the reaction of potassium carbonate with dilute HCl exothermic or endothermic?
It is an exothermic reaction.
Is the reaction between potassium permanganate and glycerin a endothermic or exothermic reaction?
Exothermic
Is Potassium nitrate endothermic or exothermic?
The dissolution of potassium nitrate in water is an endothermic process.
Can potassium dissolve in water?
Yes. potassium will dissolve in water forming potassium hydroxide and hydrogen gas. however, the reaction is very exothermic and will generally catch fire.
What is the reaction between hydrochloric acid and potassium metal?
There will be an strong exothermic reaction which will flame and sputter.
Why is the lattice energy of potassium bromide more exothermic than the lattice energy of rubidium iodide?
The lattice energy of potassium bromide is more exothermic than the lattice energy of rubidium iodide because lattice energy is inversely proportional to atomic radius.
Is an endergonic reaction spontaneous or not?
No, an Endergonic Reaction is not spontaneous because it requires a minimal amount of energy to get the reaction to actually start. That amount of energy required to start the reaction is called the Activation Energy.
Is reaction of potassium iodide and water exothermic or endothermic?
Its endothermic... In my experiment, it went from 26 to 25 degrees celsius... Its endothermic... In my experiment, it went from 26 to 25 degrees celsius... This is wrong it is exothermic. Potassium chloride is snow salt. it is used because not only does it react with the snow to create hydrochloric acide and potassium hydroxide (both with much lower freezing points) but, the EXOTHERMIC reaction also helps melt the snow No, it is endothermic. The only reason we add salt to snow is to lower the melting point. If you're curious, dissolve as much KCl in a beaker as you can as quickly as you can. The water temperature will drop dramatically.
What happens to the solubility of potassium nitrate as the temperature rises?
The solubility of potassium nitrate increase with the temperature.
What type of reaction does potassium chloride have?
The compound contains the two elements Potassium and chlorine it is an exothermic chemical reaction because it releases heat energy when formed.
What is potassium at room tempiture?
Potassium at room temperature is a solid.
What flame does potassium give?
Potassium itself is not flammable. However, if in contact with water, it exothermic reaction releases flammable hydrogen which can burn violently.
