For the reaction 2na(s) + cl_2(g) = 2nacl(s),
how many grams of nacl could be produced from 103.0 g of na and 13.0 l of cl_2 (at stp)?

Covalent bonds generally form when the bonded elements have a difference in electronegativity less than 1.5. subtract the electronegativities for the following pairs of elements and predict whether they form a covalent bond. electronegativity difference of c and c: ionic covalent electronegativity difference of mg and cl: ionic covalent
