Concept explainers

Mole Concept

Mole concept is a method to determine the amount of any substance that consists of some elemental particles using a grouping unit called ‘mole’. The mole concept enables one to handle the large amount of small elementary particles. The mole concept can be used in many calculations related to mole calculation, molar amount, mole ratio, and so on, which are significant in chemistry.

Two simulations that were used are below: This activity is structured as a game, wherein your challenge is to create correct ionic compound formulas by combining individual ions based on their charges. Once you correctly connect the atoms in the interactive website, a common use for that compound will be revealed. In this worksheet, you must record both the correct formula for each of the seven ionic compounds and their common uses as revealed by the interactive program. Throughout the activity, you will have the option of skipping each compound – if you choose to do this, its common use will not be revealed. You must correctly write the formulas and match the common uses. Website for first simulation: https://www.learner.org/wp-content/interactive/periodic/bonding Click “Begin” on the first page you see. For each compound name listed at the top of the interactive, choose the correct cation and anion which you think belong to the formula for that compound. For example:…
