Chlorate-based propellants are more efficient than traditional gunpowder and are less susceptible to damage by water. Weigh the cooled crucible, lid and sample after this second heating and record the mass. Add approximately 1 gram of potassium chlorate to the crucible. So for 62 moles of KCl produced that means 62 moles of KClO3 were required: 62 moles KCl x (2 moles KClO3/2 moles KCl) = 62 moles KClO3. Remember that most items look exactly the same whether they are hot or cold. Potassium chlorate was one key ingredient in early firearms percussion caps (primers). These solids are all dissolved in distilled water. [citation needed] It is a far cheaper source than a pressurized or cryogenic oxygen tank. A method that often works is to balance everything other than #"H"# and #"O"# first, then balance #"O"#, and finally balance #"H"#.
