Is the chemical reaction exothermic, endothermic, or neither?
In this experiment, you will measure the heat energy released or absorbed by the chemical reaction of rusting, the transformation of iron and atmospheric oxygen into iron oxide. Before you begin, make an educated guess about the outcome of this experiment based on your knowledge of rusting. This educated guess, or prediction, is your hypothesisAn idea in the form of a statement that can be tested by observation and/or experiment..
