  • Gloved hand holding an electronic chip with a pair of tweezers. Caption: they call it an artificial leaf.

    To manipulate chemical reactions on a large scale, scientists use stoichiometry to quantify those reactions. The use of stoichiometry ensures there are the right amount of reactants and products. Without it, reactions can be incomplete, with expensive materials wasted and harmful byproducts created. Using stoichiometry, scientists are creating chemicals that take the place of petroleum in fabricating sustainable materials. At a different lab, scientists are mimicking the process of photosynthesis to convert the sun’s energy into storable chemical energy. Part of Chemistry: Challenges and Solutions Series.

  • Two moles strapped together pulling in opposite directions while a bird in a cage is balancing on their backs. Mass-mass Mole-mass. Caption: to figure out mass, find out how reactants work together,

    Using a balanced chemical equation to calculate amounts of reactants and products is called stoichiometry. It is a super technical-sounding word that simply means using ratios from the balanced equation. Topics covered in this program include the metric system, balancing equations, molar conversions, mass percent, empirical formulas, and limiting reactants. Part of the "Chemistry" series.
