today in class, we started off with reviewing the hw from last night, which was more element equations (hw can be found on mr. finley's website). we discussed them and helped each other with our tables. after about ten minutes, we picked two problems to review: #s 1 and 8.
1. __2__Na + __2__ H2 O = __2__ Na O H + __1__ H2
8. C7 H16 +__11__ O2 = __7__C O2 + __8__ H2 O
- we also learned that 6 molecules of carbon dioxide is 6 CO2 + 6 water molecules is 6 H2O = C6 H12 O6 + 6 O2, which is the same as sugar.
- SUGAR is used for FOOD
- the "food" is used for growth and for supplements of nutrients for energy to do things
- for example, the mass of a plant is made of water and carbon dioxide becuase the nutreints in it are stored and used for photosynthesis.
- without food, we can die becuase it helps us thrive.

Natalie you made a mistake. Sugar and Carbon dioxide are both used as food. Also, you frogot to include that oxygen is omitted from the plant from photosynthesis. Thanks!

Carbon dioxide isn't used as food. Carbon dioxide is used to make the sugar which is food.
