Answer:
Oxygen (O2)
Explanation:
This question is describing photosynthesis which uses carbon dioxide and water as reactants in the presence of sunlight to synthesize sugar (glucose) and oxygen. The general equation is as follows:
6CO2 + 6H2O ---> C6H12O6 + 6O2
According to this question, a plant takes in 6CO2 molecules and 6H2O molecules in order to build one C6H12O6 molecule. Using the balanced equation above, the extra element is OXYGEN, which still needs to be released as a gas for the equation to be balanced i.e 6O2 molecules
This is an opinion question, meaning that if you back it up well enough you can't be wrong
Pros to oceans-hydro power
- cleaner (aka better for the environment)
- long term sustainability
- less expensive in the long term
Cons
- initially more expensive
- more hydro turbines are required to offset the energy gained from 1 coal burning plant
- potentially harmful to (a very limited) marine ecosystem
Just pick a side and back it up.
