It is a reactant, so it enters the plant.
Explanation:
Hello,
Photosynthesis is the natural process occurring when plants produce sugar and oxygen by using the visible light as the catalyst to undergo the following chemical reaction:
In such a way, it is seen that the carbon dioxide has the role of reactant as it is used by the plant, that is, it enters the plant to allow the photosynthesis to be carried out.
Best regards.

<h3>Further explanation</h3>Given
0.85 moles of Lead(IV) nitrate
Required
grams of Chromium(III) nitrate
Solution
Reaction
Balanced equation :
<em>2Cr₂ + 3Pb(NO₃)₄ ⇒ 4Cr(NO₃)₃ + 3Pb </em>
From the equation, mol ratio of Pb(NO₃)₄ : Cr(NO₃)₃ = 3 : 4, so mol Cr(NO₃)₃
mol Cr(NO₃)₃ =
Mass of Chromium(III) nitrate (MW=238.0108 g/mol) :
mass = mol x MW
mass = 1.13 x 238.0108
mass = 268.95 g
