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.
Net Ionic Equation Most reactions in an aqueous medium involve ions. However, when a reaction takes place two kinds of ions usually emerge: (1) spectator ions and (2) player ions. The names imply the character of the ions with respect to the reaction.he chemical equation for this reaction is written as: This equation contains all ions in the solution. However, sometimes its necessary to only include those ions that are players and leave out the spectators. A chemical equation that contains only the player ions is called the net ionic equation (nie).
