Why should the water in the calorimeter be stirred throughout the reaction?
Readme [11.4K]
I think this is done to allow even distribution of temperature in all the regions of the calorimeter. That is to make sure that there are no hot or cold spots and also ensure that the measured temperature is the actual average temperature when the readings are taken by a thermometer.

a sample of carbon dioxide contains 3.8 moles of oxygen atoms, how many moles of carbon dioxide are in the sample?
dedylja [7]
<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
