Today Dr. B reviewed over the homework that we turned in today. She went over most of the problems we had a hard time understanding, and she explained it to those who needed help with the problems. She showed us a trick in balancing chemical equations.
i.e. if carbon and hydrogen are one compound and a reactant and hydrogen has an even subscript then we should put 2 infront of carbon: 2C2H14
Thank God Dr. B postponed the test. Its not tomorrow so no need to cram tonite!!!!!!!

No test tomorrow equals no cram session for me
ReplyDeletewebsite worksheet on balancing equations

The next test will be comprised of this chapter and the next chapter, so keep reviewing ch 8 because we still need to know it.
ReplyDeleteSo, I can guarentee no one is as happy as me that the test got postponed, hwoever; the next test will be in approximately 1 to 1 + 1/2 weeks, so be ready for a big test. Material will be over Chap. 8, and Chap. 9. Also, don't forget homework assignment is to read 9.1 and 9.2 for tonight. have a great night guys!
ReplyDeletei think its supposed to be put 2 in front of H if it has an odd subscript, i might be wrong though...
ReplyDeleteHere's a great video on balancing equations. Its a new way that seems pretty helpful.

p.s. nice spelling of tonight
here is a good website on the information what we are supposed to read tonight:

Good site on review stuff, what we're doing now, and a small intro to stoichiometry:

This site has information on the different types of reactions

yeah dont forget that she will randomly assign quizzes so my suggestion is read ahead and make an outline it works very well for the quizzes
ReplyDeletea game to help practice balancing chemical equations
ReplyDeleteA little bit of info to go with tonight's reading.
