Using Audience Awareness to Contextualize Your Research Goals. A persuasive problem statement consists of three parts: 1) the ideal, 2) the reality, and 3) the consequences for the reader of the feasibility report. Well constructed problem statements will convince your audience that the problem is real and worth having you investigate.
A chemical reaction is a process in which one set of chemical substances (reactants) is converted into another (products). It involves making and breaking chemical bonds and the rearrangement of atoms.
A chemical reaction involves a chemical change, which happens when two or more particles (which can be molecules, atoms or ions) interact. For example, when iron and oxygen react, they change to a new substance, iron oxide (rust). Iron oxide has different chemical properties to iron and oxygen.
