Potassium Manganate (VII) also called potassium permanganate, dissolves very quickly in hot water and much slower in cold water.
because the boiling and freezing points can be from two different substances so one could be frozen at 0 degrees and the other boiling
The atomic mass of Potassium is 39 and that of Sulfur 32. The formula for Potassium Sulfide is K2S therefore the molecular weight of Potassium Sulfide is (39 * 2) + 32 = 110. Therefore one mole of Potassium Sulfide weighs 110 grams. Therefore 3.3 moles of Potassium Sulfide weigh 110 * 3.3 = 363 grams.
an electric steamer is a 1-3 storie applience which you can buy from any shop and will steam your food instead of you boiling it in a souce pan
Because of the relation between the two scales: [°F] = [°C] × 9⁄5 + 32
As the heat content increases, the temperature of the substance will rise. However, if the substance is not at its melting or boiling point, it will not undergo a phase change. Instead, its temperature will continue to increase until it reaches its melting or boiling point, at which point a phase change will occur.
Potassium Dichromate (VI) can be acidified with sulphuric acid AND hydrochloric acid! Note that another common oxidising agent ' Acidified Potassium Manganate (VII)' is sometimes used although this one can only be acidified with sulphuric acid not hydrochloric as the Manganate (VII) oxodises the Cl- ion instead!
yes probs as bananas do have potassium in
Potassium chloride is melted at 770 oC.
potassium chloride
the potassium trioxalatomanganateIII contains manganese (III) in thee complex, whereas the trioxoaluminate contains aluminum in the complex instead
What?!
That's like boiling but in oil instead of water.
You can make hot cinnamon toothpicks using boiling water instead of soaking in a jar by using regulated heat.
If you mean can potassium chloride be used instead of table salt, then yes, though they probably won't taste as good.
Yes, because chemical properties of sodium and potassium ions are nearly same.
It's K because the Latin word for potassium is "Kalium". And the symbol P belongs to phosphor.
Potassium hydroxide is the compound potassium hydroxide but as it is quite hygroscopic the "dry form" also contains a significant amount of the compound water that it extracted from the surrounding air. If instead you were asking about its elements, they are: potassium, oxygen, and hydrogen.
