CH110 Lecture Notes - Lecture 4: Chemical Equation, Strong Electrolyte, Significant Figures
Document Summary
Addition and subtraction equations final answer rounded to the least number of decimal places in the given numbers. Multiplication and division equations final answer rounded to the least number of significant figures in the given numbers. Stoichiometric coefficients represent the numbers of atoms, molecules, or moles of reactants or products. Balance elements that occur in one compound first. 4nh3 + 5o2 4no + 6h2o. C5h12 + 4o2 5co2 + 6h2o. Solution homogeneous mixture made up of a solvent and a solute. Solvent solution component in which one or more solutes is dissolved. Determines the state of matter in which the solution exists. Solute solution component that is dissolved in the solvent. Solution may have several solutes, with the solutes generally present in lesser amounts than the solvent. When a solid is put into a solvent interactions between solvent and solute particles compete with the interactions among the solute particles themselves.
