Question 3 (multiple choice worth 4 points)
(04.02 mc)
what evidence supports a conservation law?
6 co2 – coh1206 +6 02
6 co2 + 6h20 + light – coh1206+6 02
6 h2o + light – coh1206 + 6 02
6 002 – 3 coh1206 +3 02

6 CO2 + 6H20 + light – C6H1206+6 02

Explanation:  

The conservation law states that the number of atoms stay the same before and after a reaction. Consider the following reaction:

6 CO2 + 6H20 + light – C6H1206+6 02

There are 6 atoms of carbon before the reaction, after the reaction also the number of carbon remains 6.

There are 18 atoms of oxygen before the reaction. The number of oxygen remains 18 after the reaction.

There are 12 atoms of hydrogen before the reaction. The number of hydrogen remains 12 after the reaction.

Hence, this reaction is the proper evidence of the conservation law.

c is the correct answer hope this !
