The forensic technician at a crime scene has just prepared a luminol stock solution by adding 17.0g of luminol into a total volume of 75.0 ml of h2o.. what is the molarity of the stock solution of luminol? (luminol has a molecular weight of 177 g/mol).

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
