You have2KClO3 ==> 2KCl + 3O2 as the balanced equation
25 g KClO3 x 1 mole/123 g = 0.20 moles
moles KCl formed = 0.20 moles KClO3 x 2 moles KCl/2 moles KClO3 = 0.20 moles KCl formed
grams KCl = 0.20 moles x 74.5 g/mole = 14.9 g = 15 grams of KCl formed
Nothing is produced, 500g potassium chlorate will be the same 500 g potassium chlorate after reaction. Actually there is no reaction at all.
2 KClO3 ----> 2KCl + 3O2 So 2 moles of Potassium Chlorate produces 3 moles of oxygen molecules or 6 moles of oxygen atoms. 3 moles of Potassium chlorate would thus produce 4.5 moles of oxygen molecules or 9 moles of oxygen atoms.
potassium can make alot of compounds...i know a few... 1. potassium chloride (a healthier alternative to table salt/sodium chloride) 2. potassium nitrate 3. potassium hydroxide (produced when reacted with water)
Hydrochloric acid evaporates off of potassium sulfate when it's produced. This results because potassium chloride is combined with sulfuric acid to create potassium sulfate.
The precipitate would be calcium carbonate, CaCO3.
I Don't knows Sorry

Reddish precipitate of Mercuric iodide and clear solution of Potassium chloride is produced
2 KClO3 ----> 2KCl + 3O2 So 2 moles of Potassium Chlorate produces 3 moles of oxygen molecules or 6 moles of oxygen atoms. 3 moles of Potassium chlorate would thus produce 4.5 moles of oxygen molecules or 9 moles of oxygen atoms.
2KClO3 --> 2KCl + 3O2For every 3 moles of oxygen gas produced, 2 moles of potassium chlorate are used.6 moles O2 * (2 moles KClO3 reacted / 3 moles O2 produced) = 4 moles KClO3
60 percent of the potash extracted in 2003 was produced as potassium chloride, with potassium sulfate and potassium magnesium sulfate--both for fertilizing certain crops and soils--representing the remainder
A 1.80-gram mixture of potassium chlorate, kclo3, and potassium chloride, kcl, was heated until all of the kclo3 had decomposed the liberated oxygen, after drying, occupied 405 ml at 25C when the barometric pressure was 745 torr. This is the problem and the questions were... a. How many moles of O2 were produced? b. What percent of the mixture was KClO3? KCl? Please help!!

Equation: 2KClO3 + Cl2 ---> 2KCl + 3O2 + Cl2 1. Solve for the number of moles of KClO3 in 36.3 g. (.2962 molKClO3) 2. Multiply that value by (3/2), from the equation's coefficients. (.4447 molO2) Note: A BCA table could also be used. 3. Solve for the mass of .4447 molO2. 14.2 grams of oxygen would be produced.
The precipitate would be calcium carbonate, CaCO3.
Oxygen gas is produced. The hydrogen peroxide will decompose to give water and oxygen, potassium Iodide is acting as a catalyst 2H2O2(l) ------> 2H2O(l) + O2(g)
