We choose to examine students’ understanding of matter and energy in concert for a number of reasons. Although energy is not an object or a substance, it must be identified by its association with objects and substances or changes in objects or substances. In much of K-12 chemistry, the ...
A chemical formula is a simplified, standard notation for explaining a chemical reaction used in experiments. They may look complicated, but when you learn how to read them, they become fairly self-explanatory.
While my reactions were running, I loved chalk-talking chemistry at the blackboard with other chemists. I have never worried about security, or what the future might bring. 翻译: 我的性格使我乐观拥抱不确定性。实际上...
This paper investigates the views of science and scientific activity that can be found in chemistry textbooks and heard from teachers when acid–base reactions are introduced to grade 12 and university chemistry students. First, the main macroscopic and microscopic conceptual models are developed. ...
Despite this, new chemical insights continue to be uncovered, including recent findings that may explain newly discovered functions for many DNA polymerases in DNA repair and mutation. Some of these reactions involve non-Watson–Crick base-pairing. In addition, certain DNA polymerases have been ...
