If the reaction equation is KClO4 -> KCl + 2 O2, as will occur at sufficiently high temperature, 2 moles of O2 will form from each gram formula mass of KClO4. This formula unit mass has the value 138.55; therefore, the number of moles of diatomic oxygen formed will be 2(3/138.55), or about 4 X 10-2 moles. If the integer 3 is considered exact, more significant digits are justified, and the answer can be better approximated as 4.3306 X 10-2

What is the skeleton equation for potassium chlorate and oxygen gas?
KClO3 --> KCl +O2 - hence the use in explosives chlorate normally made by action of Cl2 on KOH. Another contributor says:- KCl + O2 gives rise to KClO3
In the reaction MgCI2 plus 2KOH Mg(OH)2 plus 2KCI if 3 moles MgCI2 are added to 4 moles KOH what determines how much Mg(OH)2 is made?
The potassium hydroxide is what we call the limiting reactant. 4 moles of potassium hydroxide react with 2 moles of magnesium chloride. The third mole of magnesium chloride is in excess and has no effect.
What is the composition of a matchstick head?
Strike anywhere matches contain P4S3, phosphorus sesquisulfide. The safety match has chemicals in the striking area which incudes red phosphorus and the match head contains potassium chlorate and sometimes antimony(III) sulfide
In the reaction MgCl2 plus 2KOH---MgOH2 plus 2KCl if 3 moles MgCl2 are added to 4 moles 4 KOH what determines how much MgOH2 is made?
Potassium hydroxide is the limiting agent.
What is the molarity of a solution that is made by dissolving 75.0 grams of MgCl2 in 500.0 milliliters of solution?
Need moles MgCl2 75.0 grams MgCl2 (1 mole MgCl2/95.21 grams) = 0.7877 mole MgCl2 ================now, Molarity = moles of solute/Liters of solution ( 500.0 milliliters = 0.5 Liters ) Molarity = 0.7877 moles MgCl2/0.5 Liters = 1.58 M MgCl2 solution --------------------------------
Is potassium chlorate an element?
Potassium chlorate is a compound, which is a chemical made by putting together element bonds. So whilst potassium chlorate is a compound, what makes it contains element atoms.
How many moles of oxygen are produced from 14 moles of potassium chlorate?
2KClO3 + heat -> 2KCl + 3O2 14 moles KClO3 (3 mole O2/2 mole KClO3) = 21 moles oxygen made This is a common industrial method of producing oxygen.
What chemical element is found at the tip of the matchsticks?
Matchsticks is a mixture of antimony trisulphide, potassium chlorate white phosphorus with some glue and starch is applied on the head of the match made of suitable wood.
What is the skeleton equation for potassium chlorate and oxygen gas?
KClO3 --> KCl +O2 - hence the use in explosives chlorate normally made by action of Cl2 on KOH. Another contributor says:- KCl + O2 gives rise to KClO3
What is bullet primer made of?
Primers for CARTRIDGES (bullets are the part that comes out of the barrel) are made of a material that explodes into flame when struck. That material has, in the past, included fulminate of mercury, and potassium chlorate. Modern primers are generally made from lead azide.

What is the molarity of a 2.000 L solution thatis made from 14.60 g of NaCL?
Find moles NaCl first.14.60 grams NaCl (1 mole NaCl/58.44 grams)= 0.2498 moles NaCl================Now,Molarity = moles of solute/Liters of solutionMolarity = 0.2498 moles NaCl/2.000 Liters= 0.1249 M NaCl solution--------------------------------
What is the volume of 3.0 M solution of NaCl made with 526g of solute?
Need to find moles NaCl. 526 grams NaCl (1 mole NaCl/58.44 grams) = 9.0 moles NaCl --------------------------------now, Molarity = moles of solute/Liters of solution or, for our purposes Liters of solution = moles of solute/Molarity Liters of solution = 9.0 moles NaCl/3.0 M = 3.0 liters in volume ---------------------------------
