  1. Adding Ions Cause there’s no youtube video 

  2. NaCl+KF NaCl+KF ????? Na1+Cl1- + K1+F1- Na1+F1-+K1+Cl1- The charges balance out so there’s no need to fix it! Notice how you add the first and last elements together and the two elements in the middle

  3. NaCl+MgO Na1+Cl1-+Mg2+O2- • Na1+ O2-+Mg2+ Cl1- BUT WAIT! The compounds arent neutral now!!! So we criss cross and get this! Na2O+MgCl2

  4. NaO2+K3N Before we go on, I must address a couple of things. First, to get the effective charge (in other words, the charge of the element that we use) multiply the subscript (x) by the charge, so Na2has a charge of 2 but just normal old Na has a charge of 1. if that makes any sense Na21+O22-+K31+N3- Secondly, when dealing with 2 molecules with a subscript, when you add them together, you must first get rid of the subscript (especially if the subscript is greater than 3) so let’s say we have a product like Na2 O4you are going to want to get rid of the subscript first, so it reads NaO, then you can continue to criss-cross, and because neither of the elements has a subscript you criss cross by the original charge of the element.
