When sugar is heated it melts and then caramelize giving of water. After this, it turns blank (carbon) and then coverts to co2 (carbon dioxide) .
So, heating of sugar is an endothermic , decomposition and oxidation reaction.
  When Ammonium Chloride is heated , it directly goes from solid state to vapour state without changing into liquid state.
So, heating of Ammonium Chloride is an example of sublimation reaction.

Some people might argue that an orange is a high energy food. Others would disagree and consider a cup of pasta to be a high energy food. How is it possible for both groups of people to argue their position and be correct? Based on the actual biochemistry of the molecules involved, which food has a higher energy content? Explain?

Answer is: pasta has a higher energy content.

Main component of pasta is flour and main component of flour is starch.

Starch (carbohydrate) is a polymeric carbohydrate consisting of a large number of glucose units bonded by glycosidic bond. Starch is a white, tasteless and odorless powder that is insoluble in cold water or alcohol.

Food rich in carbohydrates has high energy content, because human body can digest it very fast.

Orange has a lot of cellulose (also carbohydrate), but human body cannot digest it.

Based on what you have now learned about biochemistry, predict which one of the three types of carbohydrates (monosaccharide, disaccharide, or polysaccharide) would have more energy stored in its structure. Explain your answer.

A polysaccharide will have the most energy as it has the most number of bonds that have stored up chemical energy in them.

Explain in a situation in which the reactant might weigh more than the product

In nuclear reaction, like nuclear fission or nuclear fusion, matter conversion takes place.
This means that the reactants of the equation form new elements as products and a huge amount of energy is released.

Based on this, nuclear reaction are the type of reactions in which the reactant might weigh more than the product.

What is the final temperature of 78g sample of water at 99°C if it loses 6500 J of heat energy?

The specific heat of water is 4.184 J/g/°C,
Therefore: 78 g of water at 99°C loses 78 (4.184) = 326 J per °C. 
(6500) J / (326 J/°C) = 19.93 °C
So the final temperature is 99-19.93 = 79.07 °C

The liquids hexane and water are placed in a test tube. The test tube is stoppered, shaken, and placed in a test tube rack. The liquids separate into two distinct layers because hexane and water have different (1) formula masses (2) molecular polarities (3) pH values (4) specific heats

Answer is: (2) molecular polarities.

Hexane is alkane (acyclic saturated hydrocarbon, carbon-carbon bonds are single) of six carbon atoms.

Hexane (C₆H₁₄) is nonpolar molecule.

Water (H₂O) is polar molecule.

Bonds between oxygen and hydrogen atoms are polar covalent chemical bonds.

Water is polar because of the bent shape of the molecule.  

Oxygen atom in water molecule has sp3 hybridization. The bond angle between the two hydrogen atoms is approximately 104.45°.
