WebJul 30, 2024 · 6.6: Mole-Mass and Mass-Mass Problems. To convert from mass or moles of one substance to mass or moles of another substance in a chemical reaction. We have established that a balanced chemical equation is balanced in terms of moles as well as atoms or molecules. We have used balanced equations to set up ratios, now in terms of … WebDecomposition reactions allow lots of opportunities for practical work or demonstrations. Using these question sheets, learners can apply their knowledge to questions that link decomposition reactions to word equations, symbol equations and conservation of mass. There are two versions of the worksheet.
