Step 1) convert mass (m) of KClO3 to moles (n) using molar . A friend argues that if mass were really conserved he would never need to refill his gas tank. Take a loose, frayed out 2-3 centimeter piece of steel wool and hold it in a Bunsen burner flame for a very brief instant with your crucible tongs (it will glow red). Among the unique chemical properties of oxygen are its ability to support respiration in plants and animals, and its ability to support combustion. Scientists accidentally discover photosynthesis doesn't work exactly like we thought it did, Stressed plants 'scream,' and it sounds like popping bubble wrap. So, in order to find the volume of oxygen gas at STP, you need to know how many moles of oxygen are produced by this reaction.
