There are different types of food coloring available in most grocery stores- one that is water-based, and one that is oil-based.  The oil-based food coloring works best in chocolates, in fry-oil to color fried foods, and in food with high butter contents.  Based off of this information and knowing that substances of like polarity mix readily with one another, which food coloring is more polar (water-based or oil-based)?  Which food coloring is less polar (or even nonpolar)?

Consider the molecules of furan and benzene. The dominant Lewis structure of furan and the two resonance structures of benzene are shown below: H K Book H What is the meaning of the double-sided arrow () connecting the two structures of benzene? Furan Benzene H It indicates that electrons in benzene rapidly change their positions corresponding to the two structures. It indicates that there are two independent coexisting forms of benzene. It indicates a chemical equilibrium between the two distinct structures. It indicates that the second structure can be obtained as a mirror image of the first one. It indicates that benzene exists in a single form, which is an average of the two structures.

1. An 800g aluminium block cools from 85°C to 30 °C. Calculate the heat capacity, C, of the aluminium block. 2. Construct an energy cycle diagram for potassium fluoride. 3. Determine the lattice energy of potassium fluoride. Enthalpy of atomization of potassium = +89.2kj/mol Enthalpy of atomization of fluorine = +79kj/mol 1st ionization energy of pottasium = +418kj/mol Electron affinity of fluorine = -328kj/mol Enthalpy of formation of potassium fluoride = -561.7kj/mol

Of the bonding forces between atoms and molecules, which are strongest? Select one: bonds between oppositely charged ionized groups hydrogen bonds bonds between polar groups covalent bonds bonds between nearby nonpolar groups
