Answer:
<h2>2.58 mL</h2>
Explanation:
The volume of a substance when given the density and mass can be found by using the formula
From the question we have
mass = 31 g
density = 12 g/mL
We have the final answer as
<h3>2.58 mL</h3>
Hope this helps you
<u>Answer:</u> The moles of carbon dioxide formed in the reaction is 20 moles.
<u>Explanation:</u>
We are given:
Number of moles of butane = 5.0 moles
The chemical reaction for the combustion of butane follows the equation:
As, oxygen is present in excess. So, it is considered as an excess reagent.
Thus, butane is considered as a limiting reagent because it limits the formation of products.
By stoichiometry of the reaction:
2 moles of butane produces 8 moles of carbon dioxide.
So, 5 moles of butane will produce = of carbon dioxide.
Hence, the moles of carbon dioxide formed in the reaction is 20 moles.
Once you add detergent (base) to water (H2O), you are breaking the surface tension.
