A sample of wood with a mass of 3.0 grams was burned in an open dish. The ashes weighed 1.2 grams. What happened to the rest of the wood? The remaining 1.8 grams was converted into gaseous compounds. The remaining mass was destroyed. Nothing, the burned wood simply has a mass of 1.2 grams. The remaining 1.8 grams was converted into heat. The remaining 1.8 grams was converted into blastogen.
