A couple major misconceptions are students do not understand the multiplication process using a coefficient. The class was divided into groups of 3 people per group and our objective was to go through the process of determining the number of atoms that reacted when hydrochloric acid was added to zinc. Definition of Molecule. The same process is used to count aluminum cans when you take a bag to the recycling center. Rules for Counting Atoms 13. Test. Students must use what they have learned, including the ability to recognize that chemical formulas are used to identify substances and determine the number of atoms of each element in chemical formulas containing subscripts; to investigate how evidence of chemical reactions indicate that new substances with different properties are formed; and Students explore the science of microbial fuel cells (MFCs) by using a molecular modeling set to model the processes of photosynthesis and cellular respiration—building on the concept of MFCs that they learned in the associated lesson, “Photosynthesis and Cellular Respiration at the Atomic Level. 2 days ago · Units, Lab Equipment, & Measurements - Self-Assessment Sheet Atoms Atoms Overview Sheet Atoms - Self-Assessement Sheet Counting Valence Electrons Electron Dot 2-7: Counting Atoms 1.
