<h3>Answer:</h3>

1.9 moles

<h3>Explanation:</h3>

Carbon dioxide (CO₂) is a compound that is made up of carbon and oxygen elements.

It contains 2 moles of oxygen atoms and 1 mole of carbon atoms

Therefore;

We would say, 1 mole of CO₂ → 2 moles of Oxygen atoms + 1 mole of carbon atoms

Thus;

If a sample of CO₂ contains 3.8 moles of oxygen atoms we could use mole ratio to determine the moles of CO₂

Mole ratio of CO₂ to Oxygen is 1 : 2

Therefore;

Moles of CO₂ = 3.8 moles ÷ 2

                      = 1.9 moles

Hence, the moles of CO₂ present in a sample that would produce 3.8 moles of Oxygen atoms is 1.9 moles

What happens to an enzyme if the temperature varies too far from the enzymes optimum temperature?
Licemer1 [7]
The optimal temperature for an enzyme is the one at which the enzyme is the most active and productive.

At temperatures below the optimum temperature, the enzyme still catalyzes the reactions, but with decreased activity.

Even though the temperature increase increases the activity of the enzymes, temperatures that are greater than the optimum cause damage the enzyme strucutre, causing denaturation and loss of function
