Determine the weight of kclo3 heated
Did you know?
WebA sample of a mixture of KClO3 and KCl weighs 5.454 grams. When it is heated several times, the final mass of the mixture weighs 4.348 grams. The reaction that occurs is the loss of O2(g) to the air from KClO3 producing KCl. The unbalanced equation is shown below. What is the weight/weight percent of the KClO3 in the mixture? KClO3 → KCl + O2 WebTherefore, the weight percentage of KClO3 in the sample is 55.8%. 8. To solve this problem, we need to use both the ideal gas law and van der Waals's equation to calculate the pressure expected for 25 mol of CHF gas in a 5.00-L container at 75 °C.
