RedOx

Today we learned about the different types of RedOx. This includes synthesis, decomposition, Single replacement reactions, and combustion. They are different from double replacement reactions because they have a different chart we need to use.

Solubility Lab fun

Today we did the solubility rules lab. It was a lot of fun to see chemical reactions take place right in front of us and knowing that I made that happen. I learned a lot about the solubility rules in this lab because they were essential to doing the lab.

Empirical formula

Today we learned empirical formulas! An empirical formula is finding the subscripts to a chemical formula. These are the steps to finding the empirical formula.

1st: calculate the empirical formula mass

2nd: divide thee E.F. mass into the gram formula mass and get a whole number.

3rd: distribute the whole number to the empirical formula.



Formula of a chloride

Today we did the lab Formula of a chloride.  First we measured the weight of the beaker in grams. Then we added zinc to the beaker and measured its weight. Then we added HCl to react with zinc as we heated it. Then once all the liquid was gone. we measured the weight of the remaining material.

Pre lab for hydrant

Today we did the Hydrant lab. My partner and I failed to pass the Pre lab but the concept was not that hard. Its some pretty simple math that you need to do for it. I completed the lab with the given data from Mrs. Frankenburg fairly quickly.

pre test for chemical composion

This test was very hard. I arrived a little late first of all but time wasn't the issue on this test. I had absolutely no clue what this unit was about. I didn't know the main thing in this pre-test. We previously didn't learn on how to convert from moles to mass and mass to moles and the test had like 30 of those questions. The only thing I did on this test was guessing. I knew about the last couple questions as they didn't have to ado much about moles. I have never used moles before so I didn't know what to do with them. A mole is a pretty big number and I have no idea what it represents. I am not looking forward to this unit. I don't like the fact that we have two tough units in a row and that could be terrible for my grade. I actually did surprisingly well on my unit exam for last unit, which was measurement. I think my grade is safe but, not for long...

main meal 2



Ingredients:
237ml light corn syrup
113 grams sugar
59ml butter melted
5ml vanilla
3 ovum
227 grams semi-sweet chocolate chips
340 grams pecan halves



heat oven to 163C. in large bowl combine corn syrup sugar margarine vanilla and ovum, beat well. spread evenly into, pie crust lined, pie pan. bake at 163C for 55-65 minutes. cool completely.

main meal 1

This is my main course, it is complicated because the food i chose is a pie. So I labeled the crust as my main course.



Ingredients:
454 grams all purpose flour
4 grams of salt
152 grams shortening
105 ml ice water



in medium bowl combine flour and salt. then cut shortening into flour. sprinkle flour mixture with ice water 15 ml at a time. add until dough is moist enough to form a ball. then roll out into flat sheets.

Appetizer

907 grams of apples
237ml of water
113 grams of sugar
4.2 grams of cinnamon

In a heavy pot heat apples and liquid over low heat. cook about 20-30 minutes depending on variety until apples are very tender.
