Which describes the role of carbon dioxide in photosynthesis?
2 answers:
Answer:
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.

Considering the definition of STP conditions, 3.35 moles of helium are contained within the balloon.
<h3>Definition of STP condition</h3>The STP conditions refer to the standard temperature and pressure. Pressure values at 1 atmosphere and temperature at 0 ° C are used and are reference values for gases. And in these conditions 1 mole of any gas occupies an approximate volume of 22.4 liters.
<h3>Amount of moles of helium within the balloon</h3>In this case, you know that scientist fills a large, tightly sealed balloon with 75,000 mL of helium at STP.
So, you can apply the following rule of three: if by definition of STP conditions 22.4 liters are occupied by 1 mole of helium, 75 L (75 L= 75000 mL, being 1 L= 1000 L) are occupied by how many moles of helium?
<u><em>amount of moles of helium= 3.35 moles</em></u>
Finally, 3.35 moles of helium are contained within the balloon.
