Help Please! Due tonight When 1.1323 g of an organic iron compound containing Fe, C, H, and O was burned in O2, 2.1179 g of CO2 and 0.60611 g of H2O were produced. In a separate experiment to determine the mass percent of iron, 0.2686 g of the compound yielded 0.06069 g of Fe2O3. What is the empirical formula of the compound?

Spontaneity tell us the direction of the reaction, but not how fast it goes. gibbs free energy brings together enthalpy, entropy and temperature in one easy formula. g = h - ts. and, finally the sign of delta g is always negative for a spontaneous reaction.

The state or quality of being humid.a quantity representing the amount of water vapor in the atmosphere or a gas.

Vander waals forces are inter molecular bonds that exist within molecules of the same substance. a water molecule is made up of oxygen and hydrogen atoms which share electrons between each other. the vander waals forces are forces that exist between multitude of different  molecules of water. dipole dipole forces is the type of vander waals force that exist in water. the oxygen atom which is more electronegative pulls the shared electron closer to itself thus generating a partial negative charge while the hydrogen acquire a partial positive charge. these two different charges causes attraction to occur in water molecules.
