Q:

Which of the following equations represents Photosynthesis?

A) 6CO2 + 6H2O -----> C6H12O6 + 6O2	B) C6H12O6 + 6O2 -----> CO2 + 6H2O
C) CO2 + H2O -----> C6H12O6 + 6O2	D) 6O2 + 6H2O -----> C6H12O6 + 6CO2

Answer & Explanation Answer: A) 6CO2 + 6H2O -----> C6H12O6 + 6O2

Explanation:

Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that can later be released to fuel the organisms activities.

Photosynthesis can be represented using a chemical equation.

The overall balanced equation is

$6 {CO}_{2} + 6 H_{2} O \overset{Sunlight}{\to} C_{6} H_{12} O_{6} + 6 O_{2} (S o u r c e o f C a r b o n & O x y g e n) + (S o u r c e o f E l e c t r o n s & H y d r o g e n) + E n e r g y t h a t d r i v e s P h o t o s y n t h e s i s - - - - > S u g a r + G a s p r o d u c e d b y s p l i t t i n g w a t e r .$

Where

CO2 = carbon dioxide

H2O = water

C6H12O6 = glucose

O2 = oxygen.
