Use "unreacted" in a sentence
"One particularly unusual finding in this research article was that the percentage of "red/gray chips" of supposedly "unreacted thermite" amounted to approximately 0.1% of the total mass of the collected dust."
"Assuming that most of the "thermite" would have burned when set off, and only a fraction remained unreacted, then the amount of 0.1% of the total dust is astounding."
"The paper ends with this sentence: “Based on these observations, we conclude that the red layer of the red/gray chips we have discovered in the WTC dust is active, unreacted thermitic material, incorporating nanotechnology, and is a highly energetic pyrotechnic or explosive material.”"
