Chemistry is the science that seeks to to discover the relationships between the particle structure of matter and the properties of matter that we observe. Scientific MethodA process for trying to understand the material world by observing the way it behaves and by conducting experiments to test our ideas.What is Chemistry? Intro-Ch 1 Page 1A scientist notices that when burning a certain metal in a closed container, the mass of the entire container stays the same.A.The scientist performs many controlled tests, carefully measuring the masses before and after many chemical reactions.B.The scientist finds that the mass will stay the same during ANY chemical reaction as long as it’s in a closed container.C.This may be because substances in the air combine with the metal when it burns.D.The work done confirms that all matter is made of atoms, and these atoms rearrange and recombine during chemical reactions.
