Blog 11.1: Activity Series

1a.Nitrate is a "spectator ion" because it doesn't do any of the reacting, it stays the same.
1b. Mg is oxidized, Ag is reduced.
2. If X is higher than Y+2 on table J, it will react.
3. An activity series is a list of elements in order of their reactivity. An activity series is used to predict which metal is more reactive than than another. This is done by looking at table J. The higher the element on the chart, the more reactive it is. If an element is lower than another, the element is less reactive.
4. Gold, silver, and copper aren't very reactive, so when they are found, they're in their purest form. The more reactive metals turn into ions by reacting with things like oxygen. This means when they're found, they aren't in their purest form. Instead, they're an ore.
5.Copper ore was mixed with charcoal and iron ore in a furnace. This reduced the ore to pure copper. Initially bronze was made out of copper and arsenic to form arsenic bronze.

Enrichment: Ag+1 Is used in photography to create images. The part of the image that is sensitive to light uses silver salts to burn and trap the image.

Blog 10.1 And 10.2

1. Salt, sugar, and methyl alcohol. They're soluble in water.
2. Acetone, wax, and lighter fluid. They're insoluble in water.
3. Ethanol is less polar than water.
4. Yes, I would expect ethanol to dissolve in water. I don't think hexane would dissolve in water.
5. NH3- Polar, Dissolves in water, Doesn't dissolve in hexane
    I2- Non polar, Doesn't dissolve in water, Dissolves in hexane
    HCL- Polar, Dissolves in water, Doesn't dissolve in hexane
6. Because water is polar, polar molecules will dissolve in it. Hexane is non polar, so they won't dissolve in it.
Enrichment: When CO2 dissolves into water, it happens slowly on the surface of the water. The CO2 crosses from the air into the liquid. It then reacts with the water. CO2 + H2O H2CO3 If this reaction didn't happen, all aquatic life would die because fish and plants underwater take the O2 and CO2 out of the H2O. 

10.2 Section


The temperature made a big difference in how fast the KCIO3 dissolved. In order to make it dissolve faster, you need to increase the temperature. Doing this makes particles have less attraction to each other, move faster, and have more effective collisions. Unsaturated = Little to no solute. Saturated = Max amount of solute. Super Saturated = More than the max amount of solute. To make rock candy, boil water and sugar in a pan. Mix them until the sugar is dissolved in the water, making a saturated solution. When cooled, the solution turns super saturated. This is what forms the crystalline structure you see in rock candy.
