In conclusion, the mass was conserved in accordance with the law of conservation of mass (LOCOM) because the product weighs the same as both the reactants added together.
What is a scientific observation?
A scientific observation can be defined as an active acquisition of knowledge (information) through one of the sense organs, while using scientific tools and instruments to develop and report a summary of the findings and results.
For this laboratory experiment, we can report a summary of the scientific observation as follows:
Before interaction, we observed that the steel wool weighed 10 grams while oxygen weighed 1 gram. After interaction, we observed that there's a pile of brown particles (iron oxide) that weighed 11 grams.
In conclusion, the mass was conserved in accordance with the law of conservation of mass (LOCOM) because the product weighs the same as both the reactants added together. Therefore, a chemical change occurred.
