Thus, to obtain 67.2 L of oxygen at STP, 2 moles of potassium chlorate should be decomposed.
What is the decomposition of potassium chlorate?
Consider the title reaction, the thermal decomposition of potassium chlorate. When KClO3 is heated strongly, it breaks down, releasing oxygen gas and leaving behind a thermally stable (i.e., heat-insensitive) solid residue of an ionic potassium compound.
How many moles are in KClO3?
You can view more details on each measurement unit: molecular weight of KClO3 or grams This compound is also known as Potassium Chlorate. The SI base unit for amount of substance is the mole. 1 mole is equal to 1 moles KClO3, or 122.5495 grams. Note that rounding errors may occur, so always check the results.
How many moles of oxygen are produced when 2 mol potassium chlorate decomposes?
The reaction will produce 3 moles of oxygen gas for every 2 moles of potassium chlorate that decompose. This will be the theoretical yield of the reaction, i.e. what you get when the reaction has a 100% yield.
How many moles of oxygen are produced by the decomposition of six moles of potassium chlorate?
Answer and Explanation:
Therefore, 6 moles of potassium perchlorate will decompose to give 32×6=9 3 2 × 6 = 9 moles of oxygen.
How do you balance potassium chlorate?
- Formula for Potassium chlorate is KClO3 . Formula for Potassium chloride is KCl. Formula for Oxygen gas as molecule is O2.
- ∴ Reaction is : KClO3 → KCl + O2↑.
- Now, balancing the equation, it comes to be : 2KClO3 → 2KCl + 3O2↑.

Is heating potassium chlorate a chemical change?
1 Answer. This process is clearly an example of chemical change.
How many grams is KCl?
Take potassium chloride (KCl) for example. One mol of KCl is equal to 74.6 grams (from the periodic chart, the gram-atomic mass of potassium is 39.0 and that of chlorine is 35.5.
What is the mole ratio of KClO3 to KCl?
Look at the mole ratio you have between potassium chlorate and potassium chloride; what you will see is that every 2 moles of potassium chlorate will produce 2 moles of potassium chloride, i.e. you have a 1:1 mole ratio between the two compounds.
How do I calculate moles?
Use the molecular formula to find the molar mass; to obtain the number of moles, divide the mass of compound by the molar mass of the compound expressed in grams.
What is the mole ratio of hydrogen to ammonia?
Explanation: The ‘Moles” are the coefficients of the molecules in the reaction equation. In this equation the coefficient of hydrogen is ‘3’ and the coefficient of ammonia is ‘2’. So, the ratio of hydrogen to ammonia is 3:2.
How many grams of KCl can be produced from 356 g of KBr?
Cl2 + 2KBr – Br2 + 2KCI How many grams of potassium chloride (KCl) can be produced from 356 g of. potassium bromide (KBr)? 223 g. 814 g.
How many moles of oxygen are produced from one mole of KClO3?
1 mole of KCLlO3 * (3moles KClO3/2moles O2) = 1.5 moles of O2.
How many moles of Zn will be needed to completely react with 0.4 moles of HCL?
0.2 moles of zinc metal are required for reaction with 0.4 moles of hydrochloric acid.
How do you do stoichiometry?
Almost all stoichiometric problems can be solved in just four simple steps:
- Balance the equation.
- Convert units of a given substance to moles.
- Using the mole ratio, calculate the moles of substance yielded by the reaction.
- Convert moles of wanted substance to desired units.
