Again, use the same TC and MC functions. (They are repeated below).  What is the average variable cost at a quantity of 10?

The demand for salt is relatively price inelastic, while the demand for pretzels is relatively price elastic. How can you best explain why?

Compare the two Lewis structures shown (Structure A and Structure B). Which do you predict to have a higher boiling point and why? Structure A Structure B Same boiling point Because more energy is required to overcome the dipole–dipole interactions compared to LDF. overcoming hydrogen bonding interactions require more energy than overcoming dipole–dipole interactions. They have the same molecular geometries therefore they will have the same types of interactions requiring the same energy.

Chlorine (Cl2) and fluorine (F2) are both gases at room temperature. Which do you predict to be more soluble in water at this temperature and why? Cl2 F2 Because It is smaller and can fit better between water molecules. It can form H-bonding interactions with water. It forms stronger dipole-induced dipole interactions with water.

Why does heat go from hot to cold but not from cold to hot?

Choose the process that is endothermic from the list below. 

What are the intermolecular forces present within this substance, shown in the first question, as a liquid? 

The melting point of gold (Au) is 1337 K. What are the signs of ΔH, ΔS, and ΔG for gold melting process at 1000 K? Table of Choices ΔH ΔS ΔG A + + + B + + – C – – – D – – + E + – +

Which ionizing radiation type differs from an x-ray only in where it originates?

The design of an x-ray tube requires that electron flow through it is in a single direction or phase. If alternating current were supplied to the x-ray tube at high voltage, what would be the result?
