Place several pounds of sugar and a gallon of water in a big pot and try to see how much sugar can dissolve in that gallon. Add more and more sugar, and finally it stops dissolving. a. Explain what happened to the molecules of water and sugar at this point.

Remember that temperature is a factor that affects solubility.

b. Describe what you can do to your pot of room temperature sugar water to get more sugar to dissolve, using this factor.

c. Explain the changes at the molecular level.

they are made of gases.

they have a spherical shape.

they make energy through fusion.

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.
