A Science 30 student is provided with three unknown substances. He is told that the identities of them are methanol, methanoic acid, and methyl methanoate.   (Picture attached)     To identify what each of the unknown substances is, he performs a conductivity, litmus, and odour test on each of the substances.   Conductivity Test Litmus Test A. Positive 1. No change B. Negative 2. Red turns Blue   3. Blue turns Red Match the descriptions below to the correct results from the tests above.   conductivity of methanol = ?                                                                                           litmus test of methyl methanoate = ?                                                                                           conductivity of methanoic acid = ?                                                                                         litmus test of methanoic acid = ?

Matter and Measurement

In the universe, there is matter, energy, and void space. The universe contains energy and void space. The definition of matter can be considered as something which possesses mass and consumes space. Chemistry is that branch of science which deals with the study of matter. Under chemistry, nature, composition, and the changes occurring to matter are discussed.
