Recently, I have completed taking the 10.1 and 10.2 notes for chemistry. I have also completed two tests for my sociology class. And have completed the tests for parcc.
Recently I have learned that a solvent is what the solute is dissolved in and the solute is what can be dissolved. I have also learned the difference between saturated and super saturated. Also how to make ice cream! In my sociology class I have learned how elders are looked upon in today's society. In some cultures however, elders are considered wise and intelligent. I have also learned that drugs and alcohol accidents occur every 53 mins.
Next I plan to study hard for my chemistry test and also my sociology and psychology tests. I also plan on studying my notes to make sure I have a clear understanding of everything.

Precipitant explore blog
A precipitate is formed from a liquid solution, but is initially a insoluble solid, which means it does not dissolve. It is also typically ionic. Temperature plays a major role in what makes a precipitate. For example, lowering the temperature can form a precipitate. In our lab, we observed that salt, being a solute, allows for the temperature to be lowered, however it does become a solid precipitate.
An aqueous solution is where the solvent is water. The anions and the cations are combined to form a insoluble ionic solid called a precipitate. A method that we use to identify whether this occurs are called solubility rules since not all aqueous reactions form precipitates.
The solubility rules are
1. NO3- : Nitrate's are ALWAYS soluble
2. Alkali metals are ALWAYS soluble
3. Ammonium is ALWAYS soluble
In the lab, the precipitates that were formed were CuSo4, FeCl3, Pb (NO3)2, and AgNo3.
Non- precipitates were CaCl2, HNO3, NaCO3, and NH3. Evidence that also supports that Nitrate's are always soluble is that Pb (NO3) produced a precipitate when combined with the other chemicals the majority of the time. Evidence that supports that Alkali metals are always soluble is that KI produced a precipitate with other chemicals. The evidence that proves that ammomium is always soluble is that NH3 (aq)+H(aq)=NH4 (aq) .

Solutions Explore blog
A solution is a mixture where the solute is distributed within the solvent. A solvent is what the solute is dissolved in. The solute is what can be dissolved.
Dissolving is when the solute has broken down into smaller molecules, from the large molecule it once was, after it has made contact with the solvent.
In conclusion, my results each demonstrated something different in each part of the lab. In part A, we were able to identify when a solution is saturated, or super saturated. When a solution is saturated, it means that the solution has dissolved nearly completely and cannot be dissolved anymore. In my results, the sodium acetate was saturated because it dissolved in the water and it could not be dissolved anymore. However the heated test tube results were that it was super saturated because it completely dissolved because the heat created more energy and allowed for the molecules to be broken down faster.
In part B, we concluded that like dissolves like. The glucose had not dissolved in the Benzene but dissolved in the water. The water was polar and the Benzene was non-polar. Therefore, if a substance was polar it would dissolve in water and whatever was non-polar, would dissolved in the Benzene.
In part C, we were able to identify what can conduct an electric current using electrolytes. The glucose and DI water, did not produce electricity, because there were no electrolytes. Sodium chloride, and tap water both produced electricity. However, Sodium cholride produced a higher conductivity because it had stronger electrolytes than the tap water. The tap water was not as bright as the sodium chloride also because it produced fewer ions.

3 question blog 4/8
Recently I have completed two tests for sociology, and psychology. I have also completed my outline for my essay in english.
Recently, I have learned about thermochemistry and how the phase diagram fits into it. I am also learning how to convert unit measurements to help solve direct or indirect problems (Boyles, Charles', and Gay Lussacs law). I have also learned that people who are deaf aren't seen as having a disability because they're their own ethnic group which makes several people interested in how they communicate and want to learn more about their culture.
Next, I plan to study really hard for my sociology test. And to mentally prepare myself for the rest of the semester. I'm also going to study for the thermochemistry test that's coming up soon. I will also develop better study skills and try my hardest to stay on task.
