Question

Which gas is used in the process of photosynthesis?

Answer 1

Carbon dioxide gas is needed for photosynthesis to occur, and oxygen is a byproduct of photosynthesis.

Explanation:

Carbon dioxide gas is the source of carbon used in photosynthesis to produce hydrocarbons like glucose sugar, fructose sugar, and starches.

In the citric acid cycle, carbon dioxide is broken down, the oxygen is removed, and the carbon is reassembled into a hexagonal structure to form sugar. Sunlight is the original source of the energy needed for these complex chemical reactions. The sunlight is used to produce energy molecules like NAHP, which are used to activate the various steps in the process.

The basic equation for photosynthesis is:

`6CO_2(g) + 6H_2O(l)->C_6H_12O_6 (s)+ 6 O_2(g)`

Answer 2

Carbon dioxide.

Explanation:

The balanced chemical equation for photosynthesis is:

`6CO_2(g)+6H_2O(l)->C_6H_12O_6(aq)+6H_2O(l)`

As you can see here, carbon dioxide gas is used in photosynthesis. When added to water, it also uses light energy in order to convert into glucose. However, sometimes, it can be dangerous to have lots of carbon dioxide in the air.

This is because when carbon dioxide gets dissolved in water to become aqueous, carbonic acid is formed. The equation is:

`CO_2(aq)+H_2O(l)rightleftharpoonsH_2CO_3(aq)`
