How do you name compounds given chemical formulas? Molecular compounds are named with the first element first and then the second element by using the stem of the element name plus the suffix -ide. Numerical prefixes are used to specify the number of atoms in a molecule.
How do you write chemical names?

How is SWL of D shackle calculated? The formula used to find the Safe Working Load (SWL) of shackles is Diameter of shackle2 x 3. As determined by the vector diagram, the SWL in this example is 5.1 tons. Dividing 5.1 by 3 gives 1.7. … The proper size shackle will be the one just larger than 1.3″, in this case, the 1-3/8″ shackle.
