What is the overall reaction for photosynthesis? select one: a. 6 co2 + 12 h2o > c6h12o6 + 6 o2 + 6 h2o b. co2 + c6h12o6 > 6 o2 + 6 h2o c. 6 o2 + 6 h2o > 6 co2 + c6h12o6 d. c6h12o6 + 6 o2 > 6 co2 + 6 h2o?

Plants combine water and Carbon dioxide from the air to make glucose for themselves, and giving off oxygen in the process. So CO2 and H2O would be on ther reactant side (left) with O2 and C6H12O6 being on the product side (right).

Explanation:

The solar system is formed over 4 billion years ago. It is formed from big cloud and gases called nebular.

The nebular collapsed and be one denser. The core of nebular becomes hot and undergo nuclear fusion reaction. nuclear reactions tends to expand it outwards. The gravitational collapse is balanced by the expansion due to fusion energy.

It will then expand and cool to become red giant. It will then shrink and heat up again to become white dwarf. These will slowly cool down for years.
