Formula unit ionic compounds are not found as single molecules. the simplest ratio of cations to anions Example: ZnCl2 represents the simplest combination of zinc and chlorine: one Zn 2+ ion and two Cl- ions WATER Contains polar covalent bonds. Called the “universal solvent” “Like dissolves ...
The teacher and the two coteachers coplanned, cotaught and coevaluated lessons in chemical bonding in a grade 10 upper secondary class. Findings indicate that the coteachers contributed with their own learning experiences to help the teacher understand how students perceive difficult concepts. In ...
of a class of Year 10 students' learning outcomes based on the proposed teaching sequence and emphases. Throughout the learning of the topic 'chemical bonding' which spanned two months, three students ranged from the highest to medium achieving students in the class were selected for interviews...
(which are usually differentiated in mass using isotopes) are added onto the sample using biochemical reactions. Chemical labeling usually targets either intact proteins or biochemically digested peptides, and is achieved via chemical bonding with amino acid side chains (e.g., lysine and cysteine),...
This research aims to find a computer-based two-tier multiple choice diagnostic test of student misconceptions on chemical bonding. The process of developing diagnostic test is conducted by: (1) analyzing student misconceptions on chemical bonding including analysis of the literature of previous journals...
