To calculate the mass of potassium chlorate containing 40.0g of oxygen, first determine the molar mass of oxygen (16g/mol). Then, use the molecular formula of potassium chlorate (KClO3) to find the oxygen's molar ratio in KClO3 (1:3). Finally, calculate the mass of KClO3 using the molar mass and the molar ratio to find that approximately 186 grams of potassium chlorate contain 40.0g of oxygen.

How many grams of potassium chlorate would be produced by reacting 500 grams of potassium chlorate with oxygen gas?
The reaction between potassium chlorate and oxygen gas generates potassium chloride and oxygen gas. Therefore, the amount of potassium chlorate produced from the reaction is equal to the amount of potassium chlorate that was used, which is 500 grams.
How much potassium chlorate should be heated to produce 2.24 L of oxygen at NTP?
1 mole of potassium chlorate produces 3 moles of oxygen gas when heated, or 1 mole of potassium chlorate produces 1.344 L of oxygen gas at NTP. To produce 2.24 L of oxygen gas, you would need about 1.67 moles of potassium chlorate.
How many grams of oxygen are produced in the decomposition of 6.02g of potassium chlorate?
The decomposition of potassium chlorate produces oxygen gas and potassium chloride. The molar ratio of oxygen to potassium chlorate is 3:2. Therefore, to find the grams of oxygen produced, you would calculate (6.02g * 3 mol O2/2 mol KClO3) * molar mass of O2.
Potassium chlorate--on heating potassium?
Despite that potassium chlorate catches on fire when it gets heated in the open, if you put it in a test tube and heat that, instead of burning it will melt into molten form, and this stage of potassium chlorate is extremely reactive, any contact with anything combustible like sugar would cause combustion of it. This is the basis for the famous gummy bear and potassium chlorate experiment. The sugar in the gummy bear would combust on contact with the molten potassium chlorate, resulting in an violent reaction.
What happen when potassium chlorate is heated?
It would decompose and turn molten. But be careful when you are doing it. Molten potassium chlorate is very nasty stuff. Spill it onto your skin, and it would leave a terrible burn. Potassium chlorate decomposes into oxygen, and when something that could burn, such as a gummy bear, is added to it, it rapidly combusts, driving the decomposition forward. If you spill molten potassium chlorate, you could think of the table, floor, your clothes, your skin, as another gummy bear. So be cautious when working with it.

What if a potassium chlorate sample is contaminated with KCL would the experimental percent oxygen be higher or lower than the theoretical percent oxygen?
If a potassium chlorate sample is contaminated with KCl, the experimental percent oxygen would be lower than the theoretical percent oxygen. This is because KCl does not contain oxygen, so the contamination would dilute the amount of oxygen produced during the decomposition of potassium chlorate.

How do you calculate the theoretical mass percentage of oxygen in potassium chlorate?
To calculate the theoretical mass percentage of oxygen in potassium chlorate, you would use the formula weight of oxygen divided by the formula weight of the compound (potassium chlorate) multiplied by 100. The formula weight of oxygen is 16.00 g/mol and the formula weight of potassium chlorate (KClO3) is 122.55 g/mol. So, (16.00 g/mol / 122.55 g/mol) * 100 = 13.06%.
What if potassium chlorate is contaminated with KCl Would the experimental percent oxygen be higher or lower than the theoretical?
If potassium chlorate is contaminated with KCl, the experimental percent oxygen would likely be lower than the theoretical value because KCl does not contain oxygen. This contamination would reduce the amount of oxygen available from the potassium chlorate during the reaction, thus lowering the experimental yield of oxygen.

What property is it when a potassium perchlorate decomposes to potassium chlorate and oxygen gas?
Since decomposition is a chemical reaction, it would be considered a chemical property.
How would the results turn out if a student forgot to read the label on the jar carefully and put potassium chloride in the crucible instead of potassium chlorate?
If a student accidentally put potassium chloride instead of potassium chlorate in the crucible during a lab experiment, the results would likely not match the expected outcome. Potassium chloride does not release oxygen when heated like potassium chlorate does, so there would be no oxygen to react with the magnesium present in the crucible. This would impact the ability to achieve the desired chemical reaction and may lead to incorrect data or observations.

What if a potassium chlorate sample is contaminated with moisture. Would an analysis show the experimental oxygen higher or lower than the theoretical oxygen?
The experimental oxygen would be higher than the theoretical oxygen in a contaminated sample of potassium chlorate. This is because the moisture would contribute to the sample's weight when measured, resulting in a higher oxygen content calculation compared to the theoretical amount based on the chemical formula.
How many moles of oxygen are produced when 7.5 moles of potassium chlorate decompose completely?
For every mole of potassium chlorate that decomposes, three moles of oxygen are produced. Therefore, if 7.5 moles of potassium chlorate decompose, 22.5 moles of oxygen would be produced (7.5 moles x 3).
