10. How many grams of NH 3 can be produced when 67.2 L of nitrogen, , are used? Assume you have N 2 hydrogen in excess. Be sure to balance the reaction. 12. A chemistry student reacts solid magnesium and hydrochloric acid together in a flask (equation below). A universal pH indicator (turns solution pink when acid present) was placed in the flask with the hydrochloric acid, and then the magnesium was dropped in the hydrochloric acid. Given the student's data/ observations below, what conclusion can be made regarding what the limiting and excess reactant was in this experiment?

vanderwaal's forces of attraction are the electrostatic intermolecular forces that exist in a molecule due to the temporary or permanent dipoles that are developed in a molecule. in , the major intermolecular forces are dipole-dipole interactions as the molecule is polar (bent structure). so the vanderwaal's forces of interaction in between molecules are the permanent dipole-dipole interactions that develop due to the dipole that exists in between the polar h - s bond. the positively charged hydrogen atom is attracted towards the negative end of the dipole that is sulfur of the adjacent molecule. therefore, these forces of attraction are relatively stronger than that of london dispersion forces that exist in non polar molecules.
