2SAS #26-34 and 2SBS #1-8

26. Metallic substances are more likely to lose electrons because they tend to be more reactive and be positive ions.

27. They are chemically inert.

28. a) cation b) cation c) anion d) cation e) anion f) cation g) anion h) anion

29. a) Copper metal and copper ions. I chose this option because the other option compares two substances that chemically contain different things while copper metal is just a certain copper ion that still has the same chemical make up without changing any thing about the substance other than the amount of electrons which frequently fluctuates.

30. 156+254/2= 205 picometers

31. a)oxidation, food coloring
b) reaction between lithium and water, boiling manually by heat source
c) reaction of HCl to Copper causing gas bubbles, H2o at its boiling point becoming a gas

32. a) Bromine b) Silicon

33. The Data is similar because along with temperature or reaction to an acid the amount of metals will go up so the reactiveness is similar as well as the way we constructed the data for the fish kill was by mass of metals and pH while Mendeleev also used atomic mass. He also had to make assumptions just like our class did.

1. Atmosphere- Nitrogen, Oxygen, Argon Hydrosphere- Sulfer, Calcium, Magnesium Lithosphere- Magnesium, Iron, Aluminum

2. Crust, Mantle, and Core.

3. a) Mexico b) Japan c) China

4. China

5. Ores are naturally occurring rocks or mineral that can be mined and from which it is profitable to extract a metal, whereas minerals are the most important continents of the mixture of components found in the ores.

6. Quantity, percent of metal, type of mining and process needed for extraction, distance between mine and metal-refining facilities, supply and demand, environmental impact.

7. The value of gold because it is so unreactive and hardly gets ruined and the possibility of new gold forming because of nutrients being revitalized.

8. Useful Ore refers to the minerals in the ore.
