We talked about our homework wich was review on balancing equations. These are the answers to the homework if you need to correct it:
- 2Na+2H2O -->2NaOH+H2
- Zn+2HCl -->ZnCl2+H2
- 4Fe+3O2 -->2Fe2O3
- 2Al+3FeO -->Al2O3+3Fe
- 2K+Br2 -->2KBr
- C10H16+8Cl2 -->10C+16HCl
- P4+5O2 -->2P2O5
- C7H16+15O2 -->7Co2+8H2O
By now everyone should understand how to do that. If anyone needs help with balancing equations here are somethings you can do:
- Talk to Mr. Finley for extra help during homeroom, studyhall, and before or after school.
- Ask a student that understands how to do it to help you with them in front of Mr. Finley during studyhall or homeroom.
Then we talked about the equation for photosynthesis.
- sunlight+6Co2(carbon dioxide)+6H2O(water) -->C6H12O6 (sugar)+6O2(oxygen)
Then Mr. Finley asked us "What are plants made of?".(According to "You are what you eat".) We replied that ,according to the equation, plants use gases and liquids. Then Mr. Finley went around and handed some students the eleodea we were going to test. He asked if it was solid, they said yes. But how could something that in takes a liquid and gas be solid? The plant takes in carbon dioxide and water, but produces sugar and oxygen. So the sugar helps the plant grow and to be solid. The plant just lets out the oxygen just like humans and animals let out carbon dioxide.
Mr. Finley gaves us a packet for the experiment we are going to do. We answered questions 1-5 on the first page. After we finished and went over the questions, we talked about the experiment we are going to do. Once we finished discussing it the bell rang and we had to go to lunch.

Hey i really still do not get this someone please help!!!!!!!!!!!!!!!!!1
ReplyDeleteThank you for posting this even if its a little late. I wasn't here on friday and this helped me correct my equations. For whoever posted that comment: ^ to balance eqations you have to put either a big number in front of an element (wwhich make the whole thing have that many particles) or a small number after one element (adds just to that letter), until the equations balance. You can not take away though. Hope this helps, if not ask Mr. Finley.
ReplyDeleteNZ :D
also to balance a equation you have to start and end with the same amount. you never start with a little of something and ens up with a lot at the end. so mack shore to not do that
ReplyDeletealso you can make your answer smaller like if you had 4Nat+4H2O~4NaOH+2H2 you can make it 2Hat+2H2O~2NaOH+1H2 like that OK
