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.
First you have to write the entire equation (including states): CuSO4(aq)+ 2NaOH(aq) -> Cu(OH)2(s) + Na2SO4(aq) Now you have to write an ionic equation which involves splitti â¦ ng up each compound, that is in aqueous form, into it's parts and writing the charge of each part: Cu(aq)2+ + SO4(aq)2- + 2Na(aq)1+ + 2OH(aq)-1 -> Cu(OH)2(s) + SO4(aq)2- + 2Na(aq)1+ Now to write the net ionic equation, you cancel out any thing that is the exact same on both sides of the equation (same state ...
