When heating KClO3, how could you determine experimentally whether all the potassium chlorate had been decomposed?
**The key word is "Experimentally"

Clarification: When I say decompose, I mean..how do I know "experimentally" whether all the oxgen has left the only leaving KCl

You can determine experimentally when a thermal decomposition is complete by heating and reweighing. If the weight is the same, then your done, if not, repeat until it is.

1. By weighing the remains. You can calculate how much KCl should remain.
2. By adding something that KClO3 would oxidize, and seeing if oxidation happens.

properly, I hate the Lakers & Jackson's a has-been, so I under no circumstances favor to make certain them contained in the Finals, AND the Spurs are my popular team on account that 'ninety 5, so i guess i ought to might want to assert the Spurs vs. the warm temperature. : ) .
