Question

1. lets begin to build a model equation for our observations.

the chemical formula of glucose is c₆h₁₂o₆.
select the equation that is described by the claim that plants use matter from the atmosphere to build glucose (and other plant biomass).
c₆h₁₂o₆xrightarrow{light}co₂
c₆h₁₂o₆→co₂ + light
co₂→c₆h₁₂o₆
co₂xrightarrow{light}c₆h₁₂o₆

Explanation:

Plants use carbon dioxide (\(CO_2\)) from the atmosphere. Through the process of photosynthesis (which requires light), they build glucose (\(C_6H_{12}O_6\)). The equation should show \(CO_2\) as a reactant (starting material) and \(C_6H_{12}O_6\) as a product (ending material), with light as a condition for the reaction.

Answer:

\(CO_2\xrightarrow{light}C_6H_{12}O_6\) (the fourth option in the given set of equations).
