If you heated 100 grams of water to 80 C how much potassium nitrate could you dissolve in it?

Use the equation m1c1(Tf-T1)= - m2c2(Tf-T2)
you get 46.6 C

Is potassium nitrogen oxide having the formula KNO3?
Potassium (K) does not readily combine with potassium nitrate (KNO3).
Where could you find nitrogen in solids?
For example in nitrates as: sodium nitrate, potassium nitrate, uranyl nitrate, ammonium nitrate, etc.
What compound is made by pottasium nitrogen and oxygen?
You could have potassium nitrate KNO3 or potassium nitrite KNO2.
What would calcium nitrate react with?
francium ceasium Potassium Sodium Lithium These metals could react with calcium nitrate in a displacement reaction as they are more reactive. e.g. pottasium + calcium nitrate -> calcium + pottasium nitrate.
What are the hazards of sodium nitride?
Potassium nitrate isn't terribly corrosive or poisonous or anything. It is an oxidizer, specifically a class 1 oxidizer. Potassium nitrate when mixed with something that could burn (sugar, paper, etc) increases the flammability of that product. But potassium nitrate alone isn't flammable.
What changes can you make to potassium chloride to make it dissolve faster in water?
You could grind it into very fine crystals.
How do you separate potassium nitrate from potassium oxide?
Yes. If you mix it with a metal that is higher on the Activity Series of Metals, that metal will replace the lower metal. In our case, Lithium is the only element that is higher than potassium. So, the Lithium would replace the Potassium, forming Potassium and Lithium Nitrate.
Is potassium nitrate or saltpetre considered a natural food preservative?
According to Wikipedia, in the process of food preservation, potassium nitrate is a common ingredient of salted meat, but there are theories indicating that using nitrates in meats can cause cancer. As a preservative it can be known as E252. I am unsure about potassium nitrate, but sodium nitrate has been marked as something we should avoid, but it actually has beneficial properties despite what some "studies" say, it in moderate does is nothing to fear, but instead may be beneficial. Potassium nitrate is still a mystery to me though, i plan to look into though eventually.
Could sodium chloride and potassium nitrate be separated using extraction?
Extraction has no meaning as a specific, particular process. The question makes no sense.
If you used nitric acid to dissolve copper how could you remove the copper nitrate?
Heat the liquid to boil off excess water and the copper nitrate will crystalise out of the solution as it cools. Then filter to separate the crystals from the liquid.
What reactants would give Potassium Nitrate Carbon Dioxide water?
Potassium nitrate, carbon dioxide and water. Looking at the last two reactants, we can take a fairly good guess that this could be a carbonate-acid reaction. Let's try it. We need potassium (ions) somewhere (either in the carbonate or the acid) and nitrate ions in the other. Since all acids must have an H+, the potassium (positive ion) cannot be in the acid. So we must have nitrate in the acid: HNO3, which is just nitric acid. Now the potassium must be in the carbonate, so we balance the ionic formula: K+ and CO32-, and we get K2CO3. So the two reactants are HNO3 and K2CO3, and the equation is HNO3 + K2CO3 --> KNO3 + CO2 + H2O Hope this helped :)
What physical properties would help you distinguish between a pure substance and a mixture?
If you wish to separate the constituents of a mixture, knowledge of the properties the constituent substances will help you figure out how to go about separating them. If you have any property (solubility in water, for example) that applies to at least one of you substances, and doesn't to another, you can use the property to separate them. If you wish to separate a solution, knowing the solubility curves of each solute will allow you to separate by changing the temperature. For example, Potassium nitrate has a much higher solubility in water than sodium chloride at high temperatures, but at or near zero degrees Celsius, it has much less. So, if you had a solution of sodium chloride and potassium nitrate, you could lower the temperature drastically and most of the potassium nitrate will precipitate. This is but one example. If you have a solid mixture, and a certain number of the substances in it will dissolve in water (or any other solvent), washing the mixture with the solvent will dissolve those, leaving everything else behind (you could filter the solvent out to separate the substances which don't dissolve) If your substances are physically different in size, you could pass the mixture through a sieve (for example, to separate sand and gravel). If one of your substances is magnetic, but others aren't, you could use a magnet to separate them.
