3 Questions (11-30-12)

This week I learn how to do ionic equations, a little bit of Methasis Reactions, I'm learning about the Solubility rules, because I still don’t know how many are there. Precipitation and I learn I class about Molarity, how to go from mL or moles to mL and then to Liters, but I still have to take notes about that.

This week I finish 4 quick labs about solubility rules, methasis, redox, and Activity series. Mixing Solutions, with metals, acids and bases. Find their net ionic equation and find their reduction and oxidation.  Tuesday I did 2 and Wednesday I did two more. I took a picture and a video of each lab to finish it at home.

This weekend I'm going to try to finish the notes, because I'm just in methasis reactions. I need to do 2 more or 3 and the flip questions for all the notes. I'm going to print the new lab we are doing on Monday and do the pre-lab for it. I need to finish the 4 labs that we did thisweek. Learn when the products in a reaction will be a (aq) or a (s). I'm going to try to read my book this weekend, I was going to read it this week but I didn’t have time.

Chemical reactions

People should be careful with chemical reactions because they can do something good or something bad after the reaction. Like in some restaurants or homes they still mix Clorox and Ammonis to clean, until is too late and there's people dead or in a hospital. Those 2 things make chlorine gas and other bad things that can kill you. We use chemical reaction like burning gasoline for cars, but they dont do anything bad or using copper as tubes for water. Those 2 dont do anything bad to kill you.

3 Questions (11-23-12)

This week i went to school only for 2 days, Monday and Tuesday, because of thanksgiving break, the rest of the week i had to work. After i got out from work i took notes about "Net ionic equations", finish my extra credit, and finish my 2 blogs.
This week i learned how to make a net ionic equation, after watching the video i think making those equations are easy. When i was doing my UT extra credit i remember to things that i forgot, like founding the percent abundance of isotopes, i had trouble doing that question but not i get it.
Next week or tomorrow i think im going to learn what i should do if a see a (g) in an equation instead of a (aq) or a (s). Tomorrow morning im finishing my UT homework and my lab notebook. Next week or this week im really going to read my book and finish it, i was going to read it on thanksgiving break but i didnt had time.

What I am thinking of? (11-12-12)

At this moment I feel free from all the stuff I was doing, with school, cross country, and work. Now that cross country is over I can focus more in school and do better in chemistry, the class I'm doing a little bit bad, and another classes. I'm going to do all my work; I could read my entire book in thanksgiving week. And finish any missing work.

Baby bottle lab (11-7-12)

In the baby bottle lab I succeed getting to 6 meter and more. I took 2 trials at the beginning just to mess around and then I went home to do some calculations and I got it at the second trial. At the beginning I didn’t know if I had to use more vinegar than baking soda, or more baking soda than vinegar, but when I trial both ways the baby bottle went the same distance. I had to use stoichimetric to find how many grams of Carbon Dioxide I can produce with 3 grams of baking soda. And then with that number of grams of carbon dioxide fined how many grams of vinegar I can make with that #of grams of CO2. I don’t think I would change anything, my went really far, I would try with 2 grams or 1 grams of baking soda, but I think it would that same ratio as mine.

3 Question (11-9-12)

This week we finish the baby bottle lab and i  got to 6m. The way i did it is finding how much CO2 is in 3g of Baking soda. Then, i had to know how much vinegar in the amount of CO2 i got from 3g of baking soda. Because the vinegar is not pure vinegar i had to multiply the amount of vinegar times 10, because there is 10g of pure vinegar in every 100g of vinegar. I multiply the by 4 the amount of baking soda and vinegar to get amount to get 6m and pass it to get almost 12m
This week i really didnt learn anything new in science, but im getting better in finding a limiting factor and all that.
Next week or this 2 days until monday im going to study for the exam

3 questions (11-4-12)

This week we start practicing with the baby bottle lab, but we didnt start because the class ended. Monday we will start practicing.
Im still learning how to get the limiting reaction of a chemical reaction.
Next week i want to start reading my book because im just in the 9th page. I want to start and finish the baby bottle lab and to learn more stoichiometry.
