Security Stud. 1  Full mortise hinges are available with security studs for added safety. 2  With the door in its closed position, a stud attached to one leaf of the hinge projects into a hole in the matching leaf.
Net Ionic Equation. A chemical reaction involves the conversion of reactant atoms or molecules to product. During any chemical reaction, reactant molecules are joined together to form a product which has different chemical and physical properties than the reactants.
Determining The Stoichiometry Of Chemical Reactions. A balanced chemical equation gives the mole ratios of reactants and products in a chemical reaction. How can the stoichiometry of a chemical reaction be determined experimentally? This experiment uses the method of continuous variations to determine the mole ratio of the two reactants.
