How can the boiling point of water be raised or lowered?
because the boiling and freezing points can be from two different substances so one could be frozen at 0 degrees and the other boiling
How many grams are there in 3.3 moles of potassium sulfide?
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.
What is an electric steamer?
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
Why is the boiling point of water 212 degrees on a Fahrenheit scale instead of 100?
Because of the relation between the two scales: [°F] = [°C] × 9⁄5 + 32
If a substance is not at its melting or boiling point as the heat content of a sample of matter increases what happens?
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.
Which acid must be added to potassium dichromate to acidify it?
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!
Can bananas be used instead of Potassium chloride supplement?
yes probs as bananas do have potassium in
If you put potassium chloride in the crucible instead of potassium chlorate how would the results turn out?

Can potassium be used for crakers?
If you mean can potassium chloride be used instead of table salt, then yes, though they probably won't taste as good.
Could sodium chromate be used instead of potassium chromate?
Yes, because chemical properties of sodium and potassium ions are nearly same.
Why is the symbol for potassium k instead of p?
It's K because the Latin word for potassium is "Kalium". And the symbol P belongs to phosphor.
What compounds are in Potassium Hydroxide?
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.
