Hydrazine, N2H4, reacts with dinitrogen tetroxide, N2O4: 2 N2H4 (l) + N2O4 (g) → 4 H2O (l) + 3 N2 (g)

When 0.10 mol of hydrazine reacts with 0.10 mole of dinitrogen tetroxide, which of the following quantities would be consumed or produced?

Select one:
a. 0.05 mol N2O4
b. 0.40 mol H2O
c. 0.39 mol N2
d. 0.10 mol N2O4

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.

i believe you are right for all except the 3rd ( look at sqdancefan his answer is much better)

no, the red giant is the hottest with 2.00.000.000 degrees celsius. while the white dwarf only 25,000 degrees celsius.

the electron configuration that you gave me has 16 electrons ergo it has 16 protons ergo it is the element sulfur.
