Where in an equation for photosynthesis does oxygen belong?
LUCKY_DIMON [66]

Answer:

on the right side, because it is a product

Explanation:

photosynthesis is the chemical reaction with the help of which plants produce chemical energy with the help of light energy.

_______________________________________________

The general standard for writing chemical reaction is that

  • The chemical which are input to the process of chemical reaction are written on left hand side . They are known as reactant.
  • The output of chemical reaction are written on right side. They are termed as product.
  • Transition of reactant to product is shown by arrow.

Chemical reaction for photosynthesis is given by below equation

6CO2 + 12H2O  + light ----------------> C6H12O6 + 6O2 + 6H2O  

We can see that 6 molecules of light combines with 12 molecules of water to give one molecule of glucose and 6 molecules of both water and oxygen.

As, oxygen is the output of photosynthesis process, it is written on the right-hand side of equation and is product of this reaction.

.

Thus, of the options given below for

In an equation for photosynthesis does oxygen belong

on the right side, because it is a product
