N2H4, (hydrazine) is sometimes used as a rocket fuel because it reacts readily with oxygen-containing compounds to produce large amounts of hot gas; one such reaction is 2 N2HQ(1) + N20,() — 3N2(g) + 4 H2O(g). If 3 mol N2H, and 4
mol N204 are available at the beginning of this reaction, which substance will be the limiting reactant?

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.

it should have an internal chamber and two thermometers sticking out of the top. the internal chamber will also be closed off from the outside.
